    Need tips / tricks on paint removal

    So this Yamaha engine has the most evil coating on it. I got a quart of paint stripper at Home Depot and brushed it on. 20 minutes later it had just barely blistered up anything. My question is what the heck was this engine painted with and whats the most obnoxiously evil paint / powder coating remover out there? I want the badddest of the bad to slop on this engine. Probably restrip the bottom and start from scratch if I can find the one that eats this stuff off the engine.

    NOTE: I had a small wire wheel for the Dremel and that just barely scratched the paint so that option isnt a good one either.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

    Try lemon gin. We used a hot lacquer years ago on furniture. Polystrippa just sat on it for hours and did nothing. Lemon gin cut through it like a hot knife in butter.

        Sounds like great paint. I want some. I've always wondered what these OEM's used. My KZ engine was painted before machining and the paint inside is rock solid. Almost impervious to chemicals.

        If I were you chuck I'd just rough up the old paint and shoot your new paint right over the top.

          Have you tried aircraft stripper?

          Do Not Let This Contact Your Skin. It is some wicked stuff. You can get this at most auto parts stores.

            Not sure if this is some kind of canuk humor or not

            I have always been nervous to cover old air-cooled engine paint with more paint because it might reduce the motors capacity to scrub heat... is this being overly cautious?

              The OEM paint is very thin. I wouldn't worry. It's almost like gunkote more than paint.

                Yamaha uses (or used) an epoxy on the engine as opposed to paint, not sure what it takes to soften or remove it.
                1980 Yamaha XS1100G (Current bike)
                1982 GS450txz (former bike)
                LONG list of previous bikes not listed here.

                I identify as a man but according to the label on a box of Stauffers Baked Lasagne I'm actually a family of four
