I am changing my belts on my 1200s tomorrow, new exact belts will be delivered today so I will have all the bits I need. My only question is what frequency should I set the belts too?
I have read somewhere that Exact belts are set to a lower frequency than standard but can't find it anywhere. As far as I can remember standard belt are set to 115Hz whereas exact belts are set to 100Hz, am I correct in my thinking? Also what torque setting should I use on the tensioner nuts?
