i just snorkled my 05 rubicon with 4 1/2 feet of pool hose, but my problem is that at full throtle the misses and sputter. Is this from ot much air or not enough. do you think i need to put a jet kit on it if so what size jet.

I believe you are gettin' too much air. You need to go to a bigger jet. I'm
not sure on what size, but i went 5 sizes larger on mine & it works great.
I wouldn't waste your money on buyin' a aftermarket jet kit. Just get a larger
factory jet.

You can get them from the Honda dealerships or a atv repair shop should
have them.

I would wait until your exhaust is on. That way you only have to rejet once. Not sure
as to what size would be good on the Rubicon. I would asume
that the
stock 170 would be good as most on here who have the Foreman
500's
use the 170. Since the Rubicon is a 500 also, it should be the same i
would think.
I may be wrong though.

on my shoulders.

I'll try to find then jet size, I can't remember it off hand. I think its around 154. The 170 would give you too much fuel, unless you had an excessively large intake snorkel.

no, i don't think is to large, my snorkel is 1 1/2 pool hose and is 4 1/2 feet long. It breathes from under my light pod.

I would start at 160 main (DJ size, not sure what this would be in Keihin), but I would get a jet kit because you can fine tune your needle. You will probably end up with the DJ170 main. Your bike may run just fine with a 160 but at wide open throttle you could be too lean. Do your plug chop. Good luck.
