I have an XMR 570 and I turned it over in the water. Not bad and not for long. I’ve done it before and was able to get it going after the standard oil changes and spark plugs, air box ect... but this time I have done it all and it will turn over and the RPMS get to about 300-400 but won’t start. What am I missing, or is there something I can do. I have new plugs and charge the battery every time till it says low voltage. I have also checked valves, and pulled exhaust to drain water from it. Is it something stupid?HELP PLEASE!!!
