anyone give me some advice? just picked up a zxr400h1 and when i removed the airbox i saw the 4 airbox to carb rubbers had been ill-fitted onto/into the carbs and were distorted so badly i cant get them circular again, even by warming them up. can i shave the damaged parts off or do i need to get some others? if i need new ones, has anyone got any? i see a few people have fitted race airboxes so someone must have the old rubbers kicking around doing sod all!!!!

also the rear shock is as soft as butter.....whats the dimesions of it: length, top/bottom mounting dimensions? and again, has anyone got one laying around looking lonely...

thanx
