The kits are located above the right foot stirrup. To access it, remove the side panel (no tools required, simply pull the R-clip fastener located by the upper A-arm, then pull back the front portion of the panel, which will bring it completely off the sled).
With the side panel removed, locate and remove the zeus fastener holding rear of the bellypan and the knee-console.
Voila! The tool kit is tucked into a recess behind the chaincase.
Here are the tools contained in the kit for my 2012 Arctic Cat F1100 NA. I noticed that the gold torx tool is magnetized…nice touch!
UPDATE: Lots of comments from owners of 4-strokes who didn’t get the large flat washer in the tool kit, that’s used to help spread the driven clutch to ease belt-changing.
The reason it’s not included is because it’s not needed to open/spread the driven sheaves on the 4-stroke models.
However, the flat washer IS required on the 800 models.
