I understand what you are saying about the sprokets wearing and I did check mine carefully. I didn't clean the chain as often as I should have, and given the environment I live in, I need to clean it even more, probably every 100 miles or so, I was pushing it sometimes 400 to 500 miles between cleanings, just giving it a squirt of lube instead of a deep cleaning because it 'looked' ok. That was my bad. I am also a person who likes to put their bike to work, I ride it hard, and take it on the track as well as street running. It gets its workout.
Maybe I didn't need to change it quite yet but it makes me feel better that I did, plus I compared my original sprocket to a brand new one and the wear was negligible, no dragon or bubba teeth on it. The chain and sprocket is supposed to last what? 15 to 20 K miles? I wasn't even half that yet, so am comfortable just doing the chain, however do have a new set already on hand of everything for the next change out.
TBH I have an entire wheel and sprocket change out, for when I DO take it to the track, instead of fricking around trying to remove tires from rims, reinstalling, balancing bla bla. I just change out the entire wheel, front and back. it's a 20 minute job .vs. an hour and 20. If I get in a jam, I can change stuff out with parts on hand.
As for Torque values, I have to look, I have it written on my tool box notebook, I don't have them memorized. I have also head some people say that when it comes to the rear axle, torqueing them to the specs the OEM states, can mushroom them after time, that going a bit light won't harm, in fact might be a better idea.
One thing I do notice. The holes for the chain guard to bolt down, they get crunchies in them real easy, have to keep them very clean or you'll be chasing threads. I heard someone say they used stainless or titanium screws? While that will keep the screws from getting shitty which they DO, on that note, do you want the swingarm to be your sacrificial surface .vs. a 10 cent screw? Just some food for thought.
