You are absolutely right. The bike is used on paved mostly flat ground. Do you have the specifications for the engine sprocket and where can I order it from?
Thanks for the answer. I would like to know your recommendation for what is better and easier changing the front sprocket or the rear one? The rear sprocket is 80 teeth. Are there smaller sprocket that fits? The other question is there a need to change the chain too when changing the front or the rear sprocket? Thanks
Changing the motor sprocket to one that has a double-D bore and bolts right on is the easiest way to go. Changing the wheel sprocket is the second easiest way to go. And drilling and installing a plain bore sprocket onto the motor is the most difficult way to go.
Smaller than original wheel sprockets for freewheels are available on our wheel sprockets for #25 chain page and will fit since they are smaller, however, a shorter length of chain will then be needed since one of the sprockets is smaller. Changing to a smaller wheel sprocket may also affect how the chain tensioner works with the chain as the chain will then be in a slightly different position than it originally was.

I'm would like to have a faster top speed by changing the 11-tooth engine sprocket with a 15 or 16-tooth sprocket. That should speed up the bike about 30% more. Any one has done this?. Please comment.
