I have twin 2007 DF250s with approx. 250hrs on them. They started out getting around 1.8 - 2.0 miles per gallon avg. Now getting 1.5 or less no matter how I run them. Dealer checked them out and says compression checks good but suzuki factory rep. suspects carbon buil-up on rings caused by long periods of idling. Recomended a shock treatment of Yamaha Ring Free then continued normal dose treatment from now on. We troll a lot and also overnite fishing deep water oil rigs and idle around all night. Anyone else experience drop in fuel economy? Ideas?
