My GS850G ongoing issues and maintenance.

The voltage meter has been waggling around a lot when revs rise over 4k, then settling down. Charging has been unaffected, so I suspected a dirty connection either at the meter feed or even at the reg-rec (SH-775).
Stuck on another reg-rec and the voltage was fine, no waggling.
Put the original SH-775 back on and ditto.
OK, cleaned up the connectors at the 775, put it back together and that's it sorted, seemingly.

Since I'd got it hot, I checked compression figures...
1. 140+
2. 140+
3. 140+
4. 145+
That do for now.

Well, that was an unexpected series of events.
Started off by simply changing the SU needle, then fitting a new-to-me Saddlemen seat. I finished off by checking the cold start and running and set up the idle, etc.
Then I noticed the oil cooler adapter (rather, the o-ring under the OP switch) was leaking a bit. Turns out, some idle sod who'd fitted it hadn't checked the proper fit of the o-ring and it was actually a size too big, so got squeezed out at one end. Stupid git.
That turned out to be an erse of a job, because the clutch cable runs directly across the top of the take-off point for the OP, and I thought I'd take the opportunity to fit a new clutch lever perch from a Dullville.
All together now, and bone dry, but my back is the regulator of how much I can do in awkward positions... flaming sore now.​
