Whats safe with YS

How high can I spin a YS-Trim? I know that the specs say 65k but what are some of you spinning it to. TIA Chris

I have safely spun mine to 71k..........you wont be able to get much higher than that with cogs as the belts cannot take the tight wrap of the smaller pulleys. my passenger side unit had 200 passes or so on it when I took it off to go to the drivers side, 2 years at 71K never hurt it. The driverside was spun at the same rpms for another 20 passes, again with no problems. dont be afraid to spin it, its a tough lil bastard.

Thanks Spence.
