Need help jetting an 06 EC 250
 

Can you recommend a setup for riding in the Southern California Desert.
2500-4,000 elevation, temp 70-90 degrees, 92 octane pump gas, Amsoil Interceptor 50:1, FMF Turbine Core 2 Spark Arrestor, stock pipe, trail riding only.
Plan to get the LTR Jet Kit
Any help would be appreciated.

Have you search the site yet? There is a jetting post with different settings and recommendations.

Do you know what you are running now? I would start there.

In my 02 running the same altitude you could start with a 175Main and then move to a 172 mostlikely. A 42 pilot and needle at position #2 from top should be about right.

That's what I run on my '05 EC250 here in Phoenix (2000 MSL). It worked well at this weekend's race (3500 MSL).
