I have a yz14s battery from gsyuasa. If I crank the bike more than three times the battery just goes flop. It's supposedly a new battery I got from dealer and paid $200 for it. They said it's the best one they have in 14 amp for my 83vt750. But seems like I should get more than three cranks out of it which is needed on a cold day especially if it stalls first thing. Opinions on battery or maybe the starter is drawing too many amps??
