I thought I was cool and had the little pod filters replacing the crankcase breather tubes on a 1980 cb750 until oil was leaking out of places where I know had good seals. I applied the concepts in this video and reinstalled the tubes and no more leaks. Thank you.
Thank you so much. Oil was seeping out of the valve cover on my 92 Nighthawk 750 so I changed the gasket but to no avail. Now that I relived the pressure no more leaks.
IT exactly happened to me. put smaller hose into the breather tube ( sporster 1200C ) to take the air and oil out but ended up having oil seeped out of all the gaskets around my cylinder. he is 100% correct.
Good info on crankcase breather! My 1978 750K Honda has a hose plug and recommends draining it periodically, which I do, and discolored yellow fluid drains out! Will now leave it unplugged! may be oil and water, but not sure!,,,,Thanks' for the video!!
I appreciate this video, it definitely helps installing an aftermarket air filter. Because I did not know what to do with the crank case hose. This helps.
I have a vengeance chopper with s&s sidewinder motor and it's pouring oil out of the crank case vent line.Its not overfilled with oil and it's running good
Hey thanks for explaining that very clearly hi Charlotte was some kind of a drain for the battery box actually. Mine had some kind of filter on it it’s a 99 Honda CB 750 but I just clipped that part off and moved it where it can’t be seen so thanks again appreciate it.
Don’t know where Hi Charlotte came from I was trying to explain that I thought that it came from my battery box. So thank you again for explaining that hose for me
Thank YT for recommending this video. I put a mini mushroom filter in the breather hose and drove my motorcycle until I reached 3000km and noticed that the engine oil levels decreased on the sight glass on my crankcase then I proceeded to change my oil. After 600km of riding with the newly changed oil it seems odd that the oil levels decreased again and I noticed that there's an oil leak in my crankcase just below the block. Now this video helped. Thanks.
hi TJ, thank god that i see your video before i make my cb400sf into a street tracker. I wonder if i remove the breather vapor collector attached to carb will make the gas consumption of bike higher?🤔🤔
I have a 2007 VStar 650 Classic puking oil out the output shaft the breather hose is fine bike runs great can I replace the output shaft without removing the motor from the frame????
Thanks for this. Now if you could solve the mystery of the secondary air filter and is it a part of the crankcase breather system I would be happy. I have a vt1100 ace 1998 and although the parts diagrams show it has secondary air filter for the life of me I cannot find it in the location it is supposed to be.
I have a question about the breather air flow on a Twin Cam Harley. Is the air flow from both sides of the breather hole the same or one side seems to be stronger? Great video btw!!
I have a Chinese pocket bike 90cc. The stock air box on the carb has an air line that goes to the crankcase , I want to remove the air box and replace it with a cone filter. Should I leave the air line connected to the crankcase fitting?
So I bought vtx 1300 from a guy and he pulled the ais since he changed the pipes. So as you know it pops after. So the 2 top hose attachment spots like your explaining are plugged both the front and rear ones. As you know 1 sucks in and blows out. My question for you is do I remove the rear one and leave the front sucker plugged?
Thanks very much, you explained it very very easily and practical. Then I asked myself why people still install filters especially in very powerful or old fashioned bikes? By the way, my Honda CB300R's manual shows a pipe which goes down the frame which is closed with a tap and they advise to clean it periodically. Funny thing is since this seems to be a very important task to do frequently on a schedule like cleaning the chain and grease it, check oils levels etc. etc. So has anyone here a similar factory fit and did you take off the tap definitely?
Could crank case possible cause the exhaust header glow red ? You say it could push oil in the the cylinder witch would make it run lean ? Witch could make it run hot possibly?
TJ… Question. Why a hose at all? Like, do you know the design reason why that can’t just be a weep-hole or an open port, and why it instead needs a hose run down to the ground? EDIT: Just watched the second Crank Case Breather video. That breather box doesn’t just output air. It outputs particulates and oil that you don’t want blowing all over your engine and your crotch while you’re riding. That sound right?
@@TJBRUTALCUSTOMS Thanks I got it done. I have a Honda Cb750 1979 . With the heatwave, my engine was hitting over 200f if waiting in traffic. I figured the Crankcase hot fumes going directly into the combustion chamber could only make the engine hotter. Still using the airbox, the crank case input was plugged for now and the hoses went then to a filtered vent - that was smoking a little today. When hearing your logic.

Will this cause oil to become gathered in the exhaust. I have a bike I got from a friend and it smokes and leaking oil on to the ground from the crank case vent hose. Bu it also is getting oil into the exhaust and causes the bike to smike when the pipes get good and hot.
I was paranoid something would crawl up in the hose and plug it so I cut some fine wire mesh (like your velocity stack mesh) and fit it over the end of the hose.
Believe you me nothing on this Earth want to go up that hose. It's oil soaked, smell bad, and once the bike starts it's loud so yeah. In all my years never had anything go up and breather hoses
How much smoke is too much smoke through the breather? I have my vent tube unhooked to keep my air box clean and I’m noticing a bit of oil smoke coming out at stop lights. Is that normal? My bike is burning oil and I think I’ve narrowed it down to valve stem seals. Would that have an effect on the breather?
@@TJBRUTALCUSTOMSI see, Any ideas on what would cause that? For reference its an 81 Honda CB650, it is burning oil and I think I’ve narrowed it down to the valve stem seals. Would fixing that help with the breather or is that another issue?

perhaps a little bit late to the party, but have you found out the cause in the meantime? asking because i think i'm currently having an oil leak from the breather on my suzuki intruder 800
I knew it! I'm stripping down an '03 Shadow Spirit 750 DC and that particular hose is super cracked where it met the back of the air box. GONE!

Although you seem like someone who really knows his sh*t, I can't resist not to put a filter on the crankcase breather. The Idea of having an open tube just seems so counterintuitive. I guess I'll just check it regularly to see if it clogs up. (Thanks for the video)
Why many riders have a plug on the tip of theor breather hose?i saw a video that says you should not plug the hose because it will build so much pressure
I have a 1300 vtx, I put a spike air intake system on it and it came with a small crankcase filter, the problem now is on long rides I'm getting a excessive amount of oil coming from that filter which I know is not normal.

I am now going to bore a hole on the air filter foam because my bike has the intake manifold and the engine breather connected through the stupid stock air box. Because of what you said, I just realized how horrid this stock design is. Thanks! Keep it up.
@@TJBRUTALCUSTOMS that’s what I’m worried about. Shits fucked. I got it pulled, heads, gaskets, cylinders and jackets all look fine. Such a small amount of coolant in the oil you can’t even tell it’s there. Some bullshit.
I am having issues with my 2014 Valkyrie with this vent. There seems to be oil making its way up the tube onto my throttle body and getting into my idle air control sensor. My bike then runs at @ 1200rpm. I have cleaned the vent and I am about to put it back together, but this makes me think that I should reroute the piping to the bottom of the bike. I thought that Honda put it to the airbox for some other reason than to just collect the oil. Thanks for the video.
It's should be in a good running bike such a faint fog of oil that it would just get sucked into the intake air charge and burn off as the bike runs. If this is happening I'd check your oil levels. Oil level can increase crankcase pressure and it will dump excessive oil in to the intake.
Ty in a way that means its actually doing what it supposed to do and releasing pressure? So in a way it works kind of like a pressure realeave valve. Great video thanks again
@@TJBRUTALCUSTOMS ok thanks i was thinking about this and i cut the hose to see if something was in there and there was a little bit sand i dont know if it could suckt it in
A LOT OF PEOPLE. hence why i made this video. people put those crankcase breather filters on and then NEVER wash them. so they become full of oil and moisture essentially plugging the breather. if you want to run a little filter on there, thats cool, but you gotta clean it every few months. wash it with som,e simple green till it doesnt rinse dirty, dry and reinstall.
@@TJBRUTALCUSTOMS So, the EU regulations that vehicles should not be user-maintainable are justified. Legislation should reflect the weakest link in the chain... people, us mortals who know about blow-by/breathers and so forth should NEVER be allowed to even test and re-pump out tyres... in fact, perhaps us "mortals" shouldn't even be allowed to ride our vehicles in case we can't check the oils, coolant and other voodoo elements of vehicular maintenance that the dumb people don't know about.... Only the qualified, licensed, certified, regulated are allowed to even touch vehicles.... that's what it's coming down to.... If you block off blow-by then you need to be neutered - so you cant breed dumbness! PS... what a wonderful rant! 👍
Funny thing, I understand it’s a vent to atmosphere. How come I removed mine and found a sponge and NOTHING but flat bare metal underneath lol I tossed it in trash bin

Only the qualified, licensed, certified, regulated are allowed to even touch vehicles.... that's what it's coming down to....
If you block off blow-by then you need to be neutered - so you cant breed dumbness!
PS... what a wonderful rant!
👍
Funny thing, I understand it’s a vent to atmosphere. How come I removed mine and found a sponge and NOTHING but flat bare metal underneath lol I tossed it in trash bin
James Egnot sponges job is to filter the oil out from being sucked in the air intake
TLDR, dont plug the bitch if you like your motor to not grenade itself.
