I'm from your brother's school

I had the opportunity that you had, but given the circumstances I passed and only replaced the tensioner guide and chain rail. My chain appeared in perfect condition, much like Capn's.

I figured, if it aint broke, why fix it? Too much at stake to mess up, and that crimp tool is a pain in the a$$ to find and is way too expensive to rent/buy.

As Sixto said, in almost all likelihood, only foreign matter will cause it to break (catostrophic tensioner/chain rail breakage), NOT the chain failing itself.

It's your call, but if the chain looks good, I wouldn't fool with it. It's a tricky replacement.

Good luck!
