Have nearly finished my kwak400 track bike as my little vfr died last year, was wondering if anyone knows the best place to get carb to airbox seals from, other than a rip off Kawasaki shop?? its an 89 i think, H model??

bumping this as ive since found out...i think that my zxr is a 91 but having trouble sourcing the right rear wheel, its VIN is zx400l-004300 which apparently means its this year, have 3 wheels, 2 that are 1269 and 1 that is a 1251, is there another wheel number im missing???
