I'm running the Trask check M8 trans cover vented to my external breather system for the heads with a Y and everything goes into a DK Customs catch can. After installing the Trask trans cover basically zero oil comes from either vent and the catch can is always empty; this combination works awesome!
I was wondering if that would work. I have a dk customs external breather with catch can was debating on getting the trans cover from trask. But your comment has me considering doing the same thing.
@@canttalk Did you end up doing this combo? DK customs AC with Trask tranny cover? I am installingmy DK air cleaner and EBS this Friday. Wondering if I should order the Trask part ($350) as well.
Running The Fueling dipstick. Zero issues
Does oil find its way out when you lean into a turn at all ?
I've heard it does.
What's your experience ?
Iv got one on my Low rider and it squirts out oil all over my back tire at highway revs.
Iv been trying to solve this problem for 2 years
@@elusivesambar8657 Run your oil a half quart lower and it'll stop. A1 Mike @ A1 cycles has a video about oil levels with a vented dipstick. I learned the hard way that they're self leveling!!!
With 140 hp & 160 torque you can tell that the motor is running not only smoother but running with ease. Thank you A1 Mike.
Awesome delivery , and well worded !
Thanks for these videos .
As a “ senior citizen “ and having been owning old school Harleys from the 1970’s ( 13 so far ) from a 53 pan head to my now new FXLR 2018 Low Rider , I have been searching for a channel like yours for a long time .
Appreciate you sharing your expertise , sir !
Thank you so much sir! All the best to you!
I have a 19 RGS,installed an S&S 475C cam chest kit with plate and pump.I also installed an A1 ventilator but I put a cheap Amazon check valve in the vent hose to maintain crankcase vacuum.
Hey Kevin, great video, I recently installed (2), yes two catch cans on my 16 Twin Cam Road Glide, one on each cylinder. The bike had 30,000 miles on it when I bought it, and runs well, but I wanted to see if I installed the catch cans, what color or how dirty of blow-by I would find, as we generally are guessing how a motor has been treated by the previous owner when buying a used bike with more than a few miles on it. So far I have found only clean colored condensation from each cylinder, so I think I picked a solid bike for the most part that was well taken care of internally. The reason for my comment today, is not only to endorse your video here, and the reasoning, but also feel the twin catch can system is a great way to monitor the blow by as the bikes mileage and age increases, while not the only indicator of an internal problem that is growing, a very easy way for the DIY guys to monitor the engine internals, and head off a problem timely, before it gets to the “big problem” stage. You do a great job, your a great teacher, and have a well thought out presentation, that keeps your viewers coming back I would bet, I know I do, I only wish I had more time to consume all that your videos offer. Thanks for all you give to the bike community, your channel certainly fills a void, and would be missed if it was not there. Blue Skies!
Great information! Am running the A1 on my 17 Road King with 0 issues. Would be very interesting to know if there is a meaningful amount of cooling associated with not using a check valve.
I can't say either way. To many variables to test really and achieve definitive data.
Thanks for another great video on this topic. It really helps to comprehensively understand the issue.
Glad it was helpful!
Kevin, another great video! Does the vented dipstick allow for a smoother revving
motor? 15:37
I am looking forward to the panhandle!
As always thanks for all the information! Much appreciated
Really helps a great deal Kevin, thanks again! Love your videos from Sturgis!
Thank you for the free education
Hi Kevin I’m Robert love the videos you have helped so many people understand the science with these bikes I have a 2017 ultra limited 107 im running my tran top cover to vacuum ported catch can with baffle straight to intake port on back side of intake manifold with damper and vacuum gauge vacuum is 5 pounds I’m letting breather bolts breath in to catch can and stock oil pump cause with vacuum no aeration in oil and no pressure build up so oil pump will work better .better seal on piston rings and both vacuum/pressure release are serving a purpose in preventing blow by I think a awesome problem solver. Kevin do you think this is a good idea and how much vacuum do you think is best
I have a 2018 CVO with a 117ci…..no sumping issues…..so not doing anything.
Always great information, thanks for sharing your professional opinion, well done! I’m always smarter after viewing your videos!
Hello Kevin and thank you for another excellent video; much appreciated! Can one "over ventilate" a Harley air/oil cooled V-Twin (2021 M8 114 Touring w/Stage-2 in my case; perfectly maintained and no known or observed issues)?
That is, if already running either a Vented Oil Dip (Fueling) Stick or the Transmission Top Cover (Trask), and then add a Filter or Catch Can to the head breather bolts (& air cleaner that does not allow feeding/venting back into the air cleaner/throttle body), would or could this ventilation [by both means] be unnecessary or excessive?
it could be excessive if the venting method adds potential for incoming contaminated air. as with many things, this is a balance. venting the crankcase, then running breather bolts to a catch can wouldnt "over vent". as simple as I can make it....were on different sides of the breather valve....so no issue there.
@@KevinBaxter Thanks Kevin. I'm only utilizing a Transmission Top Cover Plate (with a one-way check valve) for venting the crankcase. No issues on my '21RGS 114, mild Stage-2 configuration (S&S 465 perf. torque cam).
@@tommiller8714 I am also running the transmission cover vent by Trask. How does that 465C cam behave under low load conditions, i.e. going a steady 15mph in 1st gear on a flat road? I have a zippers 468 cam in a m8 107 that runs choppy under that condition. I have a new 114 and want a torque cam that is smooth at the low load conditions but can’t find any reviews that address that.
Enjoyed this informational video. Thanks
I believe I wasted my money on my dipstick vent. After talking too some other V-Twin experienced mechanics, the 103's don't have any oil sumping problems. External breather for heads is all thats needed, unless your running a built high compression motor
Great video Kevin
Interview for Harley owners?
How do you feel after purchasing a HD for $30,000 or more only only to begin noticing it start to use oil and need engine work with as little as 50k (or much less) on the odometer?
Great video. Just a thought, could the trans cover be vented to the throttle body vacuum port with a vacuum valve, post butterfly seeing as the trans cover does not really have any oil mist. My thoughts are keeping more vacuum on the crank case. Am I going down the wrong road with this thought? I am basing this on a standard car PCV system but no oil mist because the trans port is up high. Thanks.
Very good content,nicely done video.👍
I have a new 2022 Triumph Scrambler, 1200XC with an oil leak at the drive sprocket shaft.
I noticed this leak in the showroom before I even bought the bike.
Where are the pressure relief valves on this particular motorcycle?
I’ve noticed oil seeping from the gasket on the bottom cover.
It’s not much but just enough for me to notice a difference in color along the line where the gasket is. That’s excessive pressure because it doesn’t leak at idle. The drive sprocket shaft leaks after each ride, more so if I’ve been in the highway.
The gasket seeping happens after a highway run.
What could possibly be blocked or malfunctioning on a brand new motorcycle that would cause an oil leak because of access crank case pressure ?
Why hasn’t HD introduced a fix for the venting issue so we don’t have to?
Hello Kevin! You mentioned once before that the EVO's had thicker rings then the M,8's. When doing a big bore kit. Do they use thicker rings for M 8's? You also mentioned loosing crank case vacuum by venting breather to atmosphere. Is it possible to use the capped vacuum nipple on top of the EFI back into the crank case to reclaim manifold vacuum?
EVO also had smaller displacement and lower compression ratios....less blow by. Also...they had a mechanical timed breather which was very efficient as well. Too much vac can promote misting and also effect efficiency of the oil pump...i wouldn't do what you mentioned. there is a balance and a case by case.
Hey Kevin,
Doesn't the addition of the oil pumps with the seal virtually eliminate the sumping and the need for added venting?
We can't say that alone eliminates sumping because it can be caused by various things. It has shown to reduce carryover from crankcase to camchest which would overtax the sump side of the pump in the cam chest. There are many, many bikes out there without the seal that have high miles with zero sumping. My opinion is that the seal, in some, is a bit of a bandaid for another issue....but if the bandaid solves or prevents it, all is well. It's kind of like certain sicknesses where the symptoms have to be treated instead of actually curing the sickness. Hope that makes sense.
I'm in Ohio (March). I purchased a M8 114 and have been able to ride it 65 miles. When I pulled the dip stick after a day it was covered in condensation. WHY?!?!?!
I have a 2020 114 Heritage. Got bad sumping after 19k miles, yes even with the improved 2020 pump.. When new I put on the fueling dipstick and DKCustoms head breather both venting with filters. Always got drops of oil coming out of both filters during moderate to hard rides. After the sumping issue I replaced the 2020 pump with An S&S oil pump and cam plate along with a new sump plug. Bike is running fine and no sumping so far however I continue to get the same amount of oil seeping from both filters. Could there still be a problem or is this normal?
I’m curious if these would be advantageous on a stock motor until I get tired of riding around on a “stock” 117?
I chose the feuling dipstick. Stop being so unbiased and tell me mine is best. 😆
So I have done the trask top cover and external intake breather on my 18 RG also have pulled the plug in the bottom of the engine and all I got was a couple drops of oil so I don't believe it's sumping but yet I'm getting not just a oil mist but actually oil from head breathers should do you think I should check the breather valves in the rocker box or you think something else is wrong?
all engines will mist oil...but it sounds like yours is excessive. sounds like you dont have a sumping issue. some will mist more depending on environment, temps, riding conditions, riding style, etc. A leak down and cyl pressure test wouldn't be a bad idea along with evaluating the breather operation. If all is found to be in good order, in your case, venting the head to a catch can would be a viable solution to keep oil carbon from building up on your pistons and rings.
Will it hurt the engine by venting all three location of engine ?
What ever happened to Sealed Power rings?
Welldone. 🙂🤙🤘👍
Could you do a video on venting a twin cam please:) I used a hose and routed my big sucker crank case vent up over and back down behind the rear cylinder
same information applies to all engines really. your fix is good...i have done the same.
@@KevinBaxter could I ask your opinion of putting a one way check valve in line for twincams?
Kevin, correct me if I am wrong. If I do not go beyond Stage 2 I shouldn’t waist my money adding additional crank case ventilation. Not interested in anyone else’s opinion on this issue.
Even in a stock engine with potential elevated crankcase pressure, adding ventilation does not hurt and could potentially avoid issues in the future. If you dont have an issue do you HAVE to do this? no. But...if it becomes an issue, often, other long term damage can occur and you wont know it until its too late for a vent to help you. In other words...it's not a bad idea...even on a stock engine if its in your budget to do so.
What's the promo code for a1?

Hi. Can I ask for your advice on my 2019 road king. I had to upgrade the engine to 117 stage 3 with V&S headers, KW exhaust and Fuel pack tune. The bike has annoying ticking noise (valve noise??) and numbing fine vibration that causes me to loos sensation in my feet. the biggest issue is that with the RPM less than 3 it feels and sounds like I have maxed out on the gear and need to shift ... I basically have to shift quickly to 5th gear and stay below 70 MPH to avoid the vibration and the noise. Would you happen to know what is going wrong here? Is it normal to have these issues with the upgrade? please help I don't and can't enjoy my bike anymore
Attempting to use the discount code you mention in the video. Not having much luck but I'm assuming it's a capitalization issue. Can anyone comment what worked for them?
havent heard that from anyone else....shoot A1 a message. Im sure they will help figure it out. thanks.
I made my own lol
My motorcycle has the best ventilation system already engineered into it on my F117 fighter by combat motors
I would just like to add a note on the vented dip stick vs vented trans top plate on M8 softails. I recently finished installing a 128ci big bore kit bought from you by the way) on my '19 Breakout. I initially added a Feuling vented dip stick but had to remove it because it never would stop discharging liquid out the filter (enough that it was leaving an oil spot and contaminating my rear tire. After removing the Feuling dipstick I installed the Trask top cover and have not had any issues with it at all. I was surprised by this because I've been running a Feuling dipstick on my '19 Road King for some time without any problems. I don't know if the Softails have different configuration on their oil return system or if it was caused by the added displacement, but thought it was something worth mentioning here.
glad you found a solution. routing can have an effect...and the cycle thru the trans could very well have reduced oil coming out as it can condense inside the cavity in the case and separate from the air. thanks.
I had the same problem with A1's vented dipstick... it dumped oil on the road on my 7psi turbo 103 twin cam.. I took it off immediately and went to an oversized external breather at the heads
My 18 Fatboy would spit oil out of Fueling dipstick but on my Lowrider st works great.Both softails
I also had and still have the same issue with the Feuling dip stick.
It vents out oil on my rear tyre and causes a mess but only when I’m at highway speeds. Im disappointed it didn’t work for me as it is quite expensive to buy from Australia. There is still also excessive oil in the throttle body, which i believe causes performance to be inconsistent.
@elusivesambar8657 don't these companies offering these products suggest running a quart less of oil? If so, maybe that is the reason?
Several questions regarding this subject still remain, even after this video, which I appreciate your time and effort in creating. But what I have yet to find, does performing a breather mod, where it is vented either to the atmosphere or to a catch can, hurt engine performance in any way since you a removing a source of vacuum.? I have read articles and watched videos that state that having vacuum in the engine helps pull oil down the cylinder walls to avoid excess blowby. Some say the size of a Harley motor doesn't create enough vacuum to have an effect. But then there are companies like trask and fueling putting in check valves in to let air out but not suck any in, and others like the a1 and dk customs external breather solutions that are wide open
everyone is seeking a definitive solution or specific mod to make. there are varying degrees of severity and several causes of issue. there can't be one singular solution. excessive oil in the tb can create issues. so...if you dont have an oily tb and excessive carbon on pistons, maintain connection to intake. if you do have those issues, vent to a catch can. the long term effects of excessive oil is more harmful than the benefit gained by keeping it in the intake.
@@KevinBaxter Thanks for the great vids - I've enjoyed every one. Re: the question above, he seems to be asking whether vacuum is important to maintain on general principle. And if it is, should a check valve be used to maintain crankcase vacuum? Trask and Fueling use a check valve to maintain vacuum, A1 doesn't. Harley uses valves in their breathers. In your video, you say that they all "do what they say they do," but that doesn't answer the question of whether it's better to have vacuum or not?
Great information as usual, I purchased a Fueling vented dip stick a couple years ago so I am glad it didn’t turn out to be a waste of money.. 😊
Same
I went and got the Feuling vented dipstick and it has reduced how much oil ends up inside the intake by half.
The only real con about the Feuling is the set screw for the cap should have been a standard size Allen screw because the one Feuling used is way smaller than any Allen wrench I have in my collection.
My question is, would it be harmful to my M8 if I added the vented trans cover to work in tandem with the vented dipstick?
Thanks for the videos Kevin. I’m running the A1 dip stick on my 2018 107 with a stage 2 Harley toque cam so far no issues. I did put the catch can under the side cover to protect it from sucking in rain water. I only have about 5000 miles on the dip stick but I think it is helping the oil consumption which Harley says is exceptable.
Gday fellow enthusiasts Have fitted fueling dipstick and Trask top cover on 2020 deluxe Money well spent All good from Australia
2019 Road Glide with state 2. I installed a complete S&S cam chest. I vented the crank with Fueling vented dipstick and vented the primary with Harley’s own primary vent tube. I ran the bike hard from Chicago to Savannah GA and back on vacation. Zero oil sumping Zero oil in my throttle body Zero oil consumption! That’s running high rpm both ways. I’m happy to say I have a tight 107 motor and should probably leave it alone now. So, if your motor is relatively unmodified and still sumps oil or blows excessive into your throttle body you might have issues going on. Make sure your pre 2000 M8 has an updated oil pump and also a place to check is your piston oilers which require removing your cylinders. They could be loose or defective causing excessive oil to dump into your crankcase. Mine were loose from the factory. Yes, I also removed my jugs to check them and also to install better head gaskets with cometic multilayer steel slightly thinner to raise compression. Top everything off with S&S head bolts and rocker shaft studs. Basically replacing most of the weak links that came out of a stock Harley motor.
Will any of this work for an 08 1200 sir?
Kevin do you think even the new 22+ m8s suffer/need the crank case vented? Or even the transmissions? I was told that the 22 fxlrs I have, has a trans vent.
Kevin I loved this Video. I bought a new 21 Tri Glide and added a Catch can and purchased a throttle body vent from DK customs. I know many companies make great aftermarket parts for HD, just wanted to add DK customs to the mix.
All these you mentioned I have purchased from and find all to engineer great products. Thanks for the education on crankcase pressure.
Papa.
True that concerning the water/oil mixture via catch can. Installed DKs set up on both my scooters, one TC one M8, very happy with both, but you must remember to dump them out on occasion. Also installed Love jugs on the TC 110. They make significant difference in engine temp, although they do make rider and pass, right leg HOT… the price we pay for longevity.
Glad to hear the Love Jugs help. Thinking about a set for my 103. Have the catch can and it works. Let's you know when to empty as it starts weeping oil from the can vent.
What about running both dip stick and trans cover 🤔
I have a 2020 Triglide with about 8,000 miles on it. At the suggestion of a well respected builder here in Wi., I plan to leave it bone stock. At least in terms of any engine modifications. I have been giving thought to some sort of vent, mostly to keep oil mist from going into the combustion chamber. I have been checking the air filter for oil contamination and there is virtually none! However if I start to see any I will be looking into a vent that eliminates the breather tubes going into the throttle body. Love your videos!
Hi Kevin, Thanks for all the great videos. I have a 2018 Street Glide with the M8 107. I was hoping to get your opinion. I've been watching a bunch of videos about oil blowby and ways to avoid it. The vented dip sticks, trans covers, and rerouting head breathers to a catch can. I tried the A1 vented dip stick and ended up with oil all over the place. I saw another youtuber ( ua-cam.com/video/bIyaV8KP8HI/v-deo.html ) vent the crankcase through the transmission vent and reroute the breathers to the top of trans cover, letting the blowby oil drain back to crankcase. That sounded good, not having to maintain a catch can, but it still doesn't allow for vacuum in the crankcase, and connecting the crankcase to the transmission did seem like a good idea either.
What do you think about putting two fittings in the transmission cover over the crankcase. Rerouting the head breathers together and tee off to one of the fittings, and put manifold vacuum to the other fitting. Would that provide the vacuum needed for the rings to seal and keep the blowby oil mist out of the combustion chamber?
I appreciate your thoughts and opinions.
Thanks again for your time.
running external hoses to a tee then bottom of frame. no issues
im doing the exact same thing, with no probs at all
Speaking of external breathers, and catch cans: do you think having the breather hose from each cylinder separate to its on catch can would be best or is 2 into 1 ok? I have a 2 in 1 hose set up, and I’m barely seeing any residue in the catch can, and I’m wondering if they are working against each other to prevent the external breather from working as it should.
Great video. I vented my 88TC breather bolts to atmosphere. Not sure what I’ll do with my 23 Street Glide ST. I’ll try to vent that the same way, but I need to look at it when it shows up
Lol back in 1995 build a 131 cubic inch evo lol, way before a lot of people and there a lot of bullshit products out there ,you got a 100 lbs of shit in a 5 lb bag! there not enough crankcase volume to displace the negative pressure. Bottom line & there never will be lol
Late to the game.... but 2024 HDs (117/121)
now have different vent routing from the factory and one off the top of trans/oil cover. Sorry Trask😉🤠✌️
Another great video Kev! I have a 2020 FLHTK and I vented the dipstick, tranny cover and the crankcase. Is it ok to have all 3 vented? I did have blow-by issues but not anymore.
I’m running the Trask top cover. Would there be any advantage to adding either dipstick? If the A1 dipstick could actually lower engine temp I would consider it. My bike runs hot, hotter than I think it should.
I run about a quart and a half of oil in my bike. Never had problems with excess oil coming out.
Would it help a 20l8 H.D Breakout 114ci with less than 10,000 miles ?
Hi Kevin, I have a 2022 Road Glide which comes with a Vented Trans Cover out the factory, does that mean I don't need any of the 4 products you've mentioned in the video? Looking to go as far as just a Stage 2 cam
I’m wondering if there are certain years that this is an issue with? I installed it on my 2017 and it smoothed the motor right out and I picked up 2 mPG. Did HD fix the issue in later models or are they still unvented? Thanks for your time.
Great video and i greatly appreciate your time and expertise. would the feuling dipstick not be rendered ineffective under hard acceleration? With the trans cover that much higher on the cases, would that not be optimal?
Running A1 oil cap. Venting heads to a catch can. $100, cheap insurance.
Did a homemade version of the Trask..... bulkhead fitting, check valve, out to a filter. Checked my throttle body several times and virtually no oil.
Im using moroso catch can
Seems to work great
It catches quite a bit of crap in it! Empty it about every 1500 miles.
What is your opinion about possibly sucking air without a check valve? Is there any possible negative side effects?
Great video man.
I have all my parts together for a SS stage 2 with the 475 cam chest kit. I bought the fueling vented dipstick. I guess if I have a problem with that I'll go with the Trask set up.
With my m8 107 buildup. 129 now. I installed a vented dipstick. I mounted the breather filter on top of the dipstick directly. NOT GOOD!!! Had blowby misting oil getting on the saddle bags. I ran a 3/8 rubber line after the misting on the bike issue to the top of the motor to rest on tip of the intake manifold with the breather filter installed at the end. I have 100 miles on the new performance build. So of course the rings haven't seated yet. Naturally there will be more blow by. Added....I was in 3rd gear at 55mph getting onto the freeway. I pulled 2/3 throttle went up to 65 mph and my rear tire broke loose!!! Scary, but cool!!! Weather was dry, road also. I'm assuming some misted oil got onto the rear tire. I haven't dyno tuned the bike yet. The thundermax is still learning the build up. I created a monster!!!!
Hey Kevin. How does venting the trans, vent the crank case? Are m8's that different?
Thanks Kevin! Zero oil carry over so far at 22k miles on my M8.
AWESOME! You set me straight on the venting from the heads. I WAS gonna get the Trask cover and vent the heads right into that via a Tee fitting, After listening to you, I'll stick with the catch can!! Thanks a bunch!
KEVIN: I've asked this question on a previous video but was never answered so this is a good place to ask again. On that previous video you explained how some crankcase preasure is helpful in keeping the piston rings, particularly the second or middle ring I think, expanded and sealing properly. Would these vents eliminate most or all of that preasure creating another issue?
Thanks
FWS
I would have said some vacuum could be helpful...not pressure. its a balance of pro/con and the actual cause of the crankcase pressure or sumping issue. also....riding style matters, time at high rpms, type of oil, etc. So many variables to this. People are seeking a single cure or single answer...too many variables to arrive at one really. Its a case by case scenario.
Are you in need of a Panhead 65 motor for your show? It would take me a week to get her out of the box and 2 days to build a shipping container. And I will pay for any parts. She's not for sale though. You would have to send her back home. She's in good running condition.
Please email me so we can discuss. Thank you!
I have the Trask Check m8 in my 128 build and seems to be working well. Great video as always Kevin 🙌👏
I have a Stage 4 on my 2018 Street Glide, I installed the Feuling dip stick, it helped a little but at 80mpr I still have oil on my right bag, oil in the breather, my next thought is to do the $12.00 fix and vent it back into the transmission cover in the first port that goes back into the engine, I have the 1 breather can from the vented dip stick and always smell oil, so not happy with that
Check this out .sorry kevin , im trying to put you a picture of my piston top covered in baked on oil.
Long story short
Harley built a pile of shit (again) and it's up to consumers to choose better motorcycles from this century
The information you share with your viewers is mind blowing!!! Thank you for such detail!!!!
Hmmmm, shoulda been done by HD. Now gotta spend extra to get the thing to run right?
Really enjoy your videos, though mates reckon am somewhat geeky as enjoy technical videos. The vast majority of harley owners do not have the technical ability or confidence to vent the head breathers, particularly in the UK though no less in the USA either where ignorance is bliss. Many due to high moisture levels in our cold wet atmosphere have startup issues, cut out issues and high revs coming down gears clutch pulled after a good thrash. Trying to explain that moisture and oil vapour makes a creamy goop that is occassionaly hitting the IAT sensor in the fuel tract and causing the bike to hiccup. That harley will clean all the goop out of the path from head breathers to throttle body and that it will then take a few months to re-create the path to the problem all over again falls on deaf ears. I never had the issue on my first harley but definitely had it on my second, possibly because its less cold and wet well south of Scotland where my second harley came from. Looking to get a 2022 Low Rider S used with as low mileage as possible and vent both the crankcase and head beathers from the get go. Not too later fit the SS cam plate and performance oil pump plus lifters with billet collars. Later fit the Darkhose Crankworks Compensator as a cushed comp definitely seems a better proposition than what harley have been using for decades. I just hope I aint got any swarf left in my crankcase from assembly : O From extensive online reasearch crankcase top vents are far superior to what is effectively a poor catch can on a dipstick, these seem like a very messy option.
Thanks Kevin great info as always. Does the A1 dipstick come with tube and filter or is just vented in the air?
It's a complete kit
Awsome vid nice Procharger box in the back someone is gona get MORE POWER for sure
Probably a foolish question, but having vented the crankcase through the transmission cover (ala Trask M8) is there any need to continue venting through the intake breather bolts? I don't know how to measure the volume of pressure to insure the transmission vent is sufficient and I don't want to blow seals or gaskets. It sure would solve the oil in my air cleaner if I could simply install solid bolts in the breathers.
Why not just cut a notch in the web under the trans cover and vent through the same vent as the transmission?
you then could overpressurize the transmission. its a volume vs pressure thing. you could also pressurize the primary as the primary vents thru the mainshaft of the trans.
Please ,panhead rebuild first see what I have been doing wrong for 45 years
We cant assume anything has been done wrong my friend....45 years of experience speaks volumes! It'll be a little while before I do this as I have to get customer work caught up first.
Always educational! Thanks for the knowledge Kevin.
Too bad the discount code for A1 doesn't work anymore.
Mr Baxter, I have been looking in to the same products that you just did your video on. First some background on me. I'm just a humble Tech that works on Victory, Triumphs and Indian motorcycles. "Polaris" Indian and new Triumphs to be clear. I have done a few Top ends on Indians and have seen the carbon buildup on low mile engines from burning oil. So when I got my new 22 Road Glide I want to prevent what I have seen in a lot of big displacement engines and that is oil in the intake. In the research I have done the breathers that have a one way valve act like a PCV valve on a car. Vents the positive psi but keeps the vacuum in the crank case to help the rings seal and reduce "blow by". That is what I have found.
I have found the same in many engines and engine formats....car and bike, new and old. But not all....based on severity and cause really.
mr perry- with your wealth of working on different bikes which one would you say has the best most efficient engine
Kevin, I talked with another M8 Harley owner who switched his factory air filter with an S&S Stealth air filter kit. I was tired of seeing oil splatter on the front of my left side bag as well as fouling up the cylinders, so I bought one & installed it on my bike. That seemed to have stopped that problem.
Good stuff
Hey, really well delivered lecture on Venting, however I noticed you didnt side on the check valve/vacuum debate, and I suspect the A1 cycle tran plate does not have a reed or a check valve either.. Now my opinion of the Trask..not olny does it (and the Fueling design) vent the crankcase, but are designed to help maintain some level of vacuum that might be present at times. I think its the better unit..except for the under side screws to access the Reeds,.. They can and if they fall out, there can be issues which can cause engine damage.. Trash should have put that access on top of the plate! So I just made my own crankcase vent with check valve system for about $30
From Kevin Hill : I did meet you b.w.w. in Colorado wanting to vent rear cylinder valve cover on hondavtx1300 isn't a bad idea toasting you k.h.
I use the fueling dip stick 114 with a red shift cam this system works great np crap in the catch can making 134 hp and 142 tork great runner
