Update as of today. Some pics too mr diver.....
Known fact when I bought the bike was the gear change lever didn't return to position, hence a spring is broken. I did ride the bike and had to return the lever with my foot. The engine has to come out to dismantle the external shift mechanism. I've put the engine on it's side ready to use my impact (manual) driver to remove the side casing. (top pic.)
When I removed the alternator the pivot side bolt hole was....... well....missing. A bike club mate over here will weld it back up an drill/tap a new bolt hole. (2nd pic.) That one was a surprise.
Third major intervention is the 'Uni'Trak' linkage the lower arm and dogbones linking the monoshock to the swing arm. (3rd pic.) The lower arm is seized and I need to replace the needle roller bearings and will do the dog bone bearings too. The swing arm bearings were free and greased but I will take a second look there.
On a bright note the rear wheel bearings are fine, brakes have been recently attended to so just a minor service required there as far as I can see. I've a set of standard exhausts to replace the awful bodged pipes and end cans which came with the bike. I might dump the standard (tired) monoshock and put a Hagon unit on in view of the suspension work required.
When I have the rear sorted I'll look at the front wheel, suspension and anti-dive 'thingy' but at the moment I've got enough to think about.
BTW, acetone melts latex gloves.......
