They are factory balanced.

 

I think his point is they are two separate part numbers, and not balanced together as an assembly. The confusion is why would the manual say you need to mark them, if they are individually balanced. I unfortunately don't know the answer, just trying to clarify.

 

Call Don he’s really good to talk to.
I would think there’s a mark to line up when you assemble it.

Primary’s have “x” on them to line them up for “balancing”. even the new style clutch doesn’t have a key on the spline to align the two halves so imo they’re not too worried about balancing. Secondary’s don’t have the “balancing” the primary does. New secondary clutch I wouldnt worry about it. Marking the used secondary I see being more important just because of all the parts wearing together. But isnt really an issue say when you’re installing a clutch kit because you’re putting new parts in. Just a better safe than maybe sorry theory on marking the secondary 🤷‍♂️

and how good are popo clutches really balanced anyway seeming the outstanding reputation for quality that popo has lol. And then you’ve got one clutch company saying it’s ok to dremel the inside of the primary to fit a spring that doesn’t really fit in it so how concerned are they about balancing?

 

Primary balance is important because it's directly on the crankshaft. Secondary can be close enough without balancing as 1 unit. Bolt them on, align them, run them.
