I think there are 2 threads going on here the OP who put the video up ( Markie)isn't the same is the other (tefer) who is having trouble with his exup as well.
On a separate but slightly related note , I think some confusion has been had over the years with Yamaha exhaust valves is some of us of a certain age remember the YPVS system which made the servo noise every time the ignition was switched on to clean itself ,whereas as correctly put by robbo the exup system doesn't work that way.
