Cams are rarely balanced. Lobe itself is a large imbalance. No one really tries as spring pressure makes it near impossible. Of course a five pounder may be a bit sticky but within reason should have next to no effect. Newer Iron.

I've been looking at the cam shaft for a trigger location. I've
been concerned about the shaft getting out of balance by attaching a
magnet to it. That is why this "NEW" Hall effect device caught my
attention. If I can keep the magnet small, I can mount the magnet
on the cam chain sprocket. That would give me some flexability in
the trigger timing.
The bike is a 2000 Kawasaki KLX 300 dirt bike.
