According to the balancing guy, he is going to balance the crank, then the balancer, flywheel, and clutch assembly (pressure plate only; no discs).
So the rotating assembly will be balanced to itself...then balance the balancer and flywheel/clutch assembly. So the whole thing will be perfectly balanced...if you change out any components (balancer, flywheel, etc) then the system will be off balance, but not significant to cause any issues; it will still be light-years better balanced than a stock motor.
He said he doesn't balance balancers, flywheels, etc on circle track motors since they are always replacing parts in between races. But on a street motor which the parts will most likely stay the same for several thousands of miles, its preferred to balance the whole enchilada. He said you can replace clutch discs as those don't get balanced...but pressure plates, flywheels, and such are typically pretty consistent in weight.
Balancing is critical to motors that will see track time and sustained high RPMs.
So basically he does not want the crank to correct any imbalances due to the balancer and flywheel/clutch.
Does that make sense...?
I got worried too yesterday when I heard my stuff was getting balanced. They are checking rotational balance and front to back balance...from my understanding.
So far he commented that the Kellogg crank is very well balanced. He then added the Innovators West balancer and the whole thing stayed balanced. We'll see what happens when he add the flywheel. Should be balanced as all these parts should be well balanced individually.
I've been surprised because this whole build with the local engine builder, he has been building this thing like its a $100K race motor. I'm learning a lot... And here I thought we could just slap parts together. lol
