Really snappy and has no trouble spinning tires. Wheelies decent. Needs to be geared up though. 11 tooth front is wayyyy too tiny. I think like a 13 or 14 should be good. only goes like 45 or 5 with the gearing it has. If that. Might need a bigger radiator too... Gets pretty hot. I wouldnt trail ride it or any long ride for that matter till it has a bigger radiator. But other then that very fun swap and yeah thats prolly the cleanest that motor has been since the crank was put in... Hahaha but good swap. Very easy. Id recomend it. Would be perfect for a young racer if they are smart enough to run a two stroke right.
