Always an excellent product

Comments On Jun 26, 2015:I bought my wife a CRF150RB. The jetting was way off. I cleaned the carb and installed the JD Kit. After getting it installed and warming up the bike it ran like a champ. Throttle response was smooth and started first kick every time. Takes the guess work out of jetting.

Bike does not miss a beat

Comments On May 29, 2015:I was battling 2 issues (1) bog on hard landings and (b) popping on deceleration. Tried various jetting changes without success. Put in the JD jetting kit and that was the end of the problems.
More power ? Maybe, but the bike already had more power than I could ever fully harness. B Class MX.

Finally set-up the carburation

Comments On Mar 16, 2015:I purchased this kit after 6 years of owning this bike. I bought the bike new and have ridden it less than 75 miles in the entire 6 years I have owned it. I just didn't like it. It wouldn't start easily, it wouldn't idle and banged, popped and farted. I replaced the needle and pilot jet from the kit based on my riding conditions and have been extremely happy with the results.

Didnt work for my KTM here in Ohio

Comments On Jan 12, 2015:Im sorry to say the needles did not work at all for my KTM 300 here in Ohio. Out of this very expensive jet kit the only thing I used was the pilot and one of the main jets. I had to put the stock needle back in. Do your homework and learn about jetting before buying, it will save you a lot of money.

Bought for a trip to Colorado

Comments On Jan 09, 2015:Bought a JD kit for a trip in the high passes of Colorado. I followed the chart explicitly and the set up was perfect, even up to 14,000 feet. Spent 6 days averaging 12,000 feet in elevation and the jetting never hiccupped.
