This manual will enable even a little old lady who has never owned/worked on a dirt bike to troubleshoot, repair and even rebuild it to make it run like it did when it was brand new. The troubleshooting guide is invaluable. The tool list is very heipful. The easy to follow instructions have pictures and the diagrams show and name every part needed down to the washers. Makes it possible to take it apart and put it back together, and VERY helpful when shopping for parts to know which category to search on websites. When you get it running right, the periodic maintenance guide will help you keep it that way. It contains everything you need to know, even the things you didn't know you needed to know.
