hello every one! i have just brought 2 yamaha yb100's to use as racing bikes (one for my dad and one for me). i have 3 weeks to have them ready. most of the other bikes are suzuki fxr150's (150cc being the biggest 4 stroke aloude and 125cc being the biggest 2 stroke). any how.... can any one give me some advice on setting up the bike, e.g. what fork oil to run, any easy mods to do to the engine and exhaust. the problem i have is its on a budget, allowing $1000.00 to go from scratch to on the track. so far i have spent $180.00 on a r2 racing zip together racing suit, $69.00 on a fox back protector, $375.00 on the bike. not leaving a hell of a lot to spend on mods. i am very capable on doing the stuff my self, i have a full workshop i can access to get stuff done. any help would be great! cheers guys and girls. the main thing is to get out there and have fun, but it is more fun to win races!!!
