I had this minibike a few years ago and let my Uncle have it for his grandkids. Well grandkids are on to dirtbikes now so hes cleaning out the shed. Engine that was on there was an old 2hp Briggs. I took it off and put the 3hp Tec I have been messing around with but its too small for this bike(This is a BIG minibike) Anyways I love the gas tank and plan on getting that functional again. I still have that 6.5hp Honda waiting for something hmmm....
