Hello, Could someone explain how to adjust the cam chain on my xs500b. Is there a link some where? Thanks Jeremy

Assuming your XS500 is the same as my 74 TX500...and that your engine is assembled and timed correctly...and that the TX500 manual on CD I have hasn't left anything out...you set the right cylinder on TDC (ready for power stroke), then loosen the 13mm "acorn nut" that's on the rightside front of the engine, just above the crankcase/cylinder joint. That supposedly allows the spring tensioner to snap "forward" and tension the chain. Next step...tighten the acorn nut back up. Service manuals, both on CD and "real" paper ones, can be forund on eBay.
