well it is cold and hes got a ported motor so even when hes warm he could be around a 330 or 350. My 4 mil with stock carbs was a 370 in the hottest of summer
If you remove the TORS you need to drill and tap the holes on the outsides of the carbs to install the new idle screws since the TORS have the idle adjustment on them originally.

My guess is its lean, if it revs all the way out for 10-15 seconds WOT thats not a rich condition. If I were were me id chop the plug going up the hill WOT for 10 seconds like u say you do and see how it reads. What pilot do you have?
they arent as trendy as they used to be. and if your doing trail and sand pit riding, get some SLP pipes, ive had experience with these pipes and they rock for that application.

yeah just make sure the jetting is good, carbs are sync'd, keep up on cleaning the air filter and uill be good. compression check should let u know where the top end is at as far as life. stock compression is 120 psi
yeah your gunnna be on the leaner side of it since your high alt. u if try and 152 main and it wont rev for crap then uill know lol always better to start rich and work it down
