Hey Guys!...ok...so here's a little update.... In addition to caked on sludge and road grime; nice, clean oil is leaking/streaming from where the 'oil feed pipe' connects to the 'cylinder head assembly'...
As for the overheating...IMHO...it's running hotter than it used to run when I first got the bike...of course it could be due to the sludge, road grime, and oil leak...but when i actually ride it, it doesn't seem as hot but as soon as i stop (stop sign or to turn) it starts to smoke and I can feel the heat rising up from the sides... So I'm going to spend some time this weekend trying to correct these problems so I can get back to riding it even if it is just around the neighborhood for now...I'll update y'all a little later on...but for now, any advice or suggestions y'all can offer will of course be greatly appreciated!
