HMF and K&N Jetting Question

1860 Views 3 Replies 4 Participants Last post by  big4fifty4man
hey guys, I've got a HMF Utility Series and a K&N Filter. I have installed the Jet that came with the HMF kit, but I'm curious if there is anything else that I should change. I've read about needle clips but I'm not sure what they are or if I should change anything. The last thing I wanna do is run my bike too lean.

how is your bike running the way it is now? if your bike is running good then i wouldnt bother with the needle. if it isnt running right then you will have to change some stuff.
If you remove you seat and look at the top of the carb, there is a square cover with 4 screws. Remove them and pull the spring and the slide out. The needle is inside the plastic slide, using a phillip screwdriver make a 1/4 turn to the left on the locking tab inside the slide and it will unlock it and come out. Just be careful not to drop or lose the small spring and washer with the needle. The factory needle has 5 different notches on it for adjustments.

The air/fuel mixture is on bottom of the carb close to the intake. If you do try to adjust it, just remember where you started and only make 1/4 turns or less at a time.

I'm suprised that the direction's that came with the pipe didn't explain the adjustments on the carb for fine tuning.
hey dirty4man have you clipped your carb spring or done the slide modification or anything like that if so what do you do to the slide i know what to do to the spring, i saw it before but cant remember
