Hey people, looking for some help, 2000 yamaha grizzly, starts and runs for about 5 or 6 minutes then seems to load up somewhat then quits, on restart blows oil smoke and some raw oil out the tail pipe, runs for another few then quits again. The exhaust was broken at the muffler but that has been sense repaired and now wondering where to turn next. Thanks in advance for any help[. Phil The Fireman

 

Make sure its not a vapor gas lock. If it runs fine with the gas cap off its a gas tank venting problem.

 

ill try that, thanks
