I was looking on gixxer.com ( i know) and saw the jsd in their store. It claims to increase power in the first four gears and also to get rid of the speed limiter. I have also seen a similar product offered by ivans. Do these work or are they junk. I dont hear much about them and that is surprising. If something was under 50 bucks and it worked i figure somebody would be using them. Opinions
LOOK AT BROCK DAVIDSONS WEBSITE FOR HIS OPINION, THEN MAKE YOUR DECISION.
what is the site address
