Jetting: 2011 250 (38mm carb ASII)

[Jakobi]

Hello everyone.

I'm going to be buttoning up the 250 top end some time soon and as such will want to get a baseline to set the jetting at.

Currently as a 300 I am running 42 N3CJ#2 172 at 300M-1000M 25-35C RH 50-100%. First impressions are to go up a size or two on the pilot and main and 1 clip richer on the needle.

Very interested to know what others are running in their 2011 EC250's and also if anyone has any info re the fuelling requirements between the 250 and 300's that would be great also.
