Im blowing a decent amount of black mixed with a liiiitle bit of blue tinted smoke when I get on it. When im decelerating I let out a pretty big puff of bluish smoke. I recently over-revved the motor to 9+ rmps but the head has duel springs so does that eliminate valve seals or bent valves? My only guess could be piston rings. How do are piston rings able to take 9krmps without blowin up like these just did? Are forged piston rings alot better?
