Chain was stretched to the max, tensioner looked to be fair, but what the hey, may as well while it's down. Working very well. Good service & fast delivery from CBS, as usual.

Looks like a good exact replacement of the original. Good price

I didn’t think I would be able to find a replacement for the cracked and bent original I found while renewing the clutch. Fits perfectly and the primary chain can be tensioned properly. A bit pricey but good stuff.
