Two up in the back, one down up front....
on AFAM steel sprockets, new with the chain maybe 8000km ago.
the last few thousand kms, I started noticing odd chain/drive train brushing noises, so I tightened the chain a little. Took the bike for a ride and noticed the chain was tight as hell, so I backed it off again to the proper tension which I thought I had in the first place.
I use my side stand so I may not be adjusting the chain in the best way, but I know a lot of people who do it this way.... anyway, I've noticed that the tight and loose spots in the chain are significant! I roll the bike in neutral and find the loosest spot in the chain, but rolling past that spot, the chain gets super tight. I'm only rolling forward with no weight on the seat.
I'm thinking there is a flaw in the chain, because I'm pretty damn sure I didn't skip a tooth.
I'm also sure that this chain issue caused the plastic chain slider that attaches to the swing arm to wear funny and partially break off. I have a new one on order.
Sorry about the long windedness ... any thoughts?
