Help locating Honda Dream Rings

Thanks for checking the one you have.
When HONDA assembled the stock engine pistons there was not marking as to size on the top.
Replacement pistons will have a size (STD/.025 etc.) to show the actual size. ...........lm

Hmmm... I'm not the original poster, but I am looking at the top of my piston now and I see the arrow, but nothing to indicate the piston size. On one of the sides near the pin it says "C77" and on the other side it says "ART", but again, nothing to indicate the size. I measured the piston diameter at 59.95mm so I'm assuming that they are the STD pistons. Also, as for the original rings that were on the pistons, they had a "R" stamped in the top corner, the new ones have "STD", and measuring the ring gaps on the new rings when installed at various heights in the cylinders is within specs so I assume I bought the correct size?

Thanks for all the help. I cleaned the top of the piston and could not find any mark I could identify but it does say C77 on one side and ART on the other it measures 59.5 so I think it is stock. I Just ordered the ones off of ebay you guys recommended.

thanks again Adam

This is the type of marking you should look for. When measuring the piston, measure the diameter at the bottom of the skirt at 90 degrees to the wrist pin for best accuracy.

Just a heads up for anyone ordering rings from Ebay, I found one listing for .50 over rings listed under the part number that should have rings for both pistons, but the seller was selling rings for only one piston. Of course he didn't have a picture of the rings, only the box. I found out when I questioned him. I'm glad I did.

I got mine (along with pistons and such) from http://www.ohiocycle.com/

I was going to post another question, but seeing as how G-Man posted the picture of his piston (on the previous page), and this fits in with my question, I thought I'd ask it here.

I showed one of my pistons after I cleaned off all the carbon to a friend of mine that builds street rods and engines. The crown surface is about 75% pitted as if the carbon had eaten into it a bit, and he said that I should polish it up as much as I can (a mirror finish would be the best) because the smoother the finish is the less there is for the carbon to grab on to and accumulate. This makes sense to me, but so does UFO's and the Easter Bunny so what can I say. :-) I noticed the picture of G-Man's piston looks like it has a course finish on the whole surface which would the opposite of what my friend was telling me.

I spent the last 2 hours with a dremel tool and a buffing pad/compound attempting to buff out one of my pistons. It can be done but it is real slow going so I thought I should probably ask what the collective here thinks.

tnx
George

My reply.
Carbon on the top of a piston is part of life when ya run GAS.
How much is in ratio as to many things and with a street engine will be there no matter polished or stock.
Racing engines are a totally different issue.
When ya assemble your engine are ya going to take it totally apart and clean the pistons and inspect all the parts every 5 hours running time?
I sure don't and I don't polish the piston tops or INTAKES (some will love that) as it is what it is and to enjoy it I recommend ya KISS (KEEP IT STOCK XXXXXX) AND RIDE, RIDE, RIDE. .............lm
