Since its looks like i need to rejet with these pipes.. What sizes do i need.

Also..is only changing the main jet necessary?? If so, it looks like that can be done on the bike

how tough is doing a total rejet..taking carbs off, etc

Stock main is 132 so one size up would be 134

I have 12,000 miles on my Pipes and have not re-jetted

i talked with my local Kaw dealership and besides the horror of removing the carbs, he questioned whether a re-jet would help performance-wise. He was of the opinion that the needle was the bigger issue and not the jet size. Now that I have cruzers and slightly less performance than stock and I am not going to do a ear shave....I am going to add KN stock replacement filters.. I dont want to go through any extra expense if I dont have to...do I really need to re-jet
