I am wondering if anyone can suggest a good setup for a stock 250XC and TC250 in the woods. Both bikes currently have stock jetting. I live it Texas so I ride anywhere between 400-900 ft elevation and 40-95 degree weather. Running 93 pump with Motorex mixed 60:1. Looking to switch to 98 octane. Any suggestions would be greatly appreciated.

Needle: NECJ
Main Jets: 170, 172 and 175
Piolet Jet: 40, 42 and 45

^^^ I Ran 172 main, NECJ needle 3rd clip I believe, and a 40 pilot in my 14 250SX, Amsoil Dominator 32:1, it ran awesome.
