Nothing precise about it.

You should have the tool needed in your small tool pack under the seat... if not, a flathead screwdriver + hammer will work.

There is a nut on your swingarm close to the rear sprocket. Loosen this, but do not remove.

That's what locks your chain tensioner in place. Now look just next to the sprocket, there will be a collar bolt that looks like what is on your rear shock for the preload, but only one of them, and it's much larger.

Turn it, it doesn't take much of a turn to tighten the chain. Turn it a little, check slack, when it's good tighten the bolt back down to lock it in place.

The SSSA bikes like slack to be a little on the loose side of things. Always better to be a little too loose than a little too tight.

 

Ya that is pretty much it. The special tool will look like a big spanner wrench and there is a separate handle for it that goes on it. Also you adjust it with the bike on the sidestand and remember to find the tightest spot on the chain too. The manual details it out so should be pretty easy.

 

Here is the tool you need

 

Don't forget to use the handle that slides over it. I tried using it just by itself the first time and thought why is this so hard and who would make a tool than you can barely reach when it is on the adjuster? Sometimes I am a bit slow. lol
