Would like

WHat is it???

Howdy

Just bought a 94 CR 250R That had a stuck Piston.

My ? is on the rt side of the head there is a plug that one can remove with a 17 mm wrench. There is a flat head screw in side that one can turn to a mark with a L at 12 o clock...One with a H with at 9 o clock.

I assume that this changes the height of the exhaust Port.

Is this a adjustment of riding, power  or ?????
raising the port height will give you more r's and faster top end rev. with no bottom?

Thanks for lookin
