Bought this bike from a guy who said it was his practice and hair scrambles bike. I think he said it's had the top end rebuilt, and I know it has at least that I can't remember if he said the whole thing was done. Any way I have this slow-ish leak on what appears to be the right hand side of the motor if you were facing the bars. It seems to be coming from this rubber seal area that I think is the govenor shaft. I have a picture here, it's kind of dark but if you guys can't see anything I'll take a better one tomorrow. Also, there is some gooey black stuff in the silencer area, I know that thing probably needs re-packed, but I was reading that this could be an exhaust issue? The guy I bought it from gave me a pipe spring and o ring kit so maybe that with a repack will help it? I checked the coolant and there was no gunk in it. Talked to a guy when buying my helmet, he said it might just be the seal where the crank case is? Seems like it's coming from where the two engine halfs go together, not top and bottom but side and side, if that makes since. I'm stil a newb to the whole dirtbike engine thing but I have some limited wrenching experience on other things. Any way here's the pic. Thanks for takin a look. I wanna eventually take this thing to the track for my first time when I get all the gear so I wanna make sure it's "race ready" even if I just practice some first.
