As playades said i would also invest in a good/much better new rear shock - if you can't afford a new and good one - i could offer you to send my original one for the price of the transportcosts from Switzerland-Holland.
It had just 3'000 km's on it's clock - i've unmounted it immediately, when i was getting the machine.

But take the chance to make yourself a christmas-present.....

greets from the south

Andy
