I'm going to have my 1915 engine rebuilt, the bore is currently .040 over size now and will need to be bored out further to true the cylinders up. My question is should I have it bored and sleeved? I know when engines are bored too far it can cause over heating along with other problems. I thought is to incur the expense and have it done to last. I would appreciate everyone's thoughts. Thanks

A 60thou re-bore and a good radiator gives you no problems.

David, Frank has the right idea. If the block will not clean up at .060", then I would sleeve it. Have your re-builder trial bore it first, and he will be able to advise you from there.

Hope this helps.

You can clean it up and install sleeves but be sure they are cast iron and ask them if they can imbed them with a mastic that gives 100 percent wall to wall contact for good heat transfer.

It is not well known that a dry pressed sleeve only has about 75 percent actual contact and the heat transfer suffers.

David..FWIW my '15 engine was just rebuilt recently with 60 over and has a new flat tube radiator and runs like a top, cool as a cucumber. Moto meter never gets up to the "circle" unless it's over 90 outside and I run it hard, which I seldom do anyway. I like 28 mph!! :-)

Sleeve the engine when the pistons can swap cylinders. :-)
