What makes you think it's a problem? Our 400's sound like they're revving high too, because they are.

I would guess that the 400's rev higher than the 500's because they HAVE to...

Now, if your belt is slipping, they may be revving higher than normal. It's too bad these things don't have tachs...

 

the autos rev so high. I have a maual and an auto both 400s and the 400 screams

 

I'm guessing the auto's rev higher as they get going, but at 'speed' they ought to be about the same. Or not...? [img]i/expressions/face-icon-small-confused.gif[/img]

 

well the auto can be doing 20 and the manual 40 and that is where it seems to be even in my case. The auto takes forever to get up to speed.

 

The trans type is a CVT = Constant Velocity Transmission. Means the motor revs faster because the belt system keeps the motor in the power band of the engine at all speeds of the vehicle. Want it to not rev so much, get a spring set and modify the clutch timing.

 

The motors are alot different, on the 500 and the 400. The 400 doesnt have the low end torque the 500 does, so the clutch the cvt differently. The springs, weights and cam profile are different , and that keeps the motor running in the sweet spot. Its normal, and almost everyone comments on it, when they first ride the 400.
