So I have have a 92 Suzuki LT80 just put in a new Piston and Cylinder only getting 60psi compression. Maybe i got the rings messed up. One is marked D and DY and went to https://www.miniriders.com/threads/ring-position.20906/ to set them in place also put Cometic gaskets on it just wondering if that cooper head gasket being so thick could be the issue of if anyone has some words of advice. Getting spark and cant really tell if im getting fuel or not. any tests i havnt thought of would be appreciated

 

That's for a 4 stroke motor.
If the rings are marked, the mark goes up. If it went together smoothly you prolly have them correct. It's hard to get the cylinder on the piston if they are not correct.
You aligned the ring gaps with the pins in the piston???

 

I will double check again today. It ran when i caught it on fire and replaced on the electrical stuff and plastics. So changing the Piston and Jug was just bonus stuff but i put the old jug on and piston and still only 60psi. I have sprayed either in the carb and jub still no fire same with gas. Best thing i get it puffs of smoke and a big poof once in awhile out the exhaust
