Four main problem areas have been identified and subsequently remedied, which were
- The washer of the oil-pressure switch was a joke,
- the Ignitech produced a slightly unclean signal leading the tach-needle to jump around a little,
- due to the bad weather and riding in the same, the rear brake axle started to feel sticky
- and lastly the bushing for the gear lever was completely worn out, leading the shifter to wobble around in all sorts of directions.
The oil-pressure switch was an easy fix, yet it called for draining the oil.
After some thorough cleaning a bit of flower was sprinkled onto the area and the bike taken out for a spin. If any oil had come out, due to the capillary effect it would have become clearly visible.
Also whilst I was in there a new set of footpeg rubbers were fitted. (The one in the picture is the better of the old ones.)
Next was the Ignitech swap, which unfortunately didn't fully cure the jumpy needle, but it was well worth a try. The blue dot on the plug is to tell them apart.
The last part was to fit a grease nipple to the brake shaft.
Even though I had the shaft out two or three months ago and greased it up nicely with some GOOD saltwater-resistant grease, there's not much greasyness (pun intentional) left in there... Also rather well visible the adjuster is heavily bent from a previous crash and had to be bent back to stock position.
Originally I wanted to do it in the lathe, but with the shape of the backplate it turned out to be impossible to hold in the lathe chuck without making an adapter. So the trusty drillpress had to be employed for the task at hand.
... and the last bit to tackle was to make some proper new bushings for the shift lever. Luckily I had some 24mm stainless steel barstock sitting around that just had to be turned down to 16mm.
And that's the sideplay and the general indifference of the shift lever taken care of.
