Hey all I'm new to the forum! About 10+ years ago my uncle gave me a 1985 trx250 that he had bought in 1990. I have used it plenty throughout the time I've had it but the past couple of years it hasn't been running. I just ordered a key switch, ignition coil, voltage regulator, and stator for it and I'm pretty sure that the main problem is the stator. After I get the bike running I would like to rebuild the top end. Is there a high compression piston available? I would also like to add a bigger cam. I've heard that a Big Red cam has more lift and that an 88 300 cam is larger, can anyone confirm this?
