Since I have had this Yamaha Timberwolf it has had the problem of blowing oil out the breather, Also if I am running it down a road and look back I can smell oil, So I assume its burning it as well, Plug is a light brown in color. Goes through about a quart in about 7 hours of run time, Some of which ends up in the breather box, How can I remedy this? It has good compression (Rated is 128PSI) 125PSI. And starts without problem with the electric start. I am out of ideas and the cost of oil is killing me. It also has a new problem, It seems to be running wayyy to hot, Its melting the o-rings on the valve covers and starting to melt the plastic on the oil dipstick >_> Its also now burning oil big time when its hot, I am guessing its due to the oil thinning? Or it blew the oilring out from overheating, It makes a cloud of oil smoke at around 5000RPM once hot. I am running out of ideas and do not have a ton of money to throw at it.

 

You are going have to re-ring it. You are building up CC pressure because your rings at toast and that is why you are blowing oil out of the breather.

 

Well, Lots of bad news -_-
