Maybe this has already been beaten to death?
So, at least for early superbikes (like my '01 748), the correct timing belt tension sound is at 110Hz (+/- 5Hz). But I read on here that it wasn't the same for Ca Cycleworks belts. I just heard back from them and they waffled! It's a CYA kind of answer:
The tension the belts are set to determines how much force is "pulling along" the belt. Or you could say, pulling down on the cams. With the OEM belts at 110 Hz, to get the same force pulling down on the cams with the ExactFit belts, you set them to 99 Hz. The belts are safe at either frequency setting.
In other words, "Ducati says to set their belts at 110Hz. We think 99Hz for ours but if your bike blows up, it's on you, so you could choose to set our ExactFit belts to 99Hz or 110Hz." LOL!
