Question:
gurgles and will only pull about 60 miles per hour.
I’ve turned in the air and fuel mix screws and turned them out only half a turn where they were about one and a half turns out. Its made an improvement. Also, the plugs were rather black before so do u think its getting too much fuel at higher revs and not enough air.

Answer:
If your Z650 has K&N air filters but no jetting, you are short on fuel supply at higher RPMs. Check out Carburetor Jetting, page 1
and page 2
to find out what size main jet you have, then increase the # by 5.
Take it for a test ride. The holding back that you are
experiencing should lessen.
