You mean the re-bound bushes within the lower forks? Clip-in or bolt in?

Yes and no. Yes you can have them either way round, but there is a correct way round. I don't know what it is; I think the thicker ones go at the bottom but does it matter?

If you want a bit more ground clearance, fit the thinner ones at the bottom. If you're racing, leave them out altogether.

The important thing is to ensure that the forks are level, so the wheel sits upright. Use a home-made shim under one of the bolt-in buffers to straighten the forks out if necessary.

i didnt answer to this........purely cos i was a bit confused ..........by the question................
firstly i assumed that he prob meant the two types of bush above springs/pushrods ................?
in which case generally they are interchangeable...........although in some cases its advantageous to use the washer type/doubled up to give a higher ride height...........
if the question was refering to the upper link buffers,then it is as knowledge advises.......... :D

Simon,

This bush doesn't affect the ride-height, though it can be used to pre-load (compress) the spring. You can fit more than one bush, but don't over-do it, as the spring can become coil-bound.

hi Martin,
yeah i have stand issues. lynx frame.295mm bgm rear shock, mb disc links which i understand have an altered ride height.
the bike leans to one side on the stand with the off side stand rubber around two inches off the ground :shock:
series 3 stand looks straight,measures up the same as two other original italian units.may just weld on extra rod to extend the length.

Hmm. If the forks have been bent backwards, you might have this problem, but I guess you didn't want to hear that, did you?

If it wasn't a Spanish frame, I'd have blamed the stand bracket and the frame cross-member, but them Spaniards make the best Lambretta frames, so that's unlikely to be the cause.

Possibly one of the original 'top hat' type bushes still in one fork leg :?: :?: :?:
