The belts were replaced in spring '15, and this happened in June '17, about 3,000 miles on them.
I wouldn't think failure from age, but also wouldn't think a defective belt, that would of failed sooner
don't you think?

I understand that checking the tension with the damaged belt will not be accurate. I should have
said that the belt tension & Idler pulleys where not loose or seized in any way and the belt was
not loose on the pulleys. I didn't actually check for proper tension, just that there was tension on
the belt.


I do have a manual.

I have checked in the cylinder with an inexpensive scope, will borrow a good scope and check again.

Again, thanks for the help.

What BRAND was the belt in question??
I have seen brand new "CA-Cycleworks" belts brake in the first month -

Also seen plenty of belts bought at the dealership fail prematurely too!

I ONLY use the DAYCO belts on all my "Rubber-Band Ducati" and for my friends when they require help as well - never had one fail.

and as goofy as it sounds, I have been setting the tension on the last 5yrs or so (about 15 or 20 belt changes on various Ducati) with the "Guitar tuning software" method on my smartphone - works like a champ! they end up not too tight and not too loose, there's a bunch of videos showing how to do this (the app I use personally is called Pano Tuner - it was free on App store)

65 350 Race bike, 67 350 Sebring/Mod, 69 350 SCR, 70 MkIII 350D, 72 450 RT, 74 450Mk3, 78 860, 85 Alazzurra SS, 2001 Monster S4, 2002 Monster S4 (Fake)Foggy Replica, 1999 ST2

generally belts lose teeth when the cam stops while the belt is still trying to drive it.

remove the belt and try to turn the cam. won't turn means bent valves.

sounds like shit's gone south to me.

i set the tension on the old ones just by pulling the adjuster and idler together with gentle force. works well. visual here -

know all wanker
