I just did a top end job on my brothers new (used) bike-1996 Honda CR250. Started up fine and everything is great except...I went to change the oil and it was kinda grey. Clymer manual says to look at the peep hole under the water pump housing for any signs of coolant or oil seepage. There is none. I just started breaking in the motor and everything else seems fine with no noticable coolant consumption (yet). So whats the dileo?
