strange revs- high and wont return smooth and slow to drop

[Ric]

when i rev it goes up and stays there and then drops down really slowly

basically sounds like im ragging it of a blip of the throttle

bit worring, assuming the change in heat has summin to do with it

Lower the idle?


You HAVE to come on sunday, no excuses.

probably dirty throttle cable or the throttle itself . wd40 inside the cable , clean the throttle and lodging

Sounds like your carbs are out of balance, (more than one carb)?

Could be an air leak between the carb(s) and inlet manifold. My bike did this, and that was the cause

Possibly your throttle cable is rusted up and so get a cable oiler device + a tin WD40 to help free up the movement of the cable.

id tighten the cable too much last week, dunno y it changed now

[Kye]

Carbs are probably out of balance or an air leak in one, my ZXR did that and was fine after balancing the carbs
