Is there something called a power  valve on a cr85?

A cr85 has no powervalve.  This is both a good thing and a bad thing.

Having a powervalve boosts the lowend power - that would be nice.  However, having a powervalve means you have to service it - and that's not so much fun.

Of the current 85cc bikes, the YZ85 and the CR85 have no powervalve, the KX and the RM do.
