I bought a new toy to play with -- a cylinder leak down tester. I tried it out for the first time on what I call T-2, my 214cc TW with the 70mm oversize Wiseco piston I honed the cylinder oversize on and I also hand lapped the valves, aka a cheap valve job, though I did install new valve stem seals.
I have never done a leak down test before so I don't know if the engine is supposed to be hot or cold but this engine was stone cold. Basically I just watched a YouTube video.
Overall I am pleased. The combustion chamber seems to be well sealed according to the gauge. So if someone says you can't enlarge a cylinder with a hone I say they are full of sh*t. It can be done and done with very good results.
