No experience of the Cam, but could the plug leads be one position out on the dizzy cap?

Edit - just check Burton Power and they say following for the CVH22

Sports R camshaft giving up to 15bhp increase. Carburettor models only. Adjustable cam pulley is highly recommended.

Power Band: 2000-6500rpm
