I've had my shop supposedly adjust the carb twice, but nothing is changing.
Symptoms:
1. when cruising at a constant speed (3rd gear and up), suddenly cracking open the throttle creates a momentary miss/sputter before accelerating.
2. when climbing a long hill in 6th gear, it'll start to cough and miss. Accelerating gets it back, but if I let off and stay at a constant throttle position, it starts missing again.
3. Today, it even sputtered when leaving the line in 1st gear intermittently.
I suspect accelerator pump for #1, and possibly lean jetting for #2. Three just started, so hard to say.
I suspected debris in gas tank so I installed an inline filter long time back, and it is clean.
I recently switched the air cleaner to the 2-inlet style from the single inlet. But the bike had twin inlet when I got it, so I presumed any carb changes would've been done then, but I guess you never know.......
ideas ?
