so since i would rather not go pull the carbs off what should a 04 660 have for stock main jets. i am going to pismo on thanksgiving and want to be ready for sealevel and have never played with the main jet just the needle and the clipMaddog56 said:The general rule is to drop one main size every 3k ft above sea level. But often times a jump of 1k-1500 ft will require adjustment of other jets.
Main jets example:
140/145 - sea level
135/140 - 3k ft
130/135 - 6k ft +
cool thanks for the info i should be runing hard for pismo then will just play with the fuel screws and the needleMaddog56 said:Stock 660 has 140 left, 145 right mikuni mains. 22.5 pilots, needles on 3rd (middle) clip. Fuel screws vary.
