2007 Wolverine 450 Smoking

Hi guys and gals,

I purchased this 2007 450 Wolverine like a month ago.

I changed the engine oil and filter this past weekend. FYI i added 5w-30 synthetic and i added some fuel additive to fuel.

I started it today and once it warmed up i hit the throttle multiple times and this thing is blowing out oil smoke and it never smoked until the oil change.

Any information will be greatly appreciated.

Thank you

check the oil level. make sure you are doing it correctly. i have never had a big bear so i am not positive but every yamaha i have had you check the oil by placing the dip stick on the threads and not threading it in. find the manual for yours and make sure, if it is over full it will smoke. if its not that my guess is your valve seals are weak and the significantly thinner synthetic oil is running past. just another reason i dont run synthetic in a non race motor. it could be rings as well you will either need to tear it down or do a leak down test to figure it out for sure.
