He he J, that's rude! Don't take any notice Hero stoic bloke. Well, not much anyway...

Seriously, as I've said, this mod of your is, long-term, going to save numerous

a) Countershaft bearings due to overtightened chains
b) Crankcases due to busted, overtightened chains
c) Derailed chains, possibly causing damage
d) Amounts of money due to relative lack of wear and tear on external drive
components because of properly adjusted chains
e) Shortened lives from owners stressing about whether the chain is going to
dismount at a critical moment.

Of all the things I've done, or am going to do to my bike, this is the best, and probably cheapest, mod.

The reason I'm gushing on is that eleven years ago my '96 Tenere was assaulted by a busted chain at 130km/h, in a remote area 600km from home, in the dark and drizzle. The resulting damage was annoying, but not as bad as it could've been. The engine went from >5000rpm to zero in a nanosecond as the chain bunched up around the drive sprocket. On the way it ripped off the chainguard, smashed the helmet lock and busted the alloy left side of the carrier. The crankcase survived with a hairline crack which only wept oil very slightly. And the engine internals survived totally. Not even a bent countershaft or twisted crank. That was one tough motor, luckily for me. I continued thrashing it for another year or two, and it sounded like a new one when I sold it.

A properly adjusted (even slightly loose) chain would've avoided the whole issue. It remains the only O-ring chain that I've had break in some hundreds of thousands of kilometres of dirt riding, since everything else had a rear chain guide and I could run a nice, loose chain (within reason). I've had chains wear until they started spitting off rollers (on work bikes), but no breaks except for the old Tenere.

Thus I owe you a beer, stoic bloke. If the chain breaks it won't be due to overtightening. Cheers, mate.
