it only smokes if you run way too much oil or you have a twelve bar that is really short and you leave it there for a long time ..i fill mine to just below the top of the sight glass on my 03 636

 

or if your rocking some high rpm whoolies

 

still shouldn't smoke if it's not over full and it has the clean air mod

 

mine will if im running it at high rpm's for a really long distance. im im in the lot its fine

 

fight fight fight

 

my mod works fine, lol

 

+1 if I have a wheelie screamin for an extended period of time, here comes the smoke. As long as the revs are at a reasonable level it has never done it.

 

ok , i never really tach out the bike in a long wheelie so i have never had it smoke like that

 

the only time it really smokes for me is when i'm running behind it like merk stepping but i'm 5'7 with a round bar so its pretty much like a couple inches off the ground so you think i should run less oil?

 

i run mine just barely to the top of the site glass but if yours still smokes from there don't sweat it cause as long as you have the clean air mod it aint hurting any thing and eventually it will find it's own level and stop smoking

 

mine never smokes with the mod......but it makes a funny *** noise after I turn it off

 

i have heard a few people say that but i never heard any ones bike do it ...

the only thing i can think of is maybe the hose some people use is collapsing

 

it sounds like pressure is being released in the oil pan or the belly of the engine....Idk......its purdy kool I geuss....

 

Super vacuum.

 

every single bike I've done a clean air mod too does this

when you shut the bike off, you can hear something releasing pressure about 2-5 seconds later

3 f4i's, and 2 600rr's do this

 

i think it has something to do with the fact that hondas have electronics working the valve and kawis arent. also, those of you who never had smoke comming out of your bike setting it on the bar might be cuz its a honda as well, as theyre breather comes out of the left side where the kawis come out of the back lower of the engine. so hondas normally wont have a problem with hydrolock or oil in the airbox unless its dumped on the left side and the bike doesnt shut off.

 

yes having the vent tube coming out of the side of the valve cover on the f4i is better for bar tricks for sure..

the pair valve should be unplugged when the clean air mod is done so the valve doesn't close that would allow pressure to build in the crankcase

 

i thought it only closed when the bike was off in which case it wouldnt matter cuz theres not pressure being built when its off?

 

im pretty sure it opens and closes under engine breaking ...

or hard acceleration i don't remember which maybe both...lol

 

yeah you need the pair mod bro. oils flowin out the crank case and into the airbox.......
