You do not need to remove one. 99.9% chance is one is positive, and the other is negative. They put both of them in to balance the weight out. Basically just put your sensor up to it, and it should pick one of them up.

If they give you a problem (they will with certain governors), then heat one up with a soldering iron and it will fall out. You can fill the hole with epoxy or jbweld to balance it back out.

I could just be a counterweight, too. If they're both magnets, the CSM RL, for example, will pick it up as doing twice the RPM it's actually doing. Suck it and see, I suppose!

what he said ^^^

If you have a RL or similar, it will read both magnets. In that case you have to remove one of the magnets and replace with a counterweight of fill it with JB weld.

If you're using a revmax, GV-1, Multigov pro, Tj pro, etc then they will only read one magnet and you can leave it.

I would however test if the magnets are facing opposite ways ie one is north and the other is south. Its pretty easy to do. Just get a magnet and put it with one face over the ones you have install. One should attract it, the other one should repel it.

it definitely there for counter weight

The CSM will read both magnets regardless of their polarity (upside down or vice versa). The ATG will only read the magnet set one way.

You shouldn't remove the magnet, just programme your desired head speed in divided by 2 ...

You'd need to program the headspeed MULTIPLIED by two, and given the best you'll get out of the RL20 is 20,750 rpm, you'd only be getting 10,375 ACTUAL rpm (since the magnet is passing the sensor twice every rotation instead of the once the gov is expecting), giving you a touch under 1200 RPM at the head! So since it's a Revlock, you'll have to get rid of that second magnet. If you're concerned about balance (I don't use a counterweight and mine's smooth as)you can get a non-magnetic counter weight instead. The soldering iron usually works if it's been CA'd in, although they can be tough to get out. It'll kill the magnet, too. Maybe that might be the answer- heat it 'til it loses its magnetism, then its just a counterweight. Never tried it, don't know if it works...
