749S DUCATI HOT CAM BELT TESTING TENSION

[@marcusaurileus7984]

never thought I'd find out how much an engine expanded this way

Thanks for posting these 749 videos. I have a 900SS that I’ve had for a while which is really easy to work on. Waiting for the arrival of a 749S from Japan and getting a feel for how difficult they are to work on. Mine will have very low km so hopefully not too much to do other than check belts and change fluids.

Hi Mike I have a 749S here. This outcome is a little counterintuitive. I was thinking as the belts heat they would stretch and get looser, then get tighter when the engine is cooled. Interesting that the 'resting' setting is now well below the original recommended 110 which I assume you started at. Did you ride the bike after the initial belt installation and before this test? If so how many miles?

i think the engine expands more then the belts can. have been riding bike with initial setting . have done the belts 3 times this is the first time i have measured the Hz . normally just set the gap between tensioner pulley the same it was from factory 8.7 mm and 8.8 mm

is it an original ducati belt or a cheap one, maby there is the difference ?
