What's the safest way to remove paint from a 66cc motorized bike engine?

I'm debating with myself about the same thing, it's aluminum casting, and the oven cleaner could possibly be a bad thing, it's hard to say for certain, I wish I had some oven cleaner on hand, I have the spare cylinder from a bunked motor, has black paint on it, I'd willingly test the process and post results... Maybe I'll pick up a can later tonight and put my own butt on the firing line.

Thanks, keeping this in mind, so then no go on that oven cleaner, I can't remember what I've seen it used on, definitely a paint but not sure what type of metal, probably a steel gas tank.

Maybe try aircraft paint stripper, but it might not work on the baked enamel paint. I'd suggest fire, but at the temp needed might ruin the chrome inside the cylinder, which reminds me, don't get oven cleaner on chrome unless you don't want the chrome anymore... That's for sure. Looks like you're not going to have fun with this paint removal, perhaps soaking the part in a container of acetone/gasoline(not recommended)/methol ethyl ketone..

Good luck, paint removal is my least favorite thing to do.

Not sure i would give up on caustic, just be careful dont leaven it on.

I think its mainly getting procedure right.

having gravity on u side helps a lot

I still like ""Hang the bike upside down and immerse the head in an ~ice cream bucket of ~something, as deep as you safely can go.

Thats the hardest bit done."

(assuming it in situ - if not - easier)

put dummy bolts w/ seals in any holes (threads!!!) & float it like a boat in caustic, slop it on w/ a ~paintbrush, hose clean of caustic & soap down a few times

may help to warm the caustic

fyi, never add raw caustic crystals (a must round the house) to hot water, warm the mix after adding.

test on a bit of finning that dont matter much?

I'd probably try fire first, Mapp gas torches burned off every paint I used them on, remember that these are the Chinatown special, they aren't supposed to put lead paint in kids toys but they did it, just like not putting non heat resistant paint on engine parts, he could be (un)lucky and have a cheap paint job of the spray can variety. It could come off with the obvious first choice, acetone.

Brake fluid?

Hehehe...
Just pull you head, jug, and side covers off and put them in a bath of Acetone for a few hours.
It won't do the base but it will prep the parts you want to paint ;-}

Or just paint it a color that DOES go with your shoes and bag.

Hehehehe, I can't help but laugh at that, good one bud ;-}

And dont forget to use crack filler on those unsightly gaps between the fins.
