Opinions pls: Are these sprockets too worn, and ratio Q.

Hi, everyone,

I'm putting together one of my final (doubtful, but I'm hopeful) parts lists for this rebuild, and am wondering if these sprockets need replaced when I replace the chain.

Also, I've x'd the gears, and am wondering if the current 15x32 ratio will still be optimal for in-town and twisties riding. The motor was seized when I took possession of it, so I have no idea what to expect, performance-wise.

Advice appreciated. Thanks!

Andy

305explr, Forget that rear sprocket,its toast. I think its best to replace both sprockets and the chain at the same time. That goes for any chain driven cycle. I don't have any experience on the trans Xing the gears,but I thought that the 4th gear remains the same. If that is the case then 15/32 would be OK for regular riding but if alittle more acceleration is desired I always liked the 38 T rear sprocket you would normally find on a CL. You will need a longer(just a link or 3) chain. Or if you want to get radical, drop one or two teeth on the front sprocket. It will cause you to suffer on top end MPH but it sure gets you started.

Both are shot and stay with the same ratio. ...............lm

Thanks for the prompt replies, guys. I suspected they were spent. This holiday week is a big window for me to get a lot done on this project, so I'm ready to track down new drivetrain parts ASAP. I've been reading around, and sprocket finding seems to be a catch-as-catch-can affair. Is this the case, or are there suppliers many here use? Western Hills, for example.

Try these guys, I've had good luck with them in the past.

Absolutely agree with Kustommusic's and LM's obs: the rear is ready to be passed on to some budding Ninja. The front would be OK, at a push, if you invert it; but old sprockets will ony serve to accelerate wear on a new chain. I'd always suggest changing the entire sheboodle as a set.

X-ing will leave 1st and 4th gears the same as stock, but will 'close up' the 1st, 2nd & 3rd ratios' gaps, providing a more tractable power band around town and closer ratios for yomping up to 70mph. The jump from 3rd to 4th will be greater, thus requiring red-lining in 3rd to keep the acceleration pot boiling. I'm X-ing mine, as I find the 1st to 2nd gap too great for comfortable, snatch-free town riding.

Hope my opining helps, adding to other info to help you with your decision.
