Has anyone heard bad things about running fuel with valvtect in fourstroke yamaha's? I have replaced the fuel filter on the boat with a highperformance 10 micron filter and the gas gums the filter within 3 minutes. (running twin yamaha 225 fourstorkes)
Have twin Yamaha f225's new this year. Port engine is a champ runs great, starboard has been problematic from the get-go. Runs rough at idle and has burned a few injectors. Injectors have been replaced twice and still runs rough. Sound coming out of smoke hole like it's misfiring. Also...
