I noticed that you spec sheet says 2 valves. Trust me I spent half a day lapping my valves with a wooden lapping tool there are 4 valves. 2 intake and 2 exhaust.

I have noticed many errors in magazines especially last years motorcycle buyers guides as to the number of cylinders and valves on the GZ 250. One magazine actually had a GZ250 image with the 650 cruiser description. I thought that was funny because the GZ is so obviously the better choice :-)

Any body got any old engines especially top ends. Rocker box valves. Mines running but eventually it will need a new one :-)
