Power Valve Notes on the Early-90s CR250
The 1992 CR250’s HPP power valve system is critical to the bike’s powerband character. Clean the power valve at every top-end service by removing the cover, extracting the valve plate, and cleaning all carbon deposits from the exhaust port and valve surfaces. Inspect the governor mechanism for free movement. If the valve sticks open or closed, clean the bore and inspect the spring before reassembling. A properly maintained power valve makes the difference between a sharp, usable powerband and a sluggish, unresponsive one.
