Hi all,
I noticed the rear of the bike has a rattle so on closer inspection the rear damper rearmost mount (the point where it mounts to the frame), was loose. Clearly its worn over the years, lack of lubrication etc..
So, i removed the rear damper and on inspection was clear it had no oil in it as there was little or no resistance when compressing it. So, i stripped it down and have found it could do with 2 new rubber seals and some fresh oil. Not a problem.
Second issue (and the original one), is the wear in the mounting hole at the pivot point. The aluminium has simply worn through (spoke to Bob at VOC and apparently they were never 'bushed' which came as some surprise to me?), anyway, i can make/get a new pin no problem, but i need to bush the damper. so, 2 questions for the 'learned'.
1. Which type and how much oil goes in the damper? (I have looked in KTB and Paul Richardsons book and cannot see any reference to this?) I know this depends on weight of rider/pillion/luggage/use etc, and have narrowed it down to 3, 5w or 10w fork oil OR brake fluid, any thoughts?
2. I need to 'bush' the damper. The way i view it is the damper is worn, so the worst case scenario is that I replace the damper, but, the damper is perfectly serviceable (new seals and oil given), except for this minor bushing issue. The standard pin/stud (F82/2) is available, so has anyone done this before and what type/size of bush would you recommend?
Many thanks in advance.
Best regards,
Steve.
