Surging at cruising speed
OK maybe you guys can help, I have an 04 klr650 . The bike runs perfectly fine at idle and at wide open throttle. now cruising in 3-4-5 gear @ 2500-4000 rpms the bike surges, no that you can see in in the tach, but i can feel it in the seat of the pants, now when its happening i move the choke lever over to full choke the surge goes almost away, not completely gone but close. i have the .22c mod, uni filter, L mod, snorkel removed, and the pilot screw under the carb set @ 2 1/2 turns out. Also too the muffler apart and got rid of the center and got rid of the "tweet"
now i tried putting the snorkel back in and put the screw back in 1/2 turn to 2 turns, and its still there.
The bike just turned 5100 miles with no other issues.
I think its running too lean but when i tried to run the screw at 3 turns its the same.
