Gates isn't a bad belt but the G series is for ATVs not UTVs like the Z Force. You want the C series.

Thanks for the info. The people who owned it before me had the gates belt put on. I read in the cfmoto workshop manual that the specs for the standard belt are 34.5mm as standard with a service limit of 33.5mm.
According to gates website the Gforce belt fitted was 36mm, I measured it with a vernier and it's somewhere between 35mm and 35.5mm. Could this be the cause of the sometime jerky pulling away? Time for a standard belt I think, and possibly new rollers

As the Z800s have wet clutches and the belts are in direct contact all the time I would think not unless there is some bad glazing on the belt. Jerky take-offs are more likely a sign of warn wet clutch shoes or in mine's case, a weak throttle peddle return spring...yeah I was surprised too but if you have to hold your foot up because it's weight alone depresses the peddle, its too light and makes for jerky take offs and bad foot fatigue riding.
