I'd move clip to middle put in 300s to start. I'm sea level and think 300 to 320 is where I will be at. I had 310s but went to 300. Ran great but for safety I'm going richer. I've had my bike in woods up to about 1500 ft with 310s at 50 deg and ran good. Just my opinion but I'm no expert. If u can do a plug chop at wot that's the real way.
