I have come to the conclusion that I need new chain and sprocket kit for my bike. I was wondering what everyone seems to be running and the results of the products. I was looking at some some supersprox but can't decide. I want something that looks pretty cool but I want the rear sprocket to be black I think. When I'm riding my bike at a steady rpm it seems to jerk. And I think it may be because my chain is stretched and I had to re-tighten in twice in the last 2 weeks. It seems like when I have it on a stand I get the chain to the proper tension and then rotate the rear wheel a 1/4 turn then it's loose then another 1/4 turn then back when I set it at. Idk but it's starting to annoy me. Any input would be greatly appreciated but I just want to replace it all I think.

This is from my manual for 08 09 zx10.
••Remove the chain cover (see Drive Chain Removal in the
Final Drive chapter). ••Rotate the rear wheel to inspect the drive chain for damaged
rollers, and loose pins and links.
If there is any irregularity, replace the drive chain.
Lubricate the drive chain if it appears dry. ••Stretch the chain taut by hanging a 98 N (10 kg, 20 lb)
weight [A] on the chain. ••Measure the length of 20 links on the straight part [C] of
the chain from the pin center of the 1st pin to the pin center
of the 21st pin. Since the chain may wear unevenly, take
measurements at several places.
If any measurements exceed the service limit, replace the
chain. Also, replace the front and rear sprockets when the
drive chain is replaced.
Drive Chain 20-link Length
Standard: 317.5 ∼ 318.2 mm (12.50 ∼ 12.53 in.)
Service Limit: 323 mm (12.7 in.)

Thanks KB. And blink, gosh damn I bet your bike is a beast geared like that. I think that would be way to much for me.
