1. I just got my son a new YZ85 and after a tank and a half I feel it should be broke-in. I wasn't going to mess with the jetting for awhile but it is spooging terrible. It hasn't fouled a plug yet though.
Any one know how rich the factory settings on this is. My thoughts are to do the same thing I did to my Husky 125 to clean it up, go one size smaller on both jets and drop the needle one position. We are going riding tomorrow and I'm not sure I want to make this many changes at once. What do the power that be think.
#2. Does anyone know if Honda HP2 100% synthetic and Motul 800 100% synthetic are compatible. Like I said we are going riding tomorrow, and both bikes have almost full tanks but I don't have any in my spare cans or any oil left to mix. I want to switch to Motul 800, but I'm not going to dump two full tanks to do it.
