Hey guys. I was going to check the fuel level in my 89 TRX350 when I couldn't get the gas cap off. It has the little plastic "lock/open" lever on top of it. It feels like one side isn't opening when I flip the little switch thing. I didn't want to just pry the cap off for fear I wouldn't get it back on. I tried to find a new cap online in case I just have to break this one to remove it, but they don't seem to be available.

Help? What's a fellow to do?

Hey Gray. Remove the knob mounting screw pull that black plastic knob from the stem and see if the knob is stripped out. If not you can spray some lube in the top of the cap–use some vice grips to turn the stem.

Usually the cap can be refreshed with the lube—my knob was cracked so I loaded it up with epoxy and it has held. Otherwise you can buy the minimum $40
