i have an old top tank batavus, with a 50cc engine, and the belt drive on it. might someone know of ways to increase performance? (dont tell me to bore out the cylinder, or shit like that. i have common tools like a dremel, and a decent knowledge of how to do this stuff.)
a new exhaust helped my performance some. I also like those fine wire spark plugs..they're meant for older motorcycle that have magneto coils like mopeds do. They have a smaller electrode and so require less voltage to spark. and they're not too expensive. i havent tried yet, but a larger carburetor is said to increase top end power.
