How to 1986 Yamaha BW 200 tighten front chain?

Answer 1

Their is no adjustment for the front chain. That's probably why it is so big and not a roller chain. If it is super sloppy and needs to be replaced, a dealer replacement (if available) is probably expensive. Most people just replace them with roller chain (#520?) and compatible sprockets. Check E-Bay. {There is a one time adjustment on the front chain which is the primary chain, the book calls for a O-ring chain. Go to the Yamaha shop and print off the drive chain slack adjustment page and it tells you step by step, you probally don't have the tool so use a punch or make one}
