I have for sale or swap a standard FZR600 Genesis (non-exup) 3HE exhaust silencer. This was fitted to my 1994 3HE but I just used it to get through the MOT when the Scorpion had to come off
£30 posted to UK mainland or i would straight swap for a 3HE rear shock - dont matter if it leaks oil, just as long as the spring is clean.
