Piston circlip and piston ring, 125cc

[Noobi06]

1. Today I installed the piston and it's circlips. The first one, I just slide in and push from the other sides with my finger, no big deal.
The second one, I can't push from the other side obviously since it is on the crank. After having a very rough time installing it, I got it in.
Both Circlips are sitting in their groves and are very snug, however I did notice that the open end (mouth or what to call it, gap?) is different on both circlips after installation. Even though both are in their groves as they should, one gap is bigger than the other. Is this normal or is it a problem? One is very tight and has a small gap, while one is bigger.
2. I measured the piston ring gap. (125cc, 54mm bore). 0.25mm feeler gauge went in easy, 0.3mm and 0.35mm also goes in but they are very very snug. However isnt 0.35mm too big? Im pretty sure it is supposed to be 0.21mm.
Note! Piston is a new 53.95mm wiesco. Piston ring aswell.
Cylinder is replated and is at 54.05mm, meaning it is 0.05mm larger than normal, also meaning that piston-cylinder clearance is 0.05mm bigger than normal.
This makes piston ring gap even larger.
We did this because according to the guy who replated, it is way better for road riding since the piston won't pinch as easily.
