UNI, HMF S/O jetting

[Ukel]

I have a stock 02 400ex with a HMF slip-on and a single stage uni airfilter (if that makes a difference). I bought the pipe from Leesons and they sent a 165 jet with it. I live here in Portland, OR and was wondering what jetting and carb adjustments you would suggest.

well a 165 sounds very high but try emailing HMF to see what they sugjest(sp)

Don't ask HMF they are quiet a conservative bunch. I would start with a 155 and go from there.

I got a 165 or 170 can't remember but that sounds about right but I live in Georgia
