7K RPM. Continued operation at 7k or above requires better valve springs.
There are many choices and some of them are pretty stiff, resulting in higher rates of wear on intermediate shaft gears, chains, sprockets, idlers, cams & rocker arms.
One can easily see the consequences of using (too) stiff valve springs so such decisions should be taken very seriously.
