Cold mornings.

Does removing gas cap solve your dying problem? (That is my favorite thing to harp about!)

Unfortunately not, I avoid overfilling after reading up about it here these days hahaha.

Also, would like to update that after the valve clearance, the bike works perfectly now

I am not arguing! But please, someone! Explain how tight valves cause a problem in the morning but then runs fine all day.

I'm no mechanic Karl and if you don't know the answer then I hesitate to offer this thought, but; could it be to do with engine heat?  i.e. once up to temperature the valve metal expands to a slightly wider gap allowing it to run without dying?

Usually does not work that way. The long valve stems usually "grow" faster than everything else and close the gap even more. Given Honda elegant technology, it is probably reversed here!

D'accord with @CROSSBOLT,
valves are usually adjusted at "cold" (under 20°C) motor temperature, warm up after start and stop chattering by expanding. Then they fit smoothly and without gap onto your cams, valve-seats, etc.

I have heard that hard (morning) starts can be an indication of valves needing adjustment. Always assumed this meant the scooter would eventually start and run for the day. ....otherwise it would be a "won't start" situation, not a hard start.
Which part is getting warmer and or growing/tightening . ..is beyond my pay grade 😊

See, I knew I should’ve kept my thoughts to myself! 😂. Thanks for the insight Karl.

Yea, pretty interesting... no idea why. All the mechanics pointed towards the tappet being too tight, runs like a dream, it doesnt even need to be 'warmed' up now, I can just start the bike and move off just fine.

That is a good description of exactly how this model (and its relatives) and the Yager works. The Like 200i as well. Hot, cold and in between.

My Piaggio B V 350  came with a Cal. grade EVAP system. and something pluged and it cruched the gas tank down to a 8 Lt. from a 12.5 Lt. tank it is a plastic tank,.
