I remember when that guy in France bought his unit, and I have watched his learning curve. I comment on many of the small Chinese mini-X vids on Utube when they come out.
Anyway, he did a good summary. But....and I have beat this horse hard...many of the issues/fixes with these machines have been documented here, and are easy to find, with pix. Comments on Utube are chronological and do not allow posting pix. They get lost. Case in point: zerk fiitting features and modifications. Tough to have to figure these all out for yourself when they have been documented on TBN. Specific Utube vids would be more helpful to the new owner. e.g. "Adding an oil cooler to my 1T Chinese mini-X", or "how to add wheel brakes to my 1T Chinese mini-X", etc.
I have operated one of the Chinese 1T minis with the 3-cyl Kubota diesel engine. It is a bit less jerky, but that is cuz it runs at lower RPM. It uses that same valve and pump as do the 1-cyl gas or diesel units. Shock-RVs in key circuits would perhaps improve that feature even more.
