I've searched and searched and I can't find any thread about ring gap for oversize rings. I would really appreciate the help.

I cannot think of one reason why ring gap should be any different based upon whether the pistons are a size over or not. I mean, the cylinder is a size over too, right?

Yes of course, I had them bored and honed to 3rd size over. I just wanted to make sure. I seconded guess myself a a lot.

Thanks

Hill,

Same ring gap as standard size rings! Got the key today, but realized the bike's down in Mom's garage, so it'll be a bit before I can try it. Thanks again!

p.s. remember to sand the key on both sides just a bit, u'll see what you need to do when you try to fit it as-is, for some odd reason its a little thicker than it should be.
