Mine is a '02 model with just over 5k on the clock, which appears to suffer from loud, clunky gearbox. In particular when engaging first gear, the whole bike jolts as if the clutch was only partly disengaged.
Have bled the clutch, to eliminate air bubbles.
All other gears smoothly smoothly and quietly while on the go, however shifting down is a little slow and requires clutching in and out when stationary.
Any ideas/tips on how to resolve this issue would be greatly appreciated.
