Need help finding a case

[one1]

I might go ahead and grab the piston for $19

but I'm concerned over the cyl wall hone. Dunno.

Aren't I supposed to face the rings opening a certain way when I put the piston back in?

You will want to position the rings so the gaps don't line up with each other.

SO opposite of each other perhaps?

Also, the third thicker ring has openings on each side, any position relative to that?

It's left and right so maybe one main ring up and one down?

be sure to break the glaze on that cylinder or it will have low compression.

see post #18

get one of those and on a drill at low speed using lots of oil run it up and down in the cylinder for 15 seconds and it should be good to go.

Here's an excerpt from a GY6 service manual that shows a common ring placement....

Thank you, I guess I'll do it like this

Well this is as close as I can get to my bike. It's almost a dead match.

just not quite.

The rings are designed to rotate in use anyway to limit carbon build-up in the ring lands, so don't worry about it too much.

Here it begins............. first thing to show.

So the case is here and the hole for the shift tumbler is a little different. Looks like it will fit though so let's give it a shot!

I believe this ATV was an automatic based on what I am seeing.

Putting the engine in the bike now!!!!!!!! I bought some Lucas products to help with the piston wear and hopefully it'll run well enough to last through this summer then I'll decide if I wanna rebuild the top end or stick a totally different motor in it.
