I also adjusted my chain yesterday. Taking into account that the chain will tighten a little bit when tightening the axel nut, i just left a little extra slack in the chain before tightening the nut. And voila, perfect slack. I measured 26 mm of free slack in the tightest spot. I measured the rest of the chain at like 10 different spots. Just wanted to make sure i had it right.
The other spots i measured had about 29 mm of free slack, so everything is whitin specs. Also tried pulling the chain at the back of the sprocket (3 o'clock), like Joe mentioned in another thread, to check if my chain is worn. Couldn't pull it out more than 1 mm so the chain still has a lot of miles to go.
I also didn’t use the marks on the swingarm to align the rear wheel, as they are notorious for being a bit off. I used them as an indication and I measured everything with a digital caliper to align the rear wheel perfectly. I also checked if the chain goes over the centre of the rear sprocket, and that was the case.
Funny thing is, when I let the dealer service the bike at the beginning of this season they took the rear wheel of for some maintenance work. When they put it back on I think they did not align it perfectly (it was good according to the marks but still a little off I think), cause when I rode the bike and let go of the grips, the bike used to pull a little to the right. Now that I aligned everything myself the bike keeps on going strait as an arrow when I let go of the grips. So all is good now.
I'm still running the stock chain on the bike but i want to start looking for a new chain and sprocket set for the next season.
