You really need to know the pilot size. I'd bet they are stockers (25)..and they should be ok.

Try turning the air screws in all the way, back them out .5 turns each.

Then....wait 20 seconds for the adjustment to take effect, go for a ride. (make sure the bike is fully warmed up)

Since it's getting cold out my mid-west brother, might be time to bump up the main a size or two.

 

If your bike runs best with less than 1 turn out on the airscrew, you need a bigger pilot. With your mods, though...I think stock pilot will be fine.

I second that on the pilots.Also you may want to try a 1.8 air jets in those stock carbs(1.6 is stock).It will richen up mid and top a little.

Dropping my pilot from 30 to 27.5 and raising my needle to the fourth clip (Toomey Needle) cleaned my bottom up real good. Mine would sputter a little and hesitate.

just raise the needle one or two clips
