Nice, but where did you find the countershaft bolt torque?
I'm not saying you're wrong, but I couldn't find it so I emailed Stark and they told me 80 Nm.

BTW, I just changed my countershaft sprocket, and it was "loctited" at the factory.
Wouldn't hurt to put A LITTLE heat on it when removing.

I'm glad you pointed this out. I actually could not find that spec anywhere and resorted to my Ktm 300 spec just to give myself a ballpark figure. Thanks for catching this and correcting it. There are also some contradictory specs like on the chain tension. It says to use the 3 finger rule but also says the range is 25-32mm. I don't know about you but my 3 fingers are way bigger than 1.25". Anyways, I am pretty sure that was the only one on there I had to take a guess at. I'll change it to 80Nm. There are obviously a bunch of other specs I left out from the manual as they aren't typical things you have to work on and can be hand torqued pretty safely.

Here is a 3D model of the Varg chain slack gauge I made. Makes it easy to adjust the chain to specifications. Pull the chain tight by pushing down the bottom, and slide the gauge along the swing arm until the reference (0 point) touches. Release the chain and then tighten the chain until it goes over the second level but not over the third level.

Thank you for sharing the file, I converted it to a step file so I could open it in my 3d software.
Could you provide a photo of it on the bike, as I'm a little confused by your instructions.
Thanks!

It goes where your "3 fingers" would go, except it is more precise with the Reference level:

Thanks for the photo, it is worth a thousand words!
Not trying to be annoying, but why do you need the “reference” step?
You basically have a “GO” and a “NO GO,” isn’t that all you need?

The reference level represents 0 chain deflection, that tells the gauge is in the right place. The first platform above that is the minimum chain slack, and the top platform is the maximum chain slack.

Once you set the slack correctly the bike runs quieter with no chain slap.

Got it, thanks.
