You can get the ECU reflashed to higher rpm limits... It's expensive...

 

or you can luck up and find someone selling a dyntek or a procomm for cheap...these raise the limit only 500rpm over the 6500 stock..anything higher than 7000rpm on a stock engine is asking for trouble..

 

Yeah the stock crank will twist over 7000 RPM unless u pin and weld it. A dynatek would be the way to go but they not cheap either and u won't gain much more MPH.

 

Isn't there a speed limiting spacer in the primary clutch that can be removed?

 

Thanks for the info! This is my first EFI I had a grizz and the dynatek was awesome just didn't know if there was any for the efi's and if it did the same! I have heard about the clutch thing has anyone done it to there's and what did it add any Mphs?

 

I appreciate your need for speed, but you also have to remember that a RZR will do the unexpected at very high speeds. Things that might ruin your day. We have ridden at WOT for 4 miles up a gravel road before. It is scarry. One wrong move, and it will go completely out of control. The brakes are fair at best, and the trail type tires are worthless for stability at those speeds. Have fun and stay safe!

 

forgot to post back - the 2010 had no speed reducing washer they eliminated that in 2010. Went with the dynatek FS ignition and it took care of the rev limiter was a sweet buy!
