Keys sticking on the repetition lever

So, I'm updating you on the situation.

Yesterday I called a very competent technician and he basically realized that the problem with the repetition and the fact that I couldn't play piano (pianissimo) was due to a completely misaligned regulation.

In practice, there was an escapement of about 10mm, which is far too exaggerated compared to Yamaha standard parameters.

Another thing he noticed was that the springs were very strong.

He then proceeded to perform a new regulation starting from the base (realigning something I don't remember), also adjusting the correct hammer height and their drop.

He also applied some powder to the rollers that were making a bit of noise.

In this way, he managed to reach an escapement of 2mm, which is the Yamaha standard.

He advised me to try it like this, without adjusting the springs for the moment (which according to him are too strong but should be fine anyway) and without touching the key dip.

Regarding this latter aspect, he told me that on the highs and lows the dip is okay, while on the mids there is a bit of resistance, so if desired, it could be fixed.

At this point, my evaluation.

Now the repetitions work much better, it's possible to play piano, and the timbre has definitely improved.

So, the regulation performed by the technician has certainly brought the piano back to the parameters that the manufacturer intends.

However, I am a bit worried about one thing: with this new regulation, I find it harder to press the keys and I notice more heaviness.

In the past, I have had problems with tendonitis in my right hand, and yesterday after trying the new regulation for only 20 minutes, the pain returned to my hand.

Since the technician has to return for the tuning, what can I ask him to lighten the keys?

Can adjusting the dip resolve it slightly?

It could also just be a matter of habit, but the thing scared me a little.

Thank you for your suggestions.

The escapement at about 10mm..........!! meaning 1 cm..did I read that correctly?

Yes, you read that correctly.

It seems excessive to me, even if I am mistaken. I don't want to always play devil's advocate, but in my experience, specifically setting wide let-offs on a piano with a heavy keyboard or a hard mechanism with problems can be a trick to make it appear easier to someone testing it superficially for purchase....they are "trade tricks."

Anyway, by redoing all the checks from scratch, everything can be remedied; modifying only one or two regulation parameters to achieve an apparent balance between measurements could instead be a remedy that is not convenient in the long run....

This "trick" was surely used.

Now I am asking you for advice.

With this new regulation, which is the correct one, what should I ask the technician to lighten it even just a little bit?

Thanks for the support.

It depends on what makes you feel the weight, friction? Excess lead? Hammer action issues? I wouldn't know from here; the technician should have already understood where the problem lies if they inspected the piano
