Howdy Hi. Mostly lurking these days but popping my head up to access the most respected source of info on such things I’m aware of. Y’all Restoring a race bike back to road use. It has a decrepit yucky amount of that fuel tank foam racers use to prevent sloshing. It’s NOT wanting to be removed. Any suggestions would be so very appreciated as to what might dissolve this product and not decimate the paint or otherwise damage the metal would be even better. I can’t be the first person with a tank full of unruly particles every which where. Input is extremely appreciated. And no I cannot leave it in there. It’s all in little bits and clogs everything! Thanks a million and Ride well! Gabriel 1989 Honda Hawk NT650. We don’t need no silly horsepower 😎 The 1200S MTS Made Me Do Evil Things :0
