Is there a gap where the rings are in intake side more than exhaust side

It’s hard to see but the gap between the piston and the cylinder is quite a bit bigger on the intake side this is where the ring stopper things idk what you call them. Anyway I’m wondering if the rings aren’t quite right or if this is normal?

Cylinder to piston clearance looks excessive, did you measure the bore before buying the piston?

No I have zero stuff to measure it I think it’s just loose cause it’s a wisco piston

Wisco's 801M06640 piston is 66.36mm diameter which gives a cylinder to piston clearance of 0.040mm, which is less than the OEM spec of 0.060-0.075mm...

You should measure the bore...
