So I have ran into a problem and i think i know what it is but i want to hear what other people think. So i was in a mud hole when my Can-Am stalled out. After digging into it a found that i had water on top of the pistons. Removed the water. I also found out that i had water in my crank case and in the oil. Drained the oil removed the water on the cylinder head and put new oil back into the motor. Now the atv cranks just fine no problems. Drove it around for 30min or so and didn’t seam to bog down and felt like it had as much power as it did the day i bought it. Heres the problem. After riding around for 30min i turned the atv off and then tried to re-crank the motor and couldn’t get it to turn the motor over. Hooked a truck battery up to it and it cranked up. I checked the battery while trying to crank it and it held 12v so the battery isn’t bad. If i let the motor cool off completely then i can restart the atv with the original battery. I also changed the oil twice after finding water in the crank. No metal shavings or anything unusual found in the oil.

I think the starter got water in it and is failing on me. Someone else told me the crank bearings were going bad. Hard to believe because there isn’t any vibrations or knocks.

Tell me what y’all think.

thanks,
