ATC200x Carb for XR100--again!

[JeffSutton]

Allright, mates:

I have recently purchased an "alleged" 1983 Honda ATC200x carburetor for an "alleged" 2000XR135 engine--Powroll bored and stroked. (Yeah, I know, I'm going on faith here!) The carb seems very similar in appearance to a stock XR100 carb, just "zoomed in" about 120%! Questions:

1. What is the hot set-up for mounting the ATC200x carb in a most-sano

fashion to an XR100? Details and specifics, please--pretend that I am an

idiot!

2. I plan on running a pod filter--recommendations? (please include links and

or parts numbers)

3. Baseline jetting suggestions--I am essentially at less than 500 feet ASL.

I searched this forum under "ATC200x" and got 50 threads--all good stuff, but not exactly what I needed.

Thanks,

Jeff Sutton

what is in it right now?

For the pod filter go with UNI filters, they are the best.

Also, what pipe? What type of riding? What type of gas?

I am running a 35 pilot and 115 main, ATC200x carb, on my XR120, and I am running a pod filter. Its a little rich for my set up, but you should start around those jets.

Thanks for the help so far--here is some more info:

1. I have yet to run the motor; it came with a stock xr100 carb--main jet size unknown.

2. Pipe is an FMF PowerCore 4, I think--no spark arrestor.

3. It will be used for roadracing and flattrack.

4. Fuel--yet to be determined. Will try 110 and try to go down from there.

Thanks,
