What can cause an inlet valve to get stuck?
The whole area was well oiled. The push road is delivering plenty of oil too.
Took it back to the workshop that overhauled this engine 2 years ago (I supplied them back then with new valves, guides, springs etc, quality stuff made by www.intervalves-technologies.com).
I had 1 guide spare and they used it now and managed to fix the head.
They also confirmed that it was not a poor oil supply. On the other hand, they couldn't say what caused this malfunction and that's actually what interests me the most here in this whole story.
I had a hypothesis that maybe they didn't make a precise enough machining at the time, and that the bore for the valve stem was too tight (which they don't want to admit).

Since that overhaul ca. 2 years ago, the bike did only 100-150 miles.

Or the valve stem was not straight.
