if i jett my quad and i have an after market air filter will i see a big performance difference? what should i expect? worthi it?

 

I'll let you know after this weekend how mine works out. I'm going from 135 to 142 in the front cylinder and 140 to 145 in the rear on my mains. That's quite a bit of difference in jetting for just a k&n and snorkle/fresh air intake. I originally thought I wouldn't have to rejet and after talking to people they are telling me it leans it out a lot. Looked at my plugs and sure enough they are lean! Getting jets tomorrow and running with raptors and a banshee this weekend. I'll let you know my results. Also I have a vforce with the only mod being the pink epi spring.
