I doubt if it will be critical if you went several thousand miles over before checking the valves. My dealer in Salem, OR said not to bother with the 600 mile check and that they should be OK to 12000 miles. I'd be surprised if anyone had to adjust the shims. I've had other bikes with Rotax engines and have yet to adjust the valves.
