I want to renew all the rubber parts in my '73 850's rear iso. There is a vernier adjuster in place by the PO. I don't know whether it's an aftermarket adjuster or one from a MKIII. I have read all the info re doing this without the disassembly covered in the Norton service manual but I have a question. The following is a quote from the method described in an archlived post by Mike Taglieri:
9. The powertrain is now resting on the floor, held up the centerstand,
but it's attached to the rest of the bike only by the front Isolastic.
Now, put more stuff under the rear wheel to raise the frame until the
centerstand almost comes off the floor.
I don't understand the above. If you raise the rear wheel it appears to me that the frame will not move, the engine/swingarm/plates/centerstand will move (upward). If you move this assembly up so that the centerstand almost comes off the floor, what's holding the rest of the bike upright? Maybe I'm just having trouble visualizing it and if I just did it, it would become obvious but it doesn't sound right to me. It seems that SOMETHING has to be holding the bike's frame upright while you jack up the engine/centerstand plates. OTOH, if you removed the shocks wouldn't the bike frame (rear fender) just tend to sit onto the rear tire which would accomplish the same thing (making the iso mount clear the frame tubes) without "lifting" anything?
I apologize if I'm just to obtuse to understand the instructions but Ive read and re-read the article. I then thought maybe if I got looped, that might help (OK, it was actually just an excuse to get looped). But both sober and looped and I still don't "get it."
Any explanation or reference to other material would be greatly appreciated.
