On the suggestion of a co-worker I ordered one of the JD Jet kits . They look to be pretty good but curious if anyone has any review of the company that has used them in the past

In the KTM world, which has horrible jetting from the factory, many swear by them to correct their jetting issues. I did a lot of research, purchased some brass and jetted the bike myself.

Anyone ever use them on the Yamahas?

all your really getting for your money is a needle as the pilots and mains are standard items most of us have already. If you can use the Keihin needle chart it isn't that hard to jet correctly.

X2. A lot of the Gasser jetting kits use a KX issue needle (forget which one) custom made - so no numbers.

I've used and love JD kits. I had one in my YZ 250 and in the 144 project bike last year.
I always start with the JD recommended settings(which is usually real close). My YZ 250 was mostly stock and the JD rec. setting were spot on. The 144 project used the recommended pilot/main/needle, then went 1 clip up on the blue needle and she screamed.

I've been using the JD needles in my KX/KDX hybrid for a little while now. I removed the factory spec needle right away and had been using a needle that is commonly recommended for the KDX engine. I thought I really had things dialed in with that needle. But the JD needle took it to the next level. I wasn't expecting that much of an improvement.

I just wish you could buy the needles only.

JD Jetted KTM 144 here. Love it. Will be purchasing them for the next bike I have to change the jetting on as well as use their website full of jetting information and charts!

Why spend $75 or more on a jet kit when you can do a little research and buy oem jets, needle for about half that? Most bikes come with a manual which will have detailed jet and needle settings info.
components that have no part #s seem to just muddy the waters if you will.
Have bought jd kits before, but realized later that the above advise is a better solution.
my 2 cents.

I've found that some people just don't have a "feel" for an engine and for them jet kits such as JD are a quick and safe way to get them where they want to be.

KTM380's are notoriously hard to jet correctly. JD offers a kit. I bit and put one on my 380SX. Cleaned up only about 15% of the problem. Not a cure but a small step in the right direction. If all their kits behave this way then its not that useful. BUT, the 380 is a particular pain to jet. YMMV

theyre not standard needles... they are custom made triple taper needles which you cant buy elsewhere

In addition, you get a whole set of jets. Meaning if you travel and need to re-jet, you have what you need at your fingertips.
