All you need is the owners manual. It tells where every gear and bolt goes to.
Nothing else is needed. I have a ' 98 , it has a flat top piston , is not compatable with ' 97 or '99 cylinders. The bike is slow , but handles like a torquey 125. Suspension was near the top in ' 98 . DO NOT go any leaner than stock , unless you use race gas. Throw away the stock air cleaner element and get a twin air. DO NOT waste your money on a FMF fatty for this bike either, you won't find any extra power that way either.
