Need some advice
Alright, recently I installed a new exhaust/spark plug. I gained a fair bit of speed/power. I generally sit around 60km/h on flat road (I have a speedo). I have a 32 tooth sprocket, do you think maybe I should change back to the 52 tooth sprocket that came with the kit? The only reason being is I'm not sure how high RPM these engien are made to go.
