I'd pay twice the price to not have to tear into the carb area again. What a PITA! I can't wait for my first valve adjust; just as my bloody knuckles have healed.
JD, you're fantastic! Keep up the good work.

'07 WR on that dyno.
Furthermore, JD offers us tangible, proven results, not some seat of the pants opinion (which, quite frankly is what 97% of the opinions expressed on this forum are). JD offers the jets in the kit that offer the best chance for proper tuning. If you can't get good results with the kit, maybe it's not a jetting issue (AP timing, pilot circuit problems, over oiling air-filters, bad fuel, etc.).

A few of the aspects that go into the WR's JD jet kits are shown below.
Street tire mounted for consistency-
Throttle stop changes-
Throttle marked for tuning each 1/8 throttle range-
Air/Fuel Monitoring for each throttle position over wide rpm ranges-
Gray ignition wire mods-
Steady ¼ ½ ¾ and Full throttle comparisons – Grey Wire vs No Grey Wire
Leak jet and Diaphragm effects-
