I just got done installing a dyno jet kit on my raptor. I'm running 148/150 mains. 3 turns out on the left carb and 2 turns out on the right carb. Both clips are 4 slots down on the jet needles. Also i have about a 6x3 hole cut into my airbox lid w/ a pro flow k and n filter. It starts bogging down at about 1/2 throttle in 1st and 2nd gear mostly. Any suggestions???

 

i had 148 150, 3 turns out on both, 4thgroove, stock fuel level(sea level) no lid ran well good low and mid. if your higher altitude i think it should be one size lower. thats from one of many set ups in my quest to find the perfect jetting(floatlevels neddle settings air screw mixture settings. LOL ). i dont have a life anymore, i dumpped my gf for my raptor.

 

I think i'm about 900 feet above sea level. Should i try adjusting the floats???

 

i dont know im doing that as i write this too. sixsixt is helping me out he has or had my set up now he has a 686.

 

i would say take off the lid or go back to 146148 22.5 pilots 3turns on both and run it with the lid or take off the lid and run it 148150 22.5pilots 3turns out on both and dont move the fuel level yet. do you have a stock exaust?if not look at the instructions and it says witha stock exaust use 142 and 144 with a modified lid. im reading the sage 2 instructions for under 3000ft. slip on is 144 146 and full xaust is 146 148. you may wanna try those and see how it works

 

Try running it again with the choke on...did this help or worsen the problem?
If it helped you are to lean...my guess
What brand jets do you have? are these Dynojet #'s or mikuni #'s?
The seperation in the a/f screws is generally only about 1/2 turn difference

 

I went to 146/148 jets turned both the screws out 2 and a half turns and moved the clip up to the third notch on the needles and it seems to be running better. Thanks for all the help!!!
