The pump on the 600HO has been changed to a 35-1 ratio at wide open where the old 600 was 50-1 wide open.
My 600 used a quart to 75 miles and after 300 miles I started leaning it back.Now getting 135 mi. to a quart.
I ran my 500 Ski Doo at 190 miles to a quart and had no problems with over
10,000 miles on .
