Aye thanks for that, looked them up but can only find the part number for one of the bushes (called a metal slide, number 09&26 on p28). My local Yam dealer said if there's no part code then it's not a serviceable part, but the photo's in P2N's guide and the Haynes manual show two removable bushes...?
I'm more after clarification as to what bits I need to do the full job (seals, oil and bushes).
It's sod's law that if I decide to do just the seals, the bushes will need doing and then I'm stuck without a bike while I find a supplier/they come in stock.
