Well I am currently running stock jetting with my K&N drop in and my pure polaris slip on, I am looking to put in 5 or 6 uni vents on my airbox and am wondering wut I should change my jetting to.................I am in winnipeg, Manitoba Canada

 

I don't know canada air but in Illinois I run 170 main and stock pilot run a twin air clamp on just an idea good luck

 

I dont ride enough or have enough time to really test n tune a lot, so I just wanna get my local dealer to change my jetting for me, I'd like to know wut to tell them to put in.

 

If your close to sea level....165MJ with six uni vents

 

Well maybe i'll try a 165

 

Here's another data point...
I was running a K&N drop in with the PP slip on, at sea level, no air box holes. I tried a 160 MJ and it blubbered, so I had to go back down to a 155 main. (150 is stock on mine.)

Another suggestion: If you do not have a CDI, it will make a big difference in performance.
