Off to the machine shop with my cylinder now. Does anyone know how far down to the bottom of the cylinder the piston rings travel when installed? There are a couple small scratches at the bottom end of this cylinder. Top most scratch is 1&3/8” high off the bottom. That should be fine right, the rings won’t ever travel that low?
I don't recall how far the piston goes but I don't think it goes past the bottom of the cylinder. That means the rings are at the top of the piston "X" amount.
Check with your machinist. If it doesn't work out for you, let me know for a return.

While I’m waiting for other parts to arrive in the mail, I’ve been looking at skids. I’m debating between the black poly skid for $100 @1/2” thick or the silver aluminum one for $80 @.125” thick.
Anyone want to weigh in? I like the black, but it looks bulky. The aluminum one weighs 7lbs.

I believe when I was looking at them I found poly in 1/2", 3/8" and 1/4" from different brands. If you will never ride areas with rocks the thinner one will work and save a some weight. If I was worried about rocks and protection get the 1/2" DRW. The extra weight of a skid plate is carried at the lowest point on the frame, I don't think you will notice it.

I have the GYTR and it does provide solid protection.

Thanks for the tip. Those wings on the side work alright with nerf bars? I’m leaning toward TM Designs poly skid just for the black color. They have the wings too and the guys said I may need to chop em off.

Cool, got any pictures?
I have only seen flat skid plates made from composite.
I prefer black too.

I have the gytr and had to notch the wings on both sides for the Tusk nerf bars. I like how the fasteners are recessed in it too. I saw some skidplates where they weren't and was worried the would get sheared off.

I have no issues with the Nerf bars and the skid conflicting.

Interesting alright thanks for the info. I can pull a stock photo but I will take some pics of the skid when I get it too.
It looks like the blue one is for a different model judging by the oil drain cutouts. Black one looks about right.

Got my new cylinder in yesterday, going to gap the rings today and see if I can get the piston installed after work.
Can anyone tell me what to gap the rings at for an 11:1 cp? I’ve read .020 on first and second ring, but not sure entirely. I know CP gave me a sheet with their specs but I want to see what you veterans have been doing reliably.

I try for .018 to .020 for the top ring and .022 to .024 for the second ring. You will be fine at .020 for each ring unless you have nitrous, turbo...
Too tight is bad, when ring gap goes to zero, you wipe out the cylinder and piston.

True. Thank you for confirmation.
