Who can share 250 pp port timing maps?
« on: April 29, 2019, 08:23:29 PM »
Anyone have any port timing maps for a piston port 250 ? I guess CR250M, TM250, KX250 or Euro 250's?

I'm really interested in what the range is of what works. TIA.

Or even some measurements from the top of the barrel to the tops & bottoms of the ports, please :-)
