Hey guys, How can I remove all the ugly melted piston material from my cylinder? I hope the cylinder is not ruined but can't tell until I remove all the material and hone it out and measure it, where do I start?

That don't look pretty...

you could try some muratic acid. Using a eye dropper, place drops of the acid on the smeared aluminum, this will eat it off and not hurt the plating, let it sit and bubble, it will do the work, when it all turns to grey bubbles, wipe off with a rag and repeat if needed till its all gone.

wear gloves and dont breath the vapors from it bubbling, its nasty stuff, it eats aluminum, so dont get it on anything you dont want gone, you can protect areas you dont want touched(aluminum) with a smear of grease!!

I guess I should have told you guys, i live in the middle of nowhere with no hardware stores or anything like that here, closest one is 300km in each direction :(

And this acid, if i can order in some, will not affect my steel sleeves either?
 
Wow you do live in the middle of noware..LOL


I'm going to say no on the steel,but i have not used it on it eather so..

you may ba able to just hone it out,,but it may smear the stone..
 
Rob, we got some of that muriatic acid at the shop that you could have or use. i know i saw your avalanche and trailer in town are you back in churchill now? i know someone going across wednesday.
 
It can also be found at building supply/lumber yards. It will not hurt the liners.
 
With that acid it will take forever to clean that kind on mess. Just bore/hone it again cause it's steel sleave.

Edit: Actually, do you have wiseco pistons? With wiseco's you need good clearance with iron sleeve cylinder. I think it would be good to get used nicasil cylinder.

Wear protective eye wear when using muratic acid. Not sure if it will eat that off? Good luck.
 
I just used some sandpaper and sanded it off, honed it out again and it turned out good, just took a lot of time...... thanks guys, again no acid mear me, i live in a small private company owned town, no public stores here......
