I bought a 2006 gz250 w/5300 miles, with a broken valve for $100. The top end was laying in pieces in a box. I believe I have all the parts, but wont know until I start putting it back together. The valve had broken and was stuck to the inside of the head about a 1/4" deep. I pulled it out and it left a small hole right beside the valve seat. I believe I can put a little JB weld to fill the hole since it is small and not too deep. I will post a pic later showing the damage to get some advice on repairing the head. I've already downloaded the manuals to get started.
