Modern Vespa

hello! I bought my Vespa lx125 3 years ago. the mileage was 17 thousand kilometers. now 34 thousand kilometers. for this 3 years valve were not adjusted.
is it worth doing this if the scooter works normally?

The interval is 6000km so you're well outside of that. Yeah I'd get it done.

встигну. я їзжу на скутері 12 місяців на рік
I ride on scooter 12 months in year.

Hello!
I adjusted the valves. The gaps were increased. I made 0.1 and 0.15.
The dynamics seemed to have not changed, it started to start without the accelerator handle and even the starter kick.
But there is a minus. The maximum speed was 110, it became 100 km/h.
