Went riding for awhile today. Was running real good. started smelling a strong oil smell halfway through... got almost to my buddies house and started acting boggy. made it to my buddys and shut it off and couldnt get it to start again. pulled plugs and have great spark. But when I pulled plugs the recoil side was slammed shut. Pulled piston to top and it looked fine just a tiny small dimple where it hit. put a new plug in and pulled my A$$ off and never got anything. plugs never got wet or nothing. Havent check compression yet but my buddy held his thumb over all the plug holes and he said I didnt have nothing for compression. Were thinking crank seals? Anyone have any opinions?
