MOPED ARMY

Muriatic Acid dude

you can also use naval jelly/phosphoric acid. and having siezed a bike shouldn't increase your likelyhood you'll sieze again. in my experience mopeds are very forgiving.

also, i know this sounds like crazy bandit talk but you should try to salvage your old polini piston and rings. i've taken hard siezed (rings stuck in the grooves-piston scored as fuck) kits and completely saved them, got them running with good compression. sand the fuck out of the rings (as long as they are not snapped) and the piston and run it. i know it sounds like a terrible idea but i've seen it work well. its free try it. or if you really don't want to do that sell me your fucked rings and piston!

thats fine. new rings.

before the ehaust port up near the head is what makes cylinders suck.

god i wish my kit wasent so badly fucked.

why dont you just run a hone through it briefly

or go to a local machine shop & have them look at it

I think the better you can repair it now the longer overall it will last

I have re used mildly dammaged pistons & had no problems as long as OD of the piston that rides in the cylinder is good

I actually took the side of the piston to the side of my 14 inch cutoff wheel while rotating the piston to re polish (sorta) the sides of it, came out great

take care

Its been my experience that once siezed they are goosed, you can get them running again but its just a matter of time before they sieze again, honing is a definate no-no.. the nickasil is only microns thick and once gone youre down to aluminium.

So thats what that sound is....hahaha

my polini seized hard and i saved it, I also made the exhaust port like a skate ramp and ported the fuck out of my cylinder so i don't necessarily believe u can "chip" the nickasil to an adverse effect.

most reliable cylinder ever after that, and runs cold.

Elliot, do you have a picture of you exaust port?
