Did it balance out O K. Or do you know.
Everything balanced well. I used a cnc for the pockets and made sure the setup was within a half thou on position. Magnets both weighed the same so only thing was maybe a little jb weld. I also noticed the billet flywheels don't get balanced because tolerance is so close.
The other thing to think about is with a single cylinder engine they are almost never balanced on the crankshaft side of things. I doubt a little glue will cause any more issues beyond design limits.
Also if anything it's smoother than before adding the extra mass to the flywheel. I think the weight smoothed out some vibration of the engine some.
