Default Main Jet Sizes?

Does anyone know what the stock main jets sizes are? Also what are your mains for different stages? Just playing around with the new $500 purchase with 53,000 miles on it. Anyone got any tips on different jet sizes.

Default RE: Main Jet Sizes?

Mine had a D&D slip on, K&N filter, and aFactory Pro jet kit in it when I got it, had 130 mains and the needles on themiddle clip, but it had an aggravating lean/flat spot in the mid range (3000 to 5000) that was driving me nuts. It wasn't all that bad, but I'm **** about driveability. I wound up with 134 mains, and the needles on the middle clip again, along with several adjustments to the pilot screws. I'm VERY pleased with the results, smooth pull all the way from 2000 to past the redline. [8D]
