the balance shaft is in it for a reason, leave it in

Re: balance shalt
there was talk about this in the early 90's, I believe Stan Stephens done it a few times, but he later said that it isn't worth it as it can seriously affect reliability, but skimming the flywheel was also a common mod

Don't do it, you're better off getting a KX125 flywheel machined to fit and add a second pickup to do away with the wasted spark.

don't do it
when you hold the steering feels like 1000 volts passing through your hands

Re: balance shalt
Lightening the flywheel gives you better response / acceleration but at the cost of less torque.
Don't forget to check the balance after lightening
