Well guys, we installed a hi-lifter ICM, then Ive been working with aaen performance on a new pipe for this machine. We got the second one they made. The problem is that we have a mid and high range lean condition. Being you cant adjust the needle, I am going to need a new needle, or needle jet, or both. Problem is I cant get any tech support on this. I also cant find a good source for keihn info or jetting. The needle in it is a bzl-2.470, the jet is a 3.6#3. The carb is a CVKR-D32. Anybody know who to talk to on this matter, please let me know.

I have a 2004 650 also have the hl module changed airbox intake hose to 2.5 inches & drilled stock muffler. I rejetted mine 142 front 148 rear & put 1 shim under each neddle runs great and plug color is about perfect. Mine was 122 jets stock. hope this gives you a starting point.

 

Thanks for the reply. We have decided to try the shims under the needles. I gave him 130 and 135 mains to try. Maybe im still underjetting the mains. Well see what happens. Good advice, thanks again!

i have 142 & 148 jets and know needle shims also opened intake to 2". got the jets from carb parts warehouse on line. really woke my wheeler up!!!!!!!!!!!!!!!

 

If you are running the stock intake you shoudl be fine with the 130 135 set-up and shimming your needles. There are other carb mods available for better acceleration and perf. as well. Let me know how the pipe works.

 

Ill let you all know how it works when we get er right. With 135's and shimming the needle .035, the customer still thinks it may need more fuel. I had him install a 140 front and a 145 rear main. I havent heard back yet. What else can be done to this for more power as far as fuel/air components?
joe

p.s. he says even though it may still need more fuel, it will kick the pants out of a brute force. he also says that sitting on the tank, on the highway, it will still flip right over in high. Hes quite impressed by the pipe so far. Its the second one out so I havent heard anyone elses opinion yet.

I wouldn't give the credit for the wheelies to the pipe just yet.......the HL electronics takes care of this. But if you're jetting up as much as you are, the pipe is definately adding power.
