FCR37 High Altitude Jetting Help

I installed an FCR37 mm carb on my 2006 KLX 300 last year. The carb came off of a 2001 YZF 250. I go every year to Colorado riding up to 10,000' alt. I had the bike jetted with 155 main and 40 or 42 pilot. I was a little disapointed, it just didn't have the power that I thought it should have. I just installed a adjustible leak jet a few months ago to hopefully fine tune it. I was wondering if anyone could give me an idea of what they use for jetting (main, pilot, needle clip..etc) their FCR37 equipped KLX in the Mountains.

thanks for you help


I have an FCR37, but it's jetted for 0-1000 ft. That was before the 351 kit, it's too lean now.
