This is a single piston engine with 2 exhaust valves+++
I do not believe in any of "the exhaust valves which were sticking open" theory, as stated by Honda..if these were, most likely you would have them bent...
Would be eager to learn how they resolved this "sticky valves" issue, ask them please????
Ignition coil intermittent, yes , very possible...+++
Good luck with your CBR and have a trouble free trips.

The shop may have meant the valve clearances were set too tight and closed up when warm, leaving a valve or two open.

Yes, I omitted that detail in my first post. The valve clearances weren’t correct on the exhaust side. So they replaced shims and got them within tolerance.
