10,000' Ec300

Any suggestions for 9500+ feet, 75 degree average? I have a DDK and CCK for needles. MJ + PJ would be appreciated.

Thats way out of my scope. I'd suggest talking to Les @ LTR if no one else has proven specs. You can also work with the JD jetting spreadsheet, quite a handy tool. I would think that you are going to need needles with a leaner straight diameter than K though. Post your current specs that you are happy with and conditions and I'll try and match something up.

Before I did the RB carb and head mod I ran a 165MJ/38PJ, LTR -0 needle. It worked pretty decent for me. You are going to struggle with finding power at that elevation regardless. My new settings with the RB mods for 8-10,000 are 172MJ/40PJ, CEK needle. The RB mods make a big difference running at high elevation. Everything around here at 10000ft is still under 10 feet of snow!
