The power level did wake up on mine over the first 80 miles. At around 40-45 on the odo, the engine just got, well, more lively, for lack of a better term. At 82 miles, it's wide awake. And mine will stand right up if the throttle is nailed, high or low. I did have to adjust the throttle cable to get rid of the nagging stall-off-throttle condition, but it took 2 minutes to correct. Such an amazing machine.. just have to get rid of the champion plugs now. And get a K&N. And maybe Bighorns.

 

How did they determine that Hot? Reason I ask is I've got this noise at slow speeds that I can't seem to isolate. It sort of sounds like a brake shoe is dragging, but I've had all four off the ground and can't reproduce it for the life of me. When cruising slowly, say 15mph I can hear it coming from the rear end area. It's too faint to hear with a helmet on. Probably imagining things.

 

Bitter, So you really think the champion plugs are holding it back? Kind of getting off topic here. Maybe I'll start a new thread on this.

 

Not so much holding it back, I just really don't like Champion spark plugs. I think there are way better brands out there. NGK, for example

 

The mechanic told me they disconnected the shaft to the rear end and used it in 4x4 and the sound was not there as loud. The rear end made a howling sound under power, but went away when coasting. My drive line still makes some noise but I think that's normal. Either way good on Polaris for changing the whole rear end and not just fix it. The gears my have been pooched from driving with them so tight.

 

OK. Yeah, I'm not hearing any kind of howling sounds. Glad to hear you're good to go.
