Ypvs servo motor

Hey yeah, my first instinct was to go on ebay and aliexpress, then i remembered that sweden has fees from taking packages outside of europe, so every 1 quid dc motor would end up around 10 quid each because of customs etc, and not to mention the fact that it takes a long time for them to arrive
I dont know how dc motors work, i would think that the most important part is the torque it produces, but im not too sure
But thanks for letting me know that its called a 835 dc motor specifically, easier to find what im searching for now@Arild Isn't Sweden an EU-country? I live in Norway and there are virtually no extra fees ordering from China or other countries, at least when ordering stuff worth less than 300NOK (about £25). And Norway isn't even EU. That's strange.
But you could try to search for hobby stores in Sweden at the web. Some stores might have a 385 motor. As I mentioned, it's an ordinary hobby motor.

I’m sure you’re thinking of it stationary, when power isn’t really an issue. When you’re in most gears and accelerating it moves fast enough. I understand where you’re thinking is coming from though... -

Idk why sweden has done it they way they have but basically postnord, which takes care of the packages as soon as they enter sweden, take 70kr just to handle the package, and then they also take 10% of what the package was worth and add it onto the 70kr, so even the smallest things end up expensive, except if u order from wish, since wish takes care of the fees but shipping from wish is always around 70kr anyway, so there is no real good way of buyinf chinese things into sweden anymore -
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.

My servo do t seem to be getting any power it's not doing a cycle all the wires look good connections has me stopped myn is a 4 wore plug witha separate yellow wire it has me stupped
