i just bought a ct pipe and i cant figure out what jet to use i em going to get a kandn filter soon i want to go riding this weekend but i cant get my jetting right

 

I have an LRD pipe with a K&N filter, and the lid off, and I'm running a #152.5 main jet. I'm also at 4400 ft. above sea level so you will have to richen up being in Oregon. Check your plug after each jetting change to be sure you're not running to lean. Alway's start rich and work your way down. Just thought I would pass on some info to help you out.

 

thanks i wil make sure i keep checking my plug till i get it right

 

I went with a 150 main, needle on the 3rd clip, and the mixture screw 3 1/2 turns out. That is what the Dyno Jet kit suggested. I haven't been able to ride it yet, but at idle and punching it it seems fine, no hesitation and no popping.

 

I 've got the full Yoshi, Pro-Flow with K&N and the air box lid off. I jetted it to Yoshimura's specs on their website. (150 main jets ) I used Dyno Jet's recommendation on the mixture screw (backed out 3.5 turns) and the needle on the 3rd clip. It still starts with just a touch of the start button, it NEVER pops, sputters or any sign of a "flat spot". I'm at about 2500 feet.
