what is the red needle. and is the stock needle jet adjustable? when you say 5th clip do you mean from the bottom or the top. and where can i buy the red needle?

when you buy the JD kit it comes with numerous pilot and mains.. and a blue needle and a red needle. for your elevation and temp you use the red needle. The clip is on the 5th from the top. I think all the jd kits come with it on that position.

The jd kit is definatly worth buying to get the needle and the assortment of jets. This way if you travel somewhere you can easily switch your jets. its well worth the money.

o ya... and while you are working on the carb... you should switch the fuel screw to a CRF only fuel screw...
