Beta manual jetting recommendations have worked out great over 600 miles of 9k-13k ft elevation riding. Runs well at all RPM, good idle. Maybe 1.5 inches of silencer spooge after 60 mile rides. Getting around 40 mpg.

Could you elaborate on what the Beta recommended jetting is? I have to ask, what part of the world are you in that you have been able to ride 600 miles at 9k to 13k elevation?

Thanks, I could never get the N2ZX to run clean off the bottom but I was afraid to go below 165mj at sea level.

Mileage even better this year, never less than 45 mpg, usually 46-48mpg. Even less spooge .Nice not to have to buy a larger tank.

Ditto for 2023, consistent 48 mpg. One correction to earlier post, I've been using a 155 main, not a 158.

Yeah, sipping fuel at those elevations. Probably feels like a 200. Ever thought about a S3 high elevation head?
I’m PNW at sea level to 4000’.
Amsoil interceptor at 50:1. Factory Fatty pipe, 65degF is 38 pilot, air screw at 1.25 open, NECH at clip 3, 170 main…no spooge. I probably need to go with a 40 pilot
