Ypvs servo motor
-
The way the guy in the video has done it would make the valve not operate correctly.
The pulley on the motor is not the same size as the plastic pulley on the cylinder.... It's changed the rotary parameter and timing.
Also I'm pretty sure it would be running backwards as the servo is now facing the cylinder.

Yeah that would make sense, might be fixable with a zeeltronic though? -
It may be possible with the zeel.
If it's running backwards then you'd need to invert the pulleys.
Then use the zeel to alter when it opens and closes, if necessary don't make it 100% open. It may still feel "off" and not give that YPVS feel.

I was told, time spent fine tuning powervalve timings is worth its weight in gold.
In my opinion, this all depends on the usage.
For road racing, a finely tuned opening wouldn't net huge gains. Since once you are fully opened, you are likely to stay that way. I.E. does the Honda RS125 even have a powervalve? Or is it just chocked wide open.
MX a working powervalve is important, but there is always the gear below? I know people faff around with springs to get that powervalve open earlier/later but often it's just about shifting the timing.
I was told by a local technician at Yamaha that tuning the valves timing will net you decent gains. I was always too lazy to actually do any of this.
