so ive been hearing about these JD jet kits. i have a 05 cr250 and ive been messing around with jetting. supposidly the needles in the kit are supposed to be better than stock. but 75 bucks :whoa: for a few needles and jets? am i really going to see a big jump in jetting crispness?
I'd heard of the jetting nightmares with the 04 cr250 so I bought a JD jet kit and put it in before I fired it up the first time. I started with his suggested settings, played around with the idle air screw and ended up back at his starting point. My bikes been running great ever since. I have over 50 hours on it now and have ridden it in everything from 13 degrees to 95 degrees here in Michigan with no problems. Still have the original plug in it and have never fouled a plug. Can't tell you if that's better than the stock jetting but based on everything I've read it sure sounds like it is!
Wr3cked,
Dude Spend The $$$, It Will Be Well Worth It. Honda's Are Notorious For Screwed Up Jetting Trust Me, You Will Spend At Least That Trying To Figure Out What Jets To Buy. Have You Priced Oem Honda Jets??? Buy The Jd Jet Kit And Be Done With It, You Won't Be Sorry.
James Dean aka JD really does an excellent job on his kits. If you know how to jet you could probably do it without his kit and save a few bucks, but from my experience most people who think they know how to jet are wrong. ;)
I use the jd kit in my 03 cr450 and would recommend it. The circuit transitions are smooth as silk. It also makes it easier to dial in your bike with the two different needles if your climate changes are drastic like here in mizzourah.
I bought one for my 03 cr250 but haven't installed it yet, but my buying decision was based on reading nothing but good things about the kit. My cr's jetting was screwed from the factory so i'm sure i'll love the difference. I'd say buy it if you have jetting problems like me.
oem jets are a rip off but aftermarket jets you can get from WPS or any distributior for $2.50 ... the 05 has cleaned up jetting from the 04 and i have it pretty close now. but i think it can be better. but sounds like this guy has them dialed. and i ride everywhere from sea level to 6,000 feet. ill have to invest in one! thanks for the feedback!
BTW it isnt the jets themselves that are special, it is the needles. The kits come with two needles and a couple of main jets and maybe a pilot jet or two. The needles are where its at.
I wouldn't buy any jets that were not genuine Mikuni or Keihin jets. Yes, no-name aftermarket ones are cheaper. In this case, you definitely get what you pay for.
