Just bought a 2015 Ninja H2 and rode it for about 20min in 38 degree weather, rode perfect no noises etc. Oil Light came on first shortly followed by the high temp warning indicator. Immediately pulled off the road and shut it down. Let it cool for about 30 minutes and when I tried to restart it it now just slow cranks? Previous owner said the bike never did that too him(could be lying) he said check the battery, would a dead battery cause these issues? Bike has less then 900miles on it.
