  • 12.5-1 compression

    Hello. This is my first seadoo. It's a 1990 sp. It has burned a hole in one of the pistons which I am addressing now. My question is , am I going to have to run racing fuel in it ? The head on it is a ocean pro 12.5-1 swirll chamber head. Any help would be appreciated.. Thanx
