they finally have the EFI on there and it makes some good power and they talk about how much fuel its getting. its a bad boy.. :beerchug:



look with their single pipe ot pulled all the way to 8200 and only lost 1 horse from its peak at 8100, thats some big top end speed, the ysay it was like having a top speed gear in it. i wonder what the difference if any would be between the twins and their single pipe setup??
that thing will fly like that, 8200. thats big speed

Yeah.. Big speed, major loss in torque at the lower RPMS.

Enough with the SPAM

ya but the loss of the torque would probably help you hook up better. and then add the reeds and other stuff to get some back also..

plus still more torque the a modded F7 and they run great anywhere on the ice, trails or gras drags. they had the top speed in the big moose dealer shootout, but the zr ran 11.94 et in the 1/4 and the closes to it was the F7 at 12.26 but it lost mph in the 1/4 99.50 and ran 100.5 in 1000 foot. the zr900 went 96.38 in 1000' and 97.14 in the 1/4 mph. and they both along with the F6 were listed as the fastest and quickest sleds, the zr took it all and they said was the quickest sled ever at the shootout with ski-doo and polaris and yamahonkie there to..ARTIC CAT'S RULE :beerchug:
