1 - Rotary damper on the rear end - Junk it and replace with a real shock first thing - Thye handle pretty well, kind os RC51ish from what i rember, they just didnt have the grunt of the 51's stock-
2 - Ride the wheels off of it ! Good solid motor, makes cool noises when un-corked with a proper set of Yoshimura cans/ full exhaust. Seems brakes were OK, Id spring for S/S lines and some Vesrah pads first thing . Just looks for the normal issue spots, fork seals, oil changes - they arent really expensive to work on ,seems they share some parts with the GSX-R series -
