2018 Kodiak 450 -- what is this part???

[chuckufarlie]

So I rode my 2018 Kodiak 450 through a bit of a puddle and got water in the ultramatic casing... drained the water but the quad still fails to reach top speed so I figured it's time to pull the sheaves and clean them out.

When I pulled the primary sheave off, this rubber piece fell out that I can't find anywhere on the parts diagram nor where it might have come from. Any ideas?
Note, it looks worn down on an angle, so wherever it came from it might have been jammed in the sheave and that could have been what was preventing me from reaching higher speeds.

Any help is appreciated.

Have you looked the fill plug cap where oil fills in ? Maybe the bottom  half of that plug?

I'm thinking this is some kind of damper, just not sure from where.

It is almost identical in shape and size to the dampers on the seat, but all four dampers are on the seat and they aren't angled at all... search continues.

Is it a soft rubber ? Plastic ?

Soft rubber.... almost identical to the rubber dampers found on the bottom of the seat, but this one is angled a bit.

I honestly think someone put it in there unless you are the original owner.
