Re: How to fit camchain tensioner in the slot?

I always clean up between the cyl fins real good too. a mall file can clean up some of the flashing from casting.

Re: How to fit camchain tensioner in the slot?

Re: Gas tank for 1982 nighthawk?

Very hard to find. One year and only half of the 650's produced. Beware of what you get too. I have bought a couple off ebay "good" and was less than junk.
