Default Re: Exaust smoke coming out sprocket cover!!

I know this dude who had a 30 something cc motor and he replaced the pistons, crank and shaft and most components with high strength, light weight alloy steel.. power output boosted to 6kw or 8 hp on the dyno believe it or not.. and this was from a 2 stroke engine that was under 40cc!
