I forgot to document what I did for the tank.... sorry Bob... lol
In case anyone was curious, I used the stock CRF250R tank. Took the cap off, set it upside down on a stand and proceeded to heat the crap out of it with a heat gun. Concentrating on the 9 and 3 o'clock positions. After 3-4 minutes you can see a color flash move across the plastic.
I took the handle end of a hammer and pushed the hump in. The tank wanted to move back to its existing shape, so i re heated one side, pushed and held it in position while it cooled. then moved to the other side.
While I was pushing on the fuel spigot side, the seem split open!!! I thought I had ruined the tank. I applied more heat and was able to reseal and actually overlap more plastic where it split. As it turned out, the side I split looks better than the side that was just melted. I had some Heat tape in the shop, so i covered the bottom of tank just for looks.
I pressure tested the tank and filled with gas. 2 months, several tanks of fuel and NO leaks! I have clearance for a standard BR series plug.
