Hey, its been a while since I posted anything but I've got a question that I need answered. I knoticed while I was showing off my bike that I've got a small Oil leak at the base of the engine (right below the heads) now after further investigation, (and some professional guidance) I was told that it was probably 90% sure that its the Rocker Box seal. Now... I'm not made of money, however I don't have the ability to drop this engine (nor the space) if it is the rocker box seal... is there any way to get it off without dropping the engine? Please Help!
 
if you have oil UNDER the head, it's a Head gasket. If it's just above the head (right above the exhaust port) it's the rocker box gasket.

I'm doing a top end rebuild on my rear cylinder now, and I had to drop the motor, there's no way to get to the rear head with the motor in place.

Are you leaking from front or rear? (haha, insert dirty jokes here)
 
show us a pic of all of it , and take off your airbox cover & airbox bottom plate , take a look at it and take some pics of it all. it is possible that it maybe just your PCV valves are possibly leaking oil everywhere and dripping down, because of the hose attached to it is very loose, and it's spitting oil all over your rocker box, and down the sides.
when i did my breather reroute i discovered oil all over my rocker box rear cover and down on the sides of it to, had me worried about the same thing,(because i seen the sides first then the top) but it was only the hoses loose on the rear cylinder's PCV valve. but if that is only place with oil on it at the rockerbox seal or head then you got a leaking rockerbox seal or head gasket depending where its at. hope that made sense!
pics of it on this thread about half way downmaybe that might help but post some pics of yours ;

I did a breather Re rout, and I just noticed it, I don't have a catch for my breather just a filter. is that gonna matter? should I put in a catch and clean up and see if that works? I'll post pictures tonight.
 
Well I Changed my Breather Filter, and I'm going to take it to work tomorrow, and for a small ride after cleaning out and spraying it down. I would post pictures but by the time I got out of work today It was already dark and no point really. anyway I'll keep everyone posted.
 
Not the filter. I'm talking about the 2 holes in the bottom of the airbox where the original 3/8 tubing came in.
 
I've got the Airbox Mod on there, so there's no holes in there at all. I re routed the airvents and tried to do it all right, I took the bike out again, and I'm not knoticing any difference right away, but maybe because I'm just used to my bike. I'm going to take it on a decent ride today, and see what I'll find afterwards.. since its nicer outside I'll try and get some pictures in on there.
