questions for those that have installed the Ivans jet kit themselfs

[Rodburner]

says it comes with 4 size main jets why? does this mean you have to keep removing the carbs and trying different jets?

Same question for the needle shims 1/2 step adjustments this seems like a lot of of and off with the carbs. is there any way to see the 

directions before you buy?

To change the main jets you do need to remove the carb set and separate the cabs. To shim the needles you need only to remove the diaphragm and sliders which can be done without removing the carbs.

RR, I believe the 4 carbs have different size main jets....
