What do you mean, "it MAY fit"? Did you install this cap on your Happy Time tank?Take a look at

May fit but depends on tank
I no longer park my mb in bike racks ... Just had bad luck with that ,maybe just me .
Now i gen put a cable around a sign base then a krpto thur crank. Being visable to everyone is the only real theft deterent anyway...
"happy time tank"??? Not sure what your reffering too? Please elaborate.
I'm guessing it works with the stock teardrop/peanut tank?www.ScootUSA.com Scooter* Gas Tanks and Caps I purchased a locking gas cap from here, works great!
