Pro cycle is a parts supplier and not a machine shop. I think they should be sure to give the customer specs and instructions and provide support if there are questions but they can't be responsible for my learning errors. Hope the cylinder is good amd bikr runs great when complete!

It's not about it being someone else's fault. Sure, this is some pretty intense work inside the engine, so there should definitely be some reading up that needs to be done before attempting this kind of project, but just something that says "the piston rings need to be gapped before installing" would at least let people know that it needs to be done.
Having never done any work inside the working parts of an engine, I'd never have known that it needed to be done, same as the OP. Still, PC and the OP are working on making everything right, and I'm sure this will turn out fine in the end. It's been an educational thread to say the least.

sorry, but this ain't really a specialized incident.... any piston rings inside of any engine need to be gapped... there's this thing that happens when metal gets heated, called expansion..... jr. high science class..... and in different applications/alloys, the gap is different.... you can't argue w/physics.....

agreed 100%. but it is extremely possible - likely even - that someone inexperienced w/this type of endeavour, would not know that the rings they yust bought - w/matching cylinder and piston - would not be plug-n-play...

I can't believe my quart of oil doesn't say, " torque the drain plug before pouring into the engine."

Just for the DIY crowd

Ok all you he men. What is the gap for these rings? I wouldn't think you would find in your Suzuki manual. If the specs are provided, then maybe you got an argument. If not you are just argumentative.

Maybe you and a machinist might know the thermal expansion differences between a forged aluminum vs cast pistons vs steel or nikasil covered aluminum cylinders but not everyone does.

My situation was a little different. I got a forged piston and took it to a machinist to bore the cylinder. The piston came with cylinder/piston clearances along with end gap recommendations. His recommendations was pretty spot on. But one way or the other, you kind of need that.

I am not saying anyone is at fault. The OP spent $2,000 and got what sounds like a plug and play installation. The cylinder has been machined to fit the piston. I don't blame the OP for assuming the rings also fit. If procycle provided ring gaps, then that should be a heads up. I am just saying it cost Procycle a hell of lot less to point that out, then some customer spending the money and not doing it.

Everybody who has done a big bore, raise your hand.

That's why I mentioned the ring gap on pg. 5. post #65.

If I buy a sparkplug from Procycle for my DR is it also his responsibility to gap it for me or include a note that says to check the gap?

Thanks Jeff for all you've done for so many here and for your continued help for this guy. You are a class act in my book.

ya, i am sure yust as many folks have installed new pistons/rings/cylinders as have installed new spark plugs.

btw, i also think procycle jeff is a class act. which is why i bet he now goes out of his way to offer ring gap services and more deliberately point out the necessity of doing this in the future, for those who don't want to have it done for them.

I'm a believer, that all bores are not created equal. The measured gap, in the rings is there to allow the ring to compress as it slides up and down, along the bore surface which could have slight irregularites.
I never expect the rings to be perfectly gaped from the manufacturer.

You're probably right.

But checking ring gap is as day one basic as checking plug gap. (No offense intended to the OP, I've made my share of mistakes and expensive educational experiences) So the guy who directed the "lame" comment toward Jeff is way out of line.
