MRZ,  I rode Wille's 600 up in Canada, and it has that instant snap feel from the Bikemann mod, with the clutch spring he installed. It feels like riding a motorcross bike. Instant snap, very fun in the trails. Top speed, well. I never got a chance to really run it on a lake, but it feels real quick for sure. I at the time had a 02 XC7 and it felt snappier than that did, and alot more fun to ride. But Willie will give you more info on it than me. I bought a new dragon 600 switchback this year, because I felt the gas mileage will be better for sure and the power is at the very least the same as my 02 XC7, and alot more fun to ride. I am doing the Bikemann mod myself along with the clutch spring kit. It is a cheap way to get alot of fun!

willie;; In your testing what does the sled run at for rpm to get the max. result???

7900-8100 max

Didn't try the 11-64.  I don't think they will work the the set-up I gave here.  Use the 10-64 with EPI maroon and you will have the best set-up I've found...

Really???, hmmmmmm.  I should have waited until next year to get a new sled.  Do you know if the chassis will be similer to the current chassis?  Any chance of Polaris coming out with a Direct injection for 2010? Fine tune that and maybe see a 130 Hp 600 stock. Maybe a new primary clutch? 

 Willie: When the P2 clutch comes out in 2010 for the 4 injectors, it will fit my 2009 600 4 injector, right? 

Willie, I have a Fusion 600 136 with the cobra track, Bikemamn pipe mod. I was wondering will the maroon with 10-64s work or should I try 10-62s, I also have stock gears. Thanks, ppolaris
