Just out of curiosity For those of you who have the JD needles in your bike. Did you jet and tune your bike prior to installing the needle? I was just wondering if it helped the mid range noticably? I have the stock needle now and it runs great but want to know if its worth switching. Im racing it so Im looking for any little extra I can get.

Thanks!!!

The JD needles are great for heavily modifyed air box and high flow pipes. The stock 04 and up needles are plenty good for a slightly modded stock bike. :thumbsup:

If you ask nicely, you might be able to scam someone into selling / giving you the needles. I know I will never use my blue one, no doubt others are in the same situation but closer to you in the states. :thumbsup:

I would try a NCVQ needle before I went to the expense of buying a JD kit. :thumbsup:

I run the blue one here So Cal. It works great. I might try the red once summer gets here.

I just changed to RED needle myself with 168MJ. Blue was fine with the 170MJ for less than 20C/68F. I think you'll find most bikes run a bit RICH with the blue at anything above about 25C/77F at sea level and above, especially if it is humid as well.

BTW: RED clip#5 seems close to BLUE clip#3 - ask JD, they made it and may have exact flow rates??

My .02 worth :thumbsup:
