[QUOTE="Wilky, post: 919776, member: 56599"] I tried different jetting setting with jets that came with the bike. 30 and 32.5 Pilots 420 and 430 Mains and two different nettles with no real improvement over the stock setup. I heard about the JD kit and gave them a call, explained to them what I was looking for from my CR (more low end) and they said that the kit would solve the issue and if it didn't I could return it for a full refund. I haven’t returned it. So to answer your question....yes and no. I did try some different jet settings but not all available OEM options. I had heard good things about JD and with a money back guarantee I really couldn't lose. The only thing that the kit contains that you cannot get from your dealer is the needles. They are custom made and look a lot different than the stock and in my opinion make all of the difference. When I got the kit at first all I changed was the needle and the low end came alive instantly. The throttle response was much crisper and the low end was noticeably stronger right off idle. I also noticed that the bike was easier to start. I even put the stock needle back in after a couple of weeks just to make sure I wasn't suffering from a new purchase high and sure enough it fell on its face with the stock needle. The JD needle went right back in. I would like to here from someone that has tried both and get their take. Or maybe there is someone in the Phoenix area that has done the carb swap that is willing to do a quick A-B test with me. I hope this helps Scott [/QUOTE]
