I just bought an 01 Polaris predator 90 that didn't idle and the clutch engages at 4500 rpm.
So I adjusted the idle to 1500rpm but it revs high up to 4500 then the clutch engages.

So I need to know before I start tearin into it....the stock belt size, stock spring, and stock weights it uses.

The seller mentioned it had aftermarket springs and it also has an obnoxiously loud pipe on it that appears to be welded up on the end and it has a K&N filter.

It does run pretty good after you get going but I also have to adjust the choke at bit to make it run smooth

I just want it to engage roughly off idle so I can turn the throttle down so my son can get used to it.

Any help is appreciated
