Went riding today. After doing some hill climbs, started to blow oil smoke out the exhaust near the top. Now I had ridden up this hill 3 or 4 times before this happened. Also the motor started to pop, when this happened. I have 130 miles on it, and only like 1 month left of warranty.

 

Do you have oil in the airbox? Is it overfull? The same thing will happen if you pull wheelies repeatedly as oil travels up the crankcase breather tube and will get sucked into the engine if it doesn't have a chance to drain back to the crankcase. I have read that some guys have installed a catch can on the breather line similar to what the vforces have(not sure).

 

We have seen some cases where the valve seals have popped off of the valve steams.
