So im losing coolant, twice now topped of ive lost about 1/4 of the coolant. The oil both times wasnt grey or lighter at all really. My son said he saw smoke for a second but i had just went thru a puddle. Riding at the track yesterday i lost the same amount again and oil was fine. Do I check for bubbles while running with the rad cap off? Starting seems ok still not to bad. Runs fine no smoke what so ever. I am running water wetter with regular not distilled water. I meant to drain it i know itll corrode.
