JD Jetting guide.

Has anyone here purchased the JD Jeting Guide? If so, what are your thoughs on it, is it worth it?


I love it. It won't tell you how to jet your bike but it sure helps visualize jetting changes.

If you get it, remember that the baseline is some other jetting (I always leave stock for comparison) and it may have weird curves from ideal too.

Good luck,
