Belt Change Tuning Frequency

[bazz20]

yep dragon that one went over my head , i hooked my bike up to the mathis machine , thanks too the local ducati guys , too test two theory's arfter setting at 110 hz tried the twist test at 45 but that was hit and miss then reset the belts and tried allen key on tensioner pulley and a 3 mm allen key was a nice fit

I was steered in the direction of this site to download a "Computer sound meter, guitar tuner" that could be used to tune your belts. 

Too much like hard work I reckon, the allen key method works just fine thanks.
