bike barfed oil all over and had to do a tear down from having it at 12 while running....oil in heads, box, everywhere....heard theres a clean air box mod for the 2005/2006 636.....anybody know how its done so i can avoid doing this again?

thanx eric

old man roger

just bypass the air box and disable the air valve on top of your valve cover then block off the two holes left in your air box ..

connect the big hose coming out of your crankcase that goes to the air box with the big hose coming out of your air box that goes to the air valve ..

leave the air valve but disable it so it stays open and acts like a t valve or you can just replace ot with a plastic t valve ..

heres a pic of an 03 that should help you

sweet thanks so much man....now ill be able to keep her at 12 while running and so on without oil barfing all over and going in the box and heads? where does the excess oil go if its connected to the what i think is the smog covers?

old man roger

it will be routed directly to your exhaust ports via one way reed valves that are in the valve cover itself ..

keep your oil level up to the top line no higher and you shouldnt have any more problems , worse case scenario after you do this mod is a bunch of smoke harmlessly pouring out your exhaust if you leave the bike on the bar too long ..

ok sounds great....thank u again....saved me alot of headache....now just to get all the oil out of the heads and change the plugs.....i heard i gotta start it and bubble it out pretty much....thanks again

old man roger

just pull the plugs and crank it over and hope you didnt already do damage

Shouldn't this even eleiminate that?

old man roger

no the bucket in the valve cover that the reed valves sit in are ported to the exhaust so any oil that comes from the crankcase vent will go straight out your exhaust instead of into your air box

hey rodger I havent been riding as much as I used to for the last few years. I bought an 05 to replace my worn 04 did the kleen air mod and now when i'm circling it will smoke or even straight line will do it have double checked everything but its all done right. I never ran the mod on my 04 and never had an issue all I would have to do is empty my pill bottle res. every hour or so in the lot. I know your the 636 guru to ask any ideas on what to check or could my valve just not be fully sealed

old man roger

sounds like you have too much oil in the bike
