mine came with 4 or 5 jets and two needles. The thing that bothers me is the kit was a duplicate of my bikes previous year. No testing, no analysis, nothing went into the changes my bike had being a new year. You simply use one needle and one mainjet and pay $70+ dollars. The man is getting rich and the public is getting ripped off.

If the jetting needs for your new bike was the same as the previous model year, what's the beef? If I was JD, I'd not reinvent the wheel either if last year's kit was spot on for the new model. Did the kit work for your new bike just as good as your old bike? If so, sounds like it was worth it.

With a JD kit, you'e paying for someone else to do the research and testing. I know over the years, I've seen plenty play with jetting, screw it up and wish they'd paid 70 bucks to have avoided the headache. Then again, I know plenty that do their own jetting and it's spot on. The JD kit is not for everyone, but it's definately the way to go for some.

In terms of getting rich, I know when we sell them, sometimes people ask what's in the kit and we tell them to the best of our knowledge. So, I don't see how people are being taken if they don't bother to ask questions they want to know answers for. I've never know JD to hide anything about the kits he makes. You definately can't argue with the success, as there are thousands and thousands of kits in use and the result is consistently good for the number out there.

I used JD for a long time until I bought EFI bikes. Yes it's a little expensive but even if you have any problems he will help you until it is fixed. Now that's money well spent!

I second that. James responds very fast (email or phone) if you need help dialing in the kit. Well worth the $75.

+3 on JD customer service.

Parts in a jet kit vary depending on the bike. What you are paying for is the time James spends testing a kit, and creating the needle. His needles are custom made for each application. Yes, sometimes the same kit is used on different bikes. This is usually because a new model year getting only a change in graphics... well, you get the picture.

If he only sent out on needle and main, what if you lived at a higher or lower elevation? Or a place where the temperatue is drastically different? What if the OEM pilt jet was off? How about needing a different leak jet? Then there are little things he does for specific bikes, like the the DRZ S/SM kits, he includes replacement float bowl bolts to replace the phillips screws.

For those of you who think JD is a rip-off, next time you get a bike, be sure to mention that you think a JD kit is over priced when requesting jetting help . I charge $100/hour plus parts to jet a bike. I take pay pal.

Right, the cost of the kit is primarily to cover the time and work put into testing and creating the custom needles for each application. If he was just throwing in an OEM needle, then yeah, it'd be a ripoff. But he's not. The needles you receive are designed for optimum fuel delivery throughout the RPM range in your specific application. Pretty impressive work, IMO. Price seems more than fair from where I sit.

I have one in my bike. I needed some advice and e-mailed him. I had my reply within a few hours. Perfect advice as well. Worth the money in my opinion.

worked perfectly for my TE450, and i mean perfectly +1 on the JD kit
i've spent hundreds if not near a thousand dollars trying to get FI bikes dialed in, gsxr 1000, z1000, with power commanders... im serious, it takes a pro for that kinda thing

its great to just have the jd kit work for me, simple and good instructions were included
