hay i am putting a supertrapp complete system and a k&n clamp on and when i went to look at the dyno jet kit it goes from a 126 to a 134. i thought i was going to need to run bigger than that doesnt it have a 134 in it already?

 

i am pretty sure you will need a bigger jet, i am running a 134 in my mojave with the stock air box, if you put on a clamp-on, you will need alot bigger jet to go with the extra air. go to your local store and start buying bigger jets to your plug is the right color.
