my mechanic buddy has a tweaked old dual shock/spring RM 400.. scarey fast.. i could have gotten one of those bikes for free from another friend, but it leaked fuel constantly our of the drain tube for the carb... ran great, but leaked, and i dont know a ton about bikes, so i didnt take it...

alot of people overlook Husky dirt bikes.. stock, they are great, messed with, they are just as fast as any other bike... they know motors...
