the 86 is a bit faster because it is bassically acr250 top end. plus the 86 has a very thick sleeve, so it does not disipate heat as good but you can bore it over and over again if need be. so far i have never had a problem with mine over heating and it is pretty much stock still. i'v never ridden and 88/89 but my 86 is really good for handleing and jumping. the 86/87 chassis are the same but the motors are a bit different.

The 87 had the long rod engine and as a result is compatable with the 88 and 89 engine kits instead of the 85(atc)-86 kits. The long rod engines tend to make more torque due to a longer duration at TDC and BDC, but the short rod engines rev quicker. 87 was the last year for removable ball joints on the a-arms, but if you're going aftermarket this doesn't matter.
Whatever year you get check the frame carefully for cracks, especially where the subframe meets the rest of the frame.
