I would strongly suggest you contact Motortrike immediately and request assistance. I'm not sure why you state the switch is not the problem. If it wouldn't turn off, how do yo know? Some of these air systems use higher pressure in the 140 psi range so I wouldn't worry to much about that. Usually, these systems have a high pressure cut-off switch, or a timer that will only let them run for a few minutes in case of a major air leak so the compressor will not burn up.
