900 polaris stumble -help !

[Hangtime]

Have a 2005 Polaris 900 in the dealer due to a stumble from 2000 to
4ooo RPM. It feels like you loose one cylinder. Dealer has done all updates and a new ECU. Can anyone help out ?

Thanks much, Hangtime

sounds like it could be throttle cable out of adjustment. does your throttle lever have some play in it? if so it needs to be tightened.

Similar Problem

Mine and a frinds had the throttle positioning sensor malfunction and also the throttle itself malfunction. It took us a while to figure it out with the dealers help.
