What is the purpose of the Cam Mod? Do you do it with the stock cams? I have a bone stock YFZ that almost dies when I jab the throttle and I have heard that this will fix it. Is this true? I figure that I need to check the vales for the first time it woudl be a good time to do this mod. Do most dealers keep the spacers in stock? Is there anywhere that I can get the manual for free online? Sorry for all of the questions I looked at daddog's site last night and it has a lot of helpful information but obviously I have some additional questions. The video's are great!!! Thanks daddog!!!
