Piston and crown or piston crown? Either way, just use a not too sharp knife and don't worry about any surface marks. They won't do any harm. Wire brush to finish. I'm assuming the piston is not still in the barrel?

Brillo pads??

I think it's called that... it's a green "sponge" that has soap in it that is used to clean pots and gives them shine at the same time!

Brillo Pads were accually wire wool pads with a pink soap impregnated in them.

A green nylon scouring pad (for pots & pans) is good for the final polish of the piston crown. A bit of copper pipe which has been flattened is good as it doesn't scratch the piston/head so much.

Just make sure the thing you are using has no sharp bits or burrs on it, or it'll gouge it

Membership - help keep us going!

Horizons Unlimited is not a big multi-national company, just two people who love motorcycle travel and have grown what started as a hobby in 1997 into a full time job (usually 8-10 hours per day and 7 days a week) and a labour of love. To keep it going and a roof over our heads, we run events all over the world with the help of volunteers; we sell inspirational and informative DVDs; we have a few selected advertisers; and we make a small amount from memberships.

You don't have to be a Member to come to an HU meeting, access the website, or ask questions on the HUBB. What you get for your membership contribution is our sincere gratitude, good karma and knowing that you're helping to keep the motorcycle travel dream alive. Contributing Members and Gold Members do get additional features on the HUBB. Here's a list of all the Member benefits on the HUBB.
