So just to be clear @Mastermind , we have to use the wrist pin bearing included with the kit?

In all classes.

The wrist pin bearing can be from any manufacturer.

In all but class three.

The wrist pin must be an aftermarket part.....and should be original to the top end kit that is used.

Kevin did you use the bearing in the box?

Yep. But only because that's all I had. It's getting replaced with oem when it comes back apart for porting. I don't see where changing out a known source of catastrophic failure, yet doesn't add to performance, should be a big deal.

Exactly.

The pin weight can be performance enhancing, and won't cause failure.

That is why I wanted to see it retained. The bearing won't change performance, but can cause failure......so.....

My white box (farmertek?) cylinder has minimal squish without the gasket, also a bit of 'reverse squish', .017" by the cylinder wall and .013" in towards the combustion chamber.

If someone were to fix/flatten the defect/hump on the squish band would that disqualify it for class 1?

The complications begin, lol...

Mostly I would say no disqualification unless you spank everyone easily. But the original idea of class 1 was as close the out of the box as most people would get. Now maybe if you prove that you flattened it without a lathe or mandrel/cutter, something like sticky sandpaper on the piston.
I know I'm going to be honest and I'll assume everyone else is too, it seems more fun that way. Realistically we all are going to end up doing some defect cleanup here and there, after all we do want them to stay running.
