I fitted a jd kit to my 2001. Just followed the instructions that came with the kit, dropped the main jet down one size and the needle down one notch and what a difference. My riding buddies say my 2001 is the best performing of a mix of later model Honda and KTM's.

Go for the jd kit, it works just fine.

Go through your carb real well, maybe dip it overnight and use compressed air to make sure its real clean on the inside. Is the PV good and clean? The 01 was supposed to be the last really good CR motor of the Honda smokers.

i had a 01 cr250 an had both carbs and wound up liking the tmx more. The tmx need the float lower a good bit then try a 410 main stock needle clip#2 slot and i can't remember on the pilot it was a 32 or 35 with the air screw about 1 1/2 to 2 1/2. it work very well.

Well I did order a jd jet kit but I also did a couple things last night. I dropped the clip to #2 slot and went to 32 pilot and went up to 430 main which is confusing to me because stock is 420 so why add gas unless it has to do with changing the clip. I did warm her up and she def runs alot cleaner down low and went good up and down the road but Until I ride it good and put her under load I will not know for sure.

I went with the jet kit because he said if I was not happy i could return it for full price and use the money for his kehin and jd kit already installed.

You are very close to what i had so try and go down on the main to 410, unless you are going to be running wide open like riding on the road the 410 should get you a good clean jetted carb with the plug looking lite to dark brown. You float level maybe ok but i had to drop mine some.

I have the same bike and live in MI. I went with the JD kit, it has real good down low grunt and wicks right up, nice and crisp throttle to. Been running that set up for three seasons now. Also remember the kits jets are going to flow better then oem, no issues for me...

Search this forum for the S-9 to S-8 nozzle swap for the Mikuni TMX. Might save you some $ and time. If if works fine...don't fix it and go riding!

Jets r us has them for $20. Seems like a cheap try before you sink $220 into your bike.

definitely sounds lean numbers wise, but the bike runs great and the plug looks awesome. no pinging/detonation.

just pulled the head off last night as well to do some inspections. everything looks great.
