Most of the time this sort of behaviour can be attributed to a low idle speed. Check that the warm idle speed is around the 1450rpm mark.

On X/R models you need to get a rev counter displayed in the bike's dash to set idle speed, so follow this procedure:

First set engine run/kill switch to 'off' (and ignition to off).

Press both 'SELECT' and 'RESET' buttons and then switch ON the ignition. Keep 'SELECT' and 'RESET' buttons held down for at least eight seconds. The dash then changes to show 'DIAG' in the display. Now release 'SELECT' and 'RESET' buttons.

Press the 'SELECT' button once so 'CO' shows in the display. Now press 'SELECT' and 'RESET' buttons again and hold them down till 'CO1' appears in the display.

With 'CO1' showing, switch on the run/kill switch and start the engine. The revs will now be displayed.
