My son and I have been working on this 1986 Honda ATC 250r project over the last year and it is almost complete. The carb is at Duncan Racing since it was and Honda CR 250 motorcycle carb that was  set up back in the 86 to run on an ATV motor. The motor is from a Honda 1988 TRX250r  which gives it a closer ratio gear box and the longrod motor with a better cylinder. We also installed a TRX 1988 aluminum  swingarm which is -1 shorter than stock. This is the length The Honda ATC Team ran for their motocross  set up.I did not have a Paul Turner or Calfab laying around so we had the mounts built to run the motor and swingarm. It has the HRC short course tank set up but we had to use DC aftermarket shrouds. The pipe is a handmade cone pipe from Kenny Roberts and the silence is a rare Paul Turner made back in the mid 80's. The rear shock was re-valved  and sprung by Race Tech but we are going to have Rob Selvy rebuild an stock shock which performs unbelievable. I also have an Ohlins which we might put back on. The front tire is a Hondaline Racing Pro Comp that is 22x7x10 on a special 10inch rim made for the ATC's. The rear tires are Ohtsu 903 H-Trak's with a 4inch wider Durablue axle. We also used an 1988 CDI box that plugged directly into the 1986 wiring harness to get a better timing curve for the motor. This was not a restoration but a great rider. it should be up and riding next week.

After sitting for a few years I finally got my R together this past winter.  It's not a period correct build but it does have a few rare components from back in the 80s.  I still have a few changes I want to make, e.g., suspension mods, extended axle, but here she is so far.

+2 Westcoast swingarm

Thanks. Not IMS, I fabricated them.

Alot of parts on this ATC are One off parts that I fabricated.

How do you like that carb? What is the jetting on it?

I love the TMX.  I bought another one just recently.  It gives it a very crisp throttle response and just feels good from bottom to top end.  It's a lot narrower than a Keihin, some 76 mm in width, so if you have a small space it fits.  The jets are easy to change.  The float bowl drain plug at the bottom actually holds the bowl in place (plus one little side screw), so you don't have to unscrew 4 phillips like on the Keihin.  It also only has 3 hoses coming off it, unlike the Keihin AS that looks like a bundle of hoses.  Mine came nearly perfectly jetted, although I did drop the pilot from 20 to 17.5.  I kept the main at 370.  For years I stayed away from Mikuni because I heard they were temperamental when it came to jetting, but that's not been my experience.    

I got it from Niche Cycle Supply.  Good prices and fast shipping. http://www.nichecycle.com/ncs/mikuni/carburetors/tm38-27-mikuni-tmx38-flatslide-carburetor-44mm-by-mikuni.html

I don't know if the IMS pegs comment above was directed to me.  Anyway, the 86-87 TRX pegs work with the ATC.

I run the cr tmx.  I haven't tried one of the but is sounds like it is the same. After I put it on and ran it, I sold my Keihins.
