Okay 05 f7 efi. Snapped the crank a month replaced crank new rings 2.5 timing key. Now sled wont go over 60. Figured powervalves I looked at the pic in FAQ for yamaha srx and figure the bevel should face exhaust not piston. So he had them in wrong turn them around same thing. Fired it up noticed servo motor cycled then went back to closed position right away. Arctic chat is so hard to navigate. So maybe someone here knows cable adjustment and powervalve direction. Or any other tips. Thanks!

I don't think the powervalves alone would limit the speed to 60. I think you have something else going on. Get rid of the timing key & try it. maybe the computer doesn't like it?
That's what we are right in the middle of trying
I'm I right that the valves should be oriented the same as a yamaha?
I would start with looking at the internals in the primary clutch. almost bet on it.
Weights and rollers.
Weights and rollers.
The clutch was good before the crank busted
Well the ignition key was unplugged. But it's bedtime check tomorrow if that was it.
Well it was the can he got it used and it must not be for his sled. Funny cause its just straight thru like a glass pack.

was it a d&d by chance? or rumble pack/mbrp?
probally ethanol related. we avoid ethanol. So has not had a issue yet but i will mention it to him.staggs65 said:
It was used so I dont know what type. Funny thing is he traded his buddy who had an f5. He thought because it was straight thru wouldnt matter. Needless to say they traded back.mopar1rules said:
