Polaris 900 Speed problem

[RMKrick]

It should max power at 7600 to 7800 i run my RMK at 7800 max

Also you should have the 1115 belt not the 080 belt. Stock weights re 70 and red black spring.The other belts will not handle all the power make sure your chutches are alined and your belt sets up for the 115 belt..

With the belt off does it rev higher or 6 grand?

Don't do that you can really over rev your motor with no load on it.

 

[RMKrick]

Well dont hammer it but see if it will go past 6000 if so it is your clutches that is all..

Take the drive clutch off the sled. Buy the correct weights and springs from Pol. Take out whatever the previous owner put in there - which probably contributed to the original engine trouble - and put it back to stock, or whatever Pol recommends. Put the clutch back together and use the right belt. DO NOT RUN THE ENGINE WITH THE BELT OFF TO CHECK TO SEE IF IT WILL REV OVER 6000. Trust me, it will. And it will give your nice new motor an excellent opportunity to wreck its crank.

X2 on what grubb said also if its a new belt make sure the tension is set to spec. i believe its an 1 1/4"
