I want to replace the stock black 2.6 gal gas tank on my 04 KX 500. I've seen a picture of a 2.0 gal 1987 KX 250 gas tank. The mounting screws to the radiator shroud look identical to my 04 500, and it appears it would fit. Anybody know if the 1987 tank would fit? Additionally I added the Delta 2 Reed valve and Moose reed spacer. That was a very good addition it really helped the powerband. One note, I had to file the inside of the Moose aluminum spacer for the Delta reed to fit. Once that was done it slid in with no issues, it also made my KX much easier to start.
