This question goes out to all you phazer II gurus, I am building a extended phazer for my son to ride the Black Hills with. It has a stock motor except a aaen pipe 143.7 is stock jetting, with stock pipe, they recommend a 130-135 main for that altitude in stock form, what do u guys use for mountain riding setups. ??? 
i ran 140's in my aaen piped phazer used between 3-6000 ft. i changed the pilots as well. seems like 100's were better than stock. i had some 110's but never got the chance to test.
