According to my maint. page, I've checked the valves on my LIKE200iLX 9 times in 7 years.
"Felt" like one needed a slight adjustment 4 times.
I say "felt", because the variance is so slight with these thin blades.
If it is easy to get to your valves for a check - well, you know.
If it is a real chore to get in there - I'd give some thought to getting a different scooter. I'm never in favor of divorce ....but nothing causes me to fall out of love faster with a scooter - than one whose routine maintenance is an ongoing pain.😊
