Are many of you guys using the homemade powernows'on your bikes. I intend to make one soon and will probably just follow the instructions I downloaded from here a few weeks ago. Looks simple enough to me. Has anyone come across any problems or horror stories surrounding this mod? Did you end up having to change your jetting etc? I think this is about the last free mod I have left and would like some feedback from anyone who has been riding with one fitted for a while before I go cutting slots anywhere that they aren't really needed. thanks in advance.
