MetraKit 65cc Soft Seize Issue?

I have a:

MK65 - Tecno Boss - 16.16 SHA 80 Jet

While breaking in the kit I was riding pretty easy going down a light gradient and I had a soft seize, so I waited a bit for the piston to cool down, checked to see if it turned over easy and turned around and headed home.

When I got home I checked the cylinder and there seems to be a small smear I can feel with my finger on the cylinder wall, it seemed minor so I put the whole thing back together.

I believe I soft seized because of an air leak on the intake manifold, so I am moving up to PHBG spigot mount.

I took the bike for a ride and I seem to have lost no power. What should I do, eliminate the air leaks and ride, though take it easy for while couple hundred miles?

Or should I hone the cylinder. It seems to run fine though? Thanks for helping me out I am a bit new.

The rings are fine, not stuck or anything.

Just rock it. couldn't hurt to use some two stroke oil and 2000 grit and try to clean up the bore and piston though...

Try a thicker oil mix. I seized my metra early on running 50:1 klotz, not even being hard on it. So I switched to 37:1, ran like a champ even through some pretty intense abuse. Went back to 50:1 eventually, and it soft seized. Again, I wasn't even riding hard. This thing is awesome, still runs pretty well even after all that and _another_ seize. This time it was just me being an idiot though.

get a bottle of muriatic acid from the hardware store.

dip a q-tip in it and use it to get the smeared aluminum off

the cylinder wall.

be careful, this stuff is nasty
