So I Bought a 1986 zx6a that's been sitting for a few years, only have 14k km on it. So I've done all the usual new battery, oil change spark plugs, carb clean. But what's happening is when I am starting it with it connected to my car battery it turns over a couple of revs and stops turning over. You can tell it's still trying to turn over but seems like something is holding it back, I've taken the clutch plates apart thinking they could be sticking together or something but still nothing. Anyone that could help point me in the right direction would be greatly appreciated.
