i know a kid that put 230 quadsport rear hydrolic brakes on his older styled blaster with not much of any modifaction at all! zilla jugs swap out ,a popular mod is to upgrade your 87 jug with a 88-90 jug for various reasons (intake ,porting,to few head bolts) and the power valves on the 87-up lt250 and lt500 will swap as chris said earlier.though they changed marking on the side of pv adjust cover that used to say 250" on it.swingarms definitly swap up to 1989 on the lts. t bone seat will fit on 85 86 plastic on an lt. thats all i can think of right now anyways. |
