Surfrjag Posted February 19, 2012 Report Share Posted February 19, 2012 oil seal or oil getting past the keyway maybe Quote Link to comment Share on other sites More sharing options...
Nightmare Posted February 19, 2012 Report Share Posted February 19, 2012 mine was doing the same thing, turned out to be the crank seal Quote Link to comment Share on other sites More sharing options...
dcalsv02 Posted February 20, 2012 Report Share Posted February 20, 2012 definitely sounds like you have a bad crank seal. check your tranny oil level and do a leak down test. Quote Link to comment Share on other sites More sharing options...

Jereme6655 Posted February 20, 2012 Report Share Posted February 20, 2012 i talked to the kid today he wants me to fix it this thing needs so much work theres bolts missing everywhere track headlights are welded onto it theres just so much that was rigged up case is also broke by where the stator cover goes the chain must of broke and hit it That's a normal place to see broken on the cases if the chain brakes. Called chain whack. You have to watch out for air leaks at the crack there. It will show with a leak down test....a lot of people will use JB weld to plug the leak if they are going to be cheap about it Quote Link to comment Share on other sites More sharing options...
UPbansheeRacer Posted February 22, 2012 Author Report Share Posted February 22, 2012 i ran the bike today the oil level was perfectly level where it was suppose to be on the dipstick rode it for 15 20 minutes didnt burn any oil i think its something in the top end seeing as it doesnt burn any tranny oil and i went through the carb twice and tried different carbs im thinking either he put a piston in backwards when he rebuild the cylinder is messed up or its got a stuck ring Quote Link to comment Share on other sites More sharing options...
