Hello folks, here's an update on attempting to adjust the rear tracking. So ok, the left side which I recently worked on is probably easy to adjust, but the right side outer bearing housing, which I think has never been replaced is a different matter. I managed to undo two of the three bolts, but the top forward bolt is very stubborn. It's the one threaded along it's entire length, so I expect it's rusted solid. During this work I disturbed the fuel line which runs along the outer chassis rail, it started dripping, and when I investigated it snapped off, rusted right through where the protective sleeve starts. Misnamed, as this is where water settles, and starts the process.
So I've replaced the fuel pipe, all the flexi hoses, front and back, and of course took the tank out and gave it and the adjacent underbody a coat or two of paint. The brake line which runs alongside the fuel pipe was also looking a bit dodgy, so I replaced that also. I've still not adjusted the rear tracking, but I have a timely warning for you all, check your fuel pipe, as I'm informed by Derek of Renospeed, that this is a common fault, and in different circumstances could end very badly. You have been warned
