The " B " engine is internally balanced versus the " A " engine that's rubber mounted in the frame .

The "B" engine is an aberration of nature,

a Harley engine that does not shake. Not for me thanks.

I meant, and shoulda said ".. a traditional Harley that doesn't shake .."

The V-Rod is not supposed to shake, the LowRider is supposed to shake, IMHO.

.. don't I recall you saying if you ever had your cases apart again,

you'd probably do away with the balancers?

Yeah, but not due to the shake.... I'd debate on doing away with the balancers for the increased redline (currently 6200, increase to 7000 rpm).

Then I'd have to ask myself is 800 rpm really worth it???

Huh. I didn't know they raised the RPM above 6200,

just never thought of it. And with the long stroke, too.

Does it take lighter pistons and/or rods?

The moco didn't raise the RPM.... my motor was built to withstand a 7000 RPM redline, but I don't feel confident the counterbalancers would withstand constant rpms much above 6200.

No I didn't really mean the MoCo, like it was a change in the spec,

I just meant I didn't know higher rev was part of a higher state of tune.

I was surprised before that just opening up exhaust and intake flow

got a flash with rev limit changed from 5500 to 6200

so I guess it shouldn't be too surprising that it can be raised further.
