Atc 250r High Altitude jetting question

[Woodsridder IA]

Hey all, I just moved to Utah from Iowa and I need some help jetting my trike. It is a 1985 250r with V-Force reeds and a FMF Fatty pipe. Stock motor, just resleeved. In Iowa I ran a 142 main and 2nd from the top notch on the needle. I am running a 138 main and dropped to the top notch on the needle. I am lacking bottom end and idling on its own. Any help would be great. Thanks

I had to go with 45 idle (drop) and a 150 main raised it and they idle and run great! I have pipes on both Atc's. I am at 4000 ft above sea level
