[Flagstaff Fury]

I have an '03 125SX with a Regina chain and Renthal sprocket. As of now the tension on the chain sits a little loose and was just wondering if it were better tighter or more loose. Thanks!

Better loose than tight I supposed but why not adjust it to factory spec.?

I'm not quite sure what the factory spec is. I got the bike without a service manual.

check measurement in several places as they don't wear evenly.
