I have had success without running for the JD needle. Has anyone tried using different gas? VP makes a fuel with added oxygen called Ultimate 4. Those that have tried it have gotten up to 6% more horsepower. It might be a good solution for the folks in the higher altitudes.
Ride fast-take chances.

1st penny, I bought the JD kit. Before JD stall on throttle snap open at idle and bog a 1/8 - 1/4 throttle. This was a real problem following my son around on his TTR90. When I was behind him and need to lighten the front end I either bogged and slowed down or, worse, bogged and then huge power surge. The power surge usually resulted in a wheely straight at the kid . The JD kit and a little personal advise from JD sloved all of the problems. Also, the bike never started easier. (carb setting is in sig for MI, below 1000 ft.).
2nd cent, I have a spreadsheet that I think I downloaded from thumperfaq.com that does exactly what you guys are asking for. You can use it one of two ways: you can start by putting in the stock MJ, PJ and needle information and the sheet will provide the theretical setting for temp and atitude, or if you have a set-up that works you can fiddle with the "stock" MJ, PJ and needle setting until they match and then you have a slightly better theretical settings. If you can't find the speadsheet I have a copy on my home computer and I can send it to anyone that whats it.

Also, based on my personal experience with JD, that the way to go.
Mparrish, I'm at work now and the spreadsheet in on the home computer so I will send it to you later today or tomorrow. If you don't get something soon send me a reminder.

I ride 6000ft+ everytime I ride and I have a 165 main.
No hesitation, just get up and whoa.
I have the JD Kit and once I set up to JD's instructions it was just a matter of dialing in the fuel screw.

About the leak jet. I feel my jetting is close to perfect but am always looking for better. Have you guys that have changed yours noticed much improvement? And where are you getting them from. Hopefully online because I hate ordering from my dealer.
