    Good morning! I'm a new member to the forum and have used this site quite a bit already to get where I'm at in the build. A little about me: I'm 23 and recently found my dad's 1980 sx650 special sitting around in my uncle's garage. He bought this bike when he was 23 but sold it 6 years later...

    Check New Cam Chain Guide

    I am doing a bit of work on a friends XS sidecar motor during the off season. One thing I do as a matter of course is Heli coil the front cam chain guide bolt holes as I have seen them come loose / break off during a race meeting putting an end to the fun. The guide on this motor is almost new...

I had originally dismissed it as the cause of my problem because it was or seemed to be spot on. I.e pin flush with the end of the bolt and 1-2 mm movement. after looking elsewhere...
