Add speed meter?

[meskola]

Hi!

I just got my first powerball, but now I regret that I didn't get one with the speed meter.
I found on the shop that you can buy one (for a reasonable amount of $$ ).

Now the trick is that I happened to buy a non-relabeled NSD Powerball which I understand is the same as the RPM powerball...

Can I still get a speed meter from RPM and "install" it by myself?
The place I bought the powerball from doesn't sell just the speed meter.

Greets!

Most Powerballs that can take a rev counter will be able to take the ones sold on this site. As long as it fits and the rotor has a magnet in it.

After searching some the forums here for a bit more it seems like I then have a Powerball which should be the same as the 250 Hz "regular".

Is there a way that I can find out wheter there is a magnet in the rotor?

Mine is in "Nano-second tech speak" a PB-188.

I wish I would've just bought a powerball from here with the rev counter in the beginning...

It should fit no problem. And it should have a magnet in it...
