So today I put in a new battery fully charged, when I try to turn on the engine, it starts but will not stay on for less than a minute. I try to give it some gas but the engine still wants to shuts off and I continue to do that several time and each time it shuts off. The bike has been sitting for quite some time therefore the old battery was shot so I had to buy a new one. Does anyone have similar problem or any idea how to fix? thank you
