Years of experience have taught me that NGK is the best sparkplug you can buy. Not just OK. The best.
Iridium ?
I use a Old rusty Champion Sparkplug for my engine bikes and it works really well
I prefer e3, no sizing and much better
Hey Alex,
That's the g4 cylinder. I have modded mine to work with a gt5 type bottom. The exhaust is timed great and all I did to mildly port it is to remove inside the exhaust port the upper corners wider and taper the port shape into a upside down trapzoid. The cylinder does have sharp burrs inside ports. Remove these and they actually work good.
Literally just bought this kit as my first build. Put it on a Nel Lusso. After assembly I was able to get 39.2 mph on flat ground. I weigh 190 with a 44t. I haven’t even used the high performance carb yet and this thing is a screamer. Definitely needs balancing on the crank though. As well as a 36t sprocket with hub adapter. Next build will be a mountain bike with a stock Zeda 80 and jack shift kit. I ride this thing 40 miles a day to work. Love every second of it. Low to mid power is great but mid to top end this thing comes alive. I actually put the stock pipe on it and got a little better low end tq but lost a little on the top. Swapped for the banana unit. Love this thing though.
nice! max speed?
did you have to use the adapter or will the motor fit directly on the frame? I'm looking at the exact same combo for my first. I wiegh 140 on a good day and live in flat country so I'll use the 36 T. I'm psyched.
@@skipstalforce I weigh 190 and I use the 32 tooth sprocket and it does just fine even on steep hills
I got one of these and i make extreme power once i broke it in but my magneto didnt work the first time and ordered a black one and it works wonderfully
My first MB engine was an older bolt together Z/L rod crank that ran a few thousand miles before it had a air leak. built a AF80 rod high hole engine and that engine makes better power than the Z/L rod engine IMHO Tried at least 4 different jugs on the Z/L rod and none made the power the high hole piston does now. seems like the timing and port locations are better suited for the high hole piston and crank setup. The cylinder shown in the video here is the same cylinder I have but with an iron liner and the transfer ports traditional style not open like the jug in the video. I am impressed with the iron liner over the coated jugs.
if only i had such a motored bike scene in new zealand your vids is as close as i can get to on hand information much respect
Go on eBay you can find them on there....🙂
I have to say, this motor kit FOR ME! IS BEST BIKE KIT IVE LEARNED TO STAY WITH SINCE I STARTED THIS HOBBIE!!!!! very reliable! And long lasting!
You rock Alex!!
Motored life channel is a good resource for all bike problem
I got the same engine for $100 on eBay. After doing some port cleanup mine is great. Best engine you can buy
good as any. same manufactureres... in china... different mfgs making teh same thing. yes port cleanup. oil torque the head bolts to proper torque. oil linkages etc. re torque bolts often as the vibration makes bolts/nuts fall off
building my first motto bike. watching everything Ican
Hit me up if you have any questions along the way!
I actually prefer those 2 bolt chain tensioners as they seem beefier. I just drill out 4 more bolt holes in each corner and they become a 6 bolt super clamp on model. My next experiment will be to wrap the chain stay with i little skate board grip tape. I aslo thought that might work for hub adapter slipage.
Very cool engine. Something I wouldn't expect from bike berry; only because I had order a chain tensioner from them and they left all the hardware out. Then I called them about it and they sent me hardware that was too long.
But hey, their engine kit doesn't look all to bad. Thanks for sharing. Can't wait to see it in action!
Great Mr Alex they disamble of bike berry stafe 4 ,thanks keep sharing more ,& testing.
Hey Dude, You got a true piston port inlet system after run it top off to it near the maximum limit you add some reed valves but do not change the piston porting system here is why you do not. When if these reed valves are large enough, to not limit top end flow rates, they will give you great low-end power too. Effectually widening the power band without detuning the over-all power band. You see at low RPMs the piston port will pray out inlet volume which disrupts the flow through the carburetor this is due to back and forth flow over the jets when high enough causes over-enrichment of inlet charges while also lowering the total volume of the inlet charge. Also, the middle power band gets a boost wich getts better as the rpm gat higher right up to and including. Please test this on a trusted dynameter both before adding and after adding the reed valves. And you will see for your self what I'm talking about I saw on your channel one that would fit the bill it just bolts to inlet port. Mine engine had true piston porting and with a good aftermarket set of Expansion chambers got 87 hp @ 7840 rpm at total 492 cc then I bolted on the reed valves it engine got a full 121 hp crank gear 108 hp at the out shaft of the transmission and 99 hp on the ground bottom of the rear wheel. with the two reed valves set on the bike, I could power up in 5th gear all the way to pegging the 140 mph max speedometer using a total gear ratio 4:1 in 5th gear with no super launch type power at and around 3500 rpm but you feel the power come on there at 3500 rpm. Plus you could near idle rev's less than 1Krpms all day around the park to enjoy the shady trees and cool winds off the San Antonio River, all without overheating and while later win fast start races against nearly full out hop-up rods 1/8 mile, 1/4 mile, 1/2 mile, 1/1 mile, and top end one pint fuel runs mostly 6 miles plus at run out clutch out downshifts down to neutral rolls to stop gasoline high test and winning every time too. I got 154000 miles before the rings got bad never a piston after the final set up was all completed.
The only motorcycles that would beat my 317 lbs empty weight GT 500 @ 492 cc twin were the triples 2cycle two Kawa's ie: the 500cc triple 750cc triple and Suzuki 750 cc triple "water buffaloes" all of these were well tuned. But none ever beat the economy runs if they could beat me on the speed runs. SO! I had the best of both all in one bike without turning a wrench other than normal PM's and always checking for loose fittings, which is something every cyclist rally should do.
This true and factual. All the tuning arts are always beat by low-end torque, which the total product of piston porting with reed valves to properly stop that backwashing at low-revs. THE TRICK IS; getting the reed valves large enough to not limit full flow, yet compacted enough to really limit the backwashing, well at least at a minimum. This system will break sparkplugs insulators due to DETONATION TRICK here is do not cylinder ports up to the magic 180 degrees but to jack-up the whole cylinder barrel to the magic 180 degrees and to keep the lower compression ratio. You do all the right things use real Aviation 200 octane gasoline even advance the spark timing to around 3 degrees to 6 degrees depending on the elevation of the runs use altimeter controlling carburetors you got the winning combination.
Full off crap m8 u dnt even know wat ur on about
I see someone didnt pay attention in school when they tought simple grammar and how to structure a sentence. Or the person is 8 years old.
There's a guy/shop in Montana (I think) that actually cleans up the burrs, machines the rod and case for roller bearings instead of plain bushings, and does a lot more work to them. The engine is called Little Demon or something like that. Cost is like 500 bucks, but you get what you pay for. I almost bought one for my build but wasn't sure about clearance for it on an 07 Iron Horse Maverick 4.0 suspension bike. Instead I mounted a Poulan/Husqvarna 42cc chainsaw engine. I modified the centrifugal clutch to accept 420 chain and tried to use the rear derailleur to have 3 gears. I DO NOT RECOMMEND DOING THIS. The bike would easily go 60+ mph but scary as hell. Especially when the chain bound up and tore the derailleur off. Single speed now 😂.
I just got on waiting for it hopefully its good
No Champion...hands down have the most accurate heat ranges & never foul...speaking from 50 years of experience.Cheers Trev New Zealand 🇳🇿😇home of the world's fastest old Indian 🇳🇿
Excellent video, you know if they ship to Mexico, I would be interested in acquiring one of those engines, either that one or the BT model
Thanks for making the video
You are very welcome!
i drill straight through the chain tensioner and the frame and put a bolt through and make a custom bracket to hold the wheel in one spot AFTER the chain has been stretched and re adjusted 1-2 times depending on how i feel about the chain.
Same here! Half link comes in handy during adjustments. The way I mount the chain tensioner...the tensioner wheel is never slid. It's bottomed out in slot. When chain gets loose enough. I take a link out sometimes a half links required until next adjustment needed. RIGHT AND TIGHT..There is no give when torque is applied to drive tran. Upgrade the wheel on wheel tensioner to a rollerblade wheel grooved out,is my next experiment. These rollers on tensioner with the kit wear out fast!
@@a1driver4hire37 i goto a dirtbike/atv/bike shop and buy wheel tensioners for actual bikes and they last a long time
@@camswee7530 AH HA!! Great idea! I've bought chains at the moto shop...never crossed my mind to check for tensioner wheels! New shopping list!! Thanks! This info can Save me the work of grinding the center of the roller blade wheel out! 👍
@@a1driver4hire37 😄
Looks great. Open transfer ports aren't new, lots of utility engines use them as well as large scale RC engines. They are exactly the same concept but there is less restriction for the fuel/air to come through. That 4 transfer port setup looks like a 5th scale engine inside now, almost exactly. I wouldn't be suprised if thats where they got the idea. Some of those are making 10hp out of 30cc motors with big open transfers and short strokes. I've had one on a Go-ped scooter that was 29cc but would go so hard in the powerband it was hard to control. I feel good about anything that has new design input, that means the whole thing has likley been updated and they're trying to improve the quality of these things. Some of those old designs were just gutless oil pukers, this looks much better.
Thanks for the info!
I bought a cheap motor to start off but it'll be my first time out on one of these 😂 wish me luck out there!
Will it work with a Reed valve?
@@jkoeberlein1 im heard that before. I know what a reed valve is. I grew up under a car. Now a retired mechanical contractor. Tell us about this "reed valve".
Are we talking about intake and exhaust or what?
@@darwanwinkler4125 we use the Reed valve on the intake in conjunction with a exhaust chamber. You have to fiddle with the port timing. I leave this with my nephew, he's the Wizz at this.
@@jkoeberlein1 i see.. thanks that gives me a clue as to what and where its employed. Somehow it aids in larger fuel bites as I dont see how it capable supply .ore air.
@@darwanwinkler4125 the theory as i understand it since there are no valves the as the piston comes up it pushes some of the fuel air mixture back out the intake. The expansion chamber uses the sound impulse from the exhaust and it gets bounced back into the chamber using most of the unburnt fuel. When your port timing is right, the reed valve gives more torque and expansion chamber gives more topend. If you want a better and probably more correct explanation read up on 1970s Yamaha two stroke engines. Personally I believe they are the best two stroke engines ever.
Hey Alex great video for the bbr stage 4 investigation of how it's built seems to be like a very strong built engine minus all the factory defects of the burrs,other than that can't wait for your next video man and that alien Frankenstein we need to see more of that totally have a great one and be safe out there motor life!
Where the he'll do you pour oil into the engine
@@williamlyons5478 into the gas can.
@@williamlyons5478 you don't
built my own high pin piston engine with iron liner non ported jug runs like a dirt bike. stock runtong carb and jet I am at sea level a 7cc fred head MZ pipe no reed runs amazing, great low speed torque, spins a 39 or 36 tooth sprocket wonderfully. cost me like $100 for all the new parts. once engine fires no pedaling needed engine pulls you right along, accelerates like a boss.
Where did you get all the parts
@@killercodplays all over, MZ Miami is local for me Ebay supplies items as well. the secret with these engines is round holes and correct assembly and usage. put 80 miles on mine today. 10/36 gearing is as tall as I want for city use, 10/39 is nice when you have a 30mph head wind 10/36 not so nice..
Is it a motorized bike engine you built or a different one
@@killercodplays bought all seperate parts and assembled it over one weekend.
@@killercodplays The MZ motorized bicycle retailer is 30 miles away from me I buy parts there and from other sources too. just got off my bike now clocked it at 41mph had more but I was happy.
I purchased the same stage 4 about 2 yrs ago my piston is black on top was used to flat land in Florida and didn’t break it in more than 75 miles put 1500 mi atleast I’m replacing my rings and already ordered 5 sets ring better deal and my clutch lever and cable broke just routine maintenance on the several motorized bicycles I have it mounted to a 26 1/2 inch DVR tuning motorized bicycle frame with the gas tank built in it And had to modify the frame mounting a bit new to the bigger size motor studs in the front other than that I love my bike thinking of getting a shift kit put on sure on how to do it with that bike considering it only has one gear on the pedal side
It almost looks like this new 2020 G4 racing engine I got it's just a beast I'm running at 35 mph at only half throttle everywhere
This mortors crazy with the F2 thruster pipe
@Dylan Schmidt 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
Hey dude how did this engine hold up? How is it compared to a stock kit? Thanks. Can’t find any reviews
How fast was your stage 4? The old Angle Fire Engine and the new BBR stage 4 are listed as 2.75+ HP 40mph. This can keep up with a ZEDA80 Triple 40?
THANK YOU FOR SHARING NICE.
These engine kit unboxing videos all look like the warehouse workers play football with the boxes
It's a g 4 cylinder "JL" with open transfer ports and a bridged exhaust. I remove the bridge in the exhaust when porting.
I made the exaust port wider in the insideto port match it. but didnt take out the bridge is that still fine
@@bigdevil1310 of course it's not mandatory to remove the bridge it's just heavily constricted with that bridge. That bridge is totally not necessary.
@@JamesPiccone more porting to do then
@@bigdevil1310 it's not hard you'll feel better when it's done. Just be careful don't take too much off the top of the exhaust or
the bottom of the intake.
@@JamesPiccone how much is to much of the bottom of the intake
Phantom 85 baby sickest Motorized engine out right now
Cool vid!
I enjoyed it
Mine got older tonight and it should be here in 4 days this will be my second motor I had ordered the Dewey from uMoto. And right off the rip it was a disaster I got everything put together it wouldn't start for me about a week and a half to figure out what it was well I guess the factory didn't tighten up the clutch now I got it running finally will three or four days after that it broke down again you got it running for about 3 or 4 days I don't think I even put 200 miles on that bike or that motor and s*** the Piston rings broke. It said broke down 4 days out of the week so I said the hell with it and I'm going to head and ordered me the bbr tuning 80cc
What do you think of the California Motorbike PK 80 kit, and how does it compare to this motor?
Im running same motor not a bbr thou I found the barrel will shed bits of material from small castings in barrel and score it had no marks in piston but a lot in the barrel so you make the call. I did have a lot hp at the bottom.
Patiently waiting for a video of you running this
Just bought a cranny for it
@@MotoredLife does this engine have a balanced crank?
And can I take the cylinder and piston off and fill the case full of oil to lube the main bearings or is that discouraged against
and then drain obviously
Hi bud love your videos one thing I would like to see is a phatmoto bike with a racing engine
That's wat I'm in the process of building hardest problem is keeping the chain away from that big back tire
Throws coil on ground like garbage..
Have you done anything with the bullet train engine yet? I want to buy myself one but iam waiting on you review on it installed on a bike
I'll have it back here soon loaned it out to Steve to make some expansion chambers for them.
What do you do about the casting burrs? Should you file them? Use a file? Do you need to clean with some carb cleaner after or wipe with an oil/gas covered rag? If you could explain or point me to a video where someone does this that would be very helpful!
I ENJOY ALL OF YOUR VIDEO'S I'VE SEEN!! GREAT WORK!
You had the tool in hand measuring the fuel intake! The micrometer tool! Measure the piston/piston chamber!!..wall..etc..PLEASE? I've seen you take these blocks apart so many times..never have I seen you measure the Piston area. I've always wondered those sizes from 48/49/60/66/80...there is no 80cc engine my freinds,that's just a name for marketing? My guess is 48cc 60cc 66cc are the different sizes. KEEP UP THE GREAT VIDEOS!
They only come in 48cc and 66cc. The new bt100 and yd100 are a true 79cc
@@MotoredLife The true cc's is what I always wondered. Thanks for the reply! Also, I watch the video on the 100. COOL VIDEOS!
I use a piece of inner tube between the tank and frame... works awesome
Great idea definitely gonna do that now
Get some 1" or larger shrink tubing and lay it flat to the frame and it will cushion the tank very well and help cut down vibrations to the tank, as well.
Get the larger stud tank too" the regular ones tend to bend /leek from over torqued to keep it from sliding around as well if you don't have a tank frame
Your banana pipe the end where the exhaust exits it's is angled different than the one I received from bbr mine come out straight not to the side and way good video
This motor does look awesome.. but my question is... which motor do you personally recommend for *reliability* I’m into reliability.. and I’m a light guy so it doesn’t take a whole lot to get me moving at high speeds anyways with just a small sprocket upgrade
This motor kit is very reliable !!!!
*And at its heart beats the usual Chinesium peanut butter crank with the potmetal cylinder and cases. Lotsa' luck.*
What exactly does it mean by stage 1, stage 2, 3, 4....what are the differences?
Rear friction. Rear mounted chain driven. Which one would you prefer have you done any videos on them?
I have no experience with chain drive and friction drive has its own advantages but where chain drive wins every time is when the streets are wet. Shuts you down completely other than that wears cheap tires out in a few weeks of riding every day.
Hey Alex I just re posted that video I had to it to screwed it up bikeberry pk80 from three years ago is on there from my huffy 3.0 which was a stage 2 package with race head and chrome valve covers
So is the zeda 80 with its long stroke that you commented on more powerful then the stage 4 80 ?
You should cut one of those high performance CDI‘s and a regular one in half I haven’t seen a video yet it’s like the mystery is it really better check the wire and cut them in half and find out
Ok!
I have 3 of the stage 4's they are okay fir what they are but the added upgrades aren't really worth the price. The g4 cylinders are amazing quick throttle response. The now come with the 4 bolt style chain tensioner but the old dtole pin lock clutch. With some proper port work they can be great engines as long as someone learns the true mix ratio with oil and disregard the bikeberry recommendations for break in. I won't go into detail about the banana pipe nor the hp Dellorto clone that comes with the kit. When dealing with bikeberry if you can get the right person on the phone has the best customer service I've seen yet but you also have to deal with warehouse mistakes the one correction on the video is the bbr tuning engines use a high hole piston not a low hole.the 40mm stroke will beat the piston into the head with a low hole piston. The setups with the g4 cylinder body and zl 40 rod are great engines though.
Can you tell me the proper mixture for a break in?
I prefer a half moon tensioner so it can't fail and jam up the drive wheel.
If you dont have the huge 6 petal reed cylinder, the stock NT carb is the absolute Best unless you have the expertise to convert to a chainsaw style diaphragm carb.
What a bucket of a motor
Hey bud! Got that 5cc head today.
I'm thinking about getting a bike and motor from bike berry but I don't know what engine to get I'm thinking about either the BBR stage 4 or the phantom 85 cc I went speed and don't really care about acceleration
Just one question. Is it a balanced crank? Cheers
I just recently got one of these rods Zmn 80 it's a first time seeing one of these rods on an engine kits the ones I buy off of Amazon I hope it's a good rod please tell me yes or no cuz I can't find much information about this rock loving know you opinion about this rod ? Zmn 80
I have a question I got a stock 4 strock but it vibrates like crazy and is pretty slow how can I fix these issues thanks
What’s the top speed on the stage 4 and what bike would you recommend to put this on?
No clue yet. Im sure not much. And we will see I bought a cranny for it.
I think they should have cleaned up the ports before they sell em especially for the price of a high performance engine do better bbr.
Keep in mind its bikeberry. Theyre hardly able to make a how to video properly let alone build an engine
Bikeberry is a warehouse
@@samhain6953 pretty much yea. Import an engine, change a few bits, add 5hp with stickers and sell it on
True I got one still haven't got it to start I've had it built for 4 months now
Well ML,I did buy the exact same engine. If not for the slot on the exhaust or iui intake (can't remember now) I wouldn't have realized it. I wish you all the luck in the world, sincerely. But as for me,I wouldn't compare myself to you but I do dabble a bit in small engines but could never get that thing started and at the time I wasn't aware of the guarantee so I didn't b ok there and took the loss and kept it for parts. BTW..I already asked you and can't remember what it was about but did you lend your voice to narrate a commercial?
I've been watching videos on motorized bicycles for quite some time ,and I'm not ready to pull the trigger and build my first bike. Your videos are very helpful.
Don't know what motor I'm going to go with right now though .a Taiwan one and just upgrade .or a race one still don't know. . .
Lisa Lee same here.. Im still debating. Please make this guy stop saying ALRIGHT 35000x every video though.
I run the same motor in this video and I beat on it all the time and bone stock have a top speed of 32mph, and I weigh about 270 at the time of writing. I highly suggest
I would really love to see somebody put a turbo kit on one of these bike engine kits
I have one coming
time will tell if it is what it is . port the cyl ports/rough castings as a matter of course?
I had a problem with Bikeberry when I ordered a "SPEED" Carb. They sent me a stock NT carb with a red air filter cover. The "SPEED" carb has a separate fuel valve and uses a banjo fitting.
When confronting them about this, they told me the only difference was jetting. We all know this is incorrect. Throat and slide size is the difference. So you are right, their knowledge depends
on who you talk to. A bit pricey at $24.95 + shipping for a stock NT carb.
Right, Thanks for that info!
Thats prety f-ed up! Sorry that happened to ya bud! Did they ever make it right?
@@ericmcginnis2097 No they claimed they were right. That goes to show the knowledge of a wanta B MBer and a clueless sales person.
Does the stage 4 kit need gaskets and, if so, how many and where?
For a chain tensioner I get a motor mount tensioner for $15 USD on amazon
My petcock fuel valve has started to leak at the connection at the tank. It came apart once and needs replacing. Where can I find one? I checked BBR. They're out. Also, are they mostly universal in size? If so, what's the size? I have a standard tank from a stock nonracing kit. I also have one coming in exactly like the one you have in that kit.
The petcock you can find at just about any automotive store that also deals in lawn care equipment.
@@BeezyKing99 solution found. I ordered a larger 1 gal tank and it came with one.
the best expansion chamber is the one calculated for your engine
Does this muffler still cause the pedals to hit it?
@Motored Life Hey, May You tell me, how is that Engine Holder (You used to review the Engine on), is called,? I'll be Really Grateful 🙏🏻,
Just wanted to find out if a upgraded cdi is most important if I want to get started with a fully stock engine plus would you order these types of engine from online stores like wish ?
Yeah no wish engines lol. And not that ive seen about the cdi. Best single upgrade you can buy is a proper expansion chamber.
@@MotoredLife would you have a preferred supplier of these motors and would they ship to Australia
Those split g4 cylinders are mean once ported
I bought a stage 3 now idk if it's a good idea getting a motor ready frame
How is the motor running im thinking about getting the stage 3
the bbr kit says that the bikes wheels should be 26' is that exact or can it be a larger wheel?
They can be whatever size you want! Just will have to adjust the chain accordingly
Is the clutch any beefier on this engine???
What is the cheapest bike i should but to put a motor on? My bikes frame id to big to mount the motor
I wann see someone put 2 of these engines on a tandem bike ....
This has to happen now
I wanna buy my next kit from this guy..
a homeade tandem bike .useing a jackshaft if necessary...its possible ....
Haven't seen one with two gas motors but I've seen them with two motors and two batteries (electric tandem)
Donate the engines and I'll do it. It would be fun to build.
Is a pull start unit available for the BBR engine?
You're better off to just buy the regular BBR engine and buy the high performance head and the mz65 clone exhaust it's much better than the banana pipe and just use the NT carburetor but jet it accordingly. Or if you want to go all the way then buy a windowed piston and reed valve and a bigger pwk carburetor
I was surprised
hey im having trouble with installing this on my bike, I have a few questions for you. is there somewhere I can contact you at please. Thanks
What kind of trouble?
This engine ran great,but the craftmanship of the engine is poor my bolt holes on the 3rd up grade strip out and were impossible to rethread.,so did two sets of rims from bike berry,and always remeber to locktight your bolts because they come loose. I have bought one engine from the eastcoast and they seemed to be built better from a company called Go MAX TR4o on Bonanza I purchased the PK-80 with the modified piston hole can't wait to see how it rides with my OKO carb...The engine even idles better and smoother'
I just bought a 100cc online for 88total if you want to know we're aske me the one with the red plastic airfilter cover not the black 1
Which motor kit is the best performance racing engine for a bike I want my bike to go fast have some power I just don't know which one to buy I just been searching and looking at every single one I can think of and I just don't know which one should I get and I don't want to spend money on something it's not going to be what I'm looking for.
Wild cat pk80 from California motor bikes as good as it gets for 150 solid engine
That stinger pipe going all the way in is not a restriction. Its a very good way of muffling the sound without affecting the performance. Please dont spread misinformation.
Banana pipes are nowhere near real expansion Chambers and do nothing for these engines so I wouldn't even call that a Stinger at the end! Lol I do really appreciate you watching Blind8686
Motored Life banana pipe IS an expansion chamber, (although not a very good one). That pipe at end (call ot stinger or not) is sticking inside for a very good reason and is not a restriction. If you were to remove the section that sticks inside the chamber, only thing you would gain is noise.
@@blind8686 yep that about sums it up! And you are exactly right the Stinger inner diameter need to be smaller than the header inner diameter to get that back pressure action to push that gas in their back of the engine. This very particular style of expansion chamber from a couple years ago had a pipe at the end that was welded and at the wrong angle and it's literally touching the back of the pipe just caused the outlet hole to only be about the diameter of a pea.

Enjoy your enthusiasm and the unboxing vids are cool because we get to see different products .
Would it be possible to do 1000 / 5000 .? mile checkups to see which products tend to hold together the best ???
Maybe if possible contact some previous clients and get user input from various owners .
I could subscribe to that
Will do!
