My RMX250 today all of a sudden start smoking heavy and bogging out at half throttle. The engine has 10hrs since last rebuild and is mixed at 40:1...Do I need to put new gas in? Whats my problem?

Blue smoke, I fouled a plug a month ago so yes its fairly fresh, carb is jetted properly, and I put a new air filter in today...I also just drained all of the gas out of the tank...

Sounds like it's a crank seal.

What would the case be if the smoke was white?

Running too rich, silencer packing oil soaked, pipe has unburnt premix sitting in it, etc.
