Can anyone give me the benefit of their experience? I have a 1987 YFM350ER Moto 4, 350cc air cooled. It is spewing oil out of the front left head bolt at the top of the engine, (after it gets hot). It runs great otherwise. Is this a blown head gasket? or something I can safely just use some RTV under the head bolt? Thanks in advance for the help.

 

does anyone know where the fuel air mixture screw is located on a 05 yfz450

 

Where'd that question come from?
