Sorry Gary, the trike is put away for the winter, otherwise I could answer that for you! Man, things are moving right along!!
Have you considered about 5 to 6 PSI of air pressure to pop that dent in the gas tank?? I wouldn't go any higher but that should be all the pressure you need.
Right now I'm considering looking for a 1700cc Vmax motor for Goldie and a landing gear setup...
