Can you be more specific? Off the line? While cruising? What RPM areas?
I would look to clutches first.

Then check belt height in secondary. If using the 8DN belt normally the cogs are about 1mm above sheaves.
Or as high as possible without belt squealing or machine creeping.
You could also use a spring in primary with higher engagement, or shim the stock one.
