4mm stroker jetting question

Heres a quick question for ya guys, before we meddle around with someone bike, he has stocker carbs w/ k&N

 

plugs look perfect

top, mid, and bottom end are great

BUT

it has a slight hesitation when you first peg the gas

 

would this be needle position?

what way should he move the clip?

would this have anything to do with the pilots?

you can also try the air mixture screws....screw them in will cause a richer condition..if it is solved great or better then pilots are too small. effective range i believe is half turn out to two and one half turns out...good luck..D ;)

Ray, I have had that problem too. It was actually rich but felt lean :blink::blink: So... you may have to play with it.

 

Start by lowering the needle. If that help the very bottom but messes up the mid and top switch to a longer needle. I use g length in the kehin. It helped mine crazy. I went from a cel to a cgl. It was sputtering at 1/8th throttle, and slight bog if I just hit the gas. The sputter is what clued me in to rich even though it felt lean when I hammered the gas.

 

Jetting can be crazy. Mine also had the lean bog on top but it was rich. Got worse as I went up with jetting. Lowered the main and it started to pull out of it. Banchetta and I play with jetting every time we get togehter. Glamis was no different.

 

What pilot are you running though. I had to go to a 38 and may have to go to a 35. Finally have some heat in the pipe at lower rpms since I went down to the 38. It's nuts.

 

Anyway, like loco said, what's the jetting now.

 

And don't be fooled. All the circuits overlap more than people think.
