Flywheel - to balance or not to balance? This is the question

Post by Micha »

I know that during the motorcycle production, this wheel was balanced.
The question is, today, after about 70 years, should I invest time and money and find someone who knows how to test and true it?
Or is it an unnecessary action?
Have any of you ever done this before?

Based no my experience with an R75/5 where we balanced the piston and rod assemblies with each other as well as the fly wheel I can tell you that it does make a noticable difference in smooth running. However, that work is easier on a /5 than it is on a /2, and considering the sedate around town use the bike gets these days, I don't think I'd bother again. My R60/2 has new 1st over pistons with no special attention to balance and runs just fine. Unless you're doing something exotic like building a vintage racer or something, or if there is an obvious problem, I think flywheel work is overkill.

There is no need to balance

They are done at the factory and unless something happens to take metal off the flywheel I would say no. I have not balanced any of mine.
