Hey everyone, been reading on the forums for a while and finally joined. I just got an 89 tw 200 and started getting it back on the road. It runs great, has good tires, but I need to change the gearing on it. I live in rural washington, and I need to be able to ride the bike to work (55 mph highways) and go off road a little. Right now it will do 55 at full throttle in top gear with a slight tailwind, and I know that can't be good for the motor. What tooth count sprocket should I use? Ive read on hear that a 14/47 combo might work. I'm running the stock 203/204 Bridgestone street tires. I also need a good place to buy the sprocket and chain.
