RE: Why not make Dyna motors counterbalanced ?
My '07 Heritage doesn't vibrate at 70 in 6th gear. But then, I can't find any speed where it vibrates. I do kinda miss the idle shake of my old Low Rider though.

Man philm you have not looked at any of the spec sheet on the B motors, Harley says they both have 85 ft Lbs @ 3000 rpm. Doesn't list HP. I would bet the B motors are with in a pound of each other. I would bet a cold pitcher of your choice you could not tell the difference in performance. I here all the time about the mystery foot vibes at 70 so I figure you have to be 70 yrs old to feel them. I would also say there are a lot of B motors out there that would run with you all day if you want. My bis *** needs to strech with the gage hits E. So what your saying is the balanced motor that takes out 90% of the vibration at some mystery speed puts it all back in that is imposible. So if the B motor is vibtating at 70 so is the non-B motor at 70. I have ran my B motor all speeds up to 85 above that and I'm not comfy. that would be a hell of a ticket in my state. I wish they were options on all models. My .02 worth love the B motors. Tom

Guess I should add this to my cliche'... Different seats, different pipes, different bikes, and now different motors for different folks.... No biggie.
It was not my intent to say that there are no HOT way-fast b-motor bikes. I know way better than that.
What I do know, is that I have owned three (3) TC88's and one 88b (2002 FLSTCI). The harmonic that resonates through the grips & floorboards is just not my cup-o-tea. If it is yours.... that's great.... enjoy it!
As far as "how much" power is consumed by running the balancer assembly, I do not know (or care)....
I'll "match that pitcher" by identifying a b-motor 10 times out of 10 by riding them ~ even w/blinders on....

btw - I was also "not" trying to slam the B-Motor bikes.... god knows I get enough of that for riding the "sharknose"!

Why they made a TC88B is beyond me other than they fit the engine to that specific frame versus adding external dampers.

That is probably true.....
But you don't really see the mounts anyway........

I read that somewhere that the main reason for the going counterbalanced in the Softails was aesthetics,the way the motor sits in the frame without the rubber motor mounts.

the second part of the story: as we all know...softails ARE mounted directly...so before switch to TC...harley was getting a lot of complaints of the riders because of the excessive vibration on the Evo engines.
Several attempts to reduce the excessive vibration were made...in 1995 the softail models got the so-called "bonneville gear ratios" which were taller than any other family...lowering the RPM's and by that the vibration - but that didn't solve the problem
many softail riders were trading their bikes mainly into tourings because it was almost impossible to make a decent travel without making several stops because of the annoying vibration....which usually got worse at highway speeds.
so, when the time to redesign the softail family came, there was a great challenge...what to do to quelate the vibration...they had two options one of that was going into rubber mounting the engine...but that approach wouldn't fit in the softail "character"...then the idea of the balancers came up.
That's why the dyna and the touring came with the TC in 1999 and softails didn't...they were working out a way to put the engine in the frame without messing with the softail look.

Perhaps a dumb question ( I have a lot to learn ) but why not run a counterbalanced motor in Dynas ?

I know people like their Softails and that's cool. There's a few that blow my skirt up too. I just really don't like the "B" motor. It's too smooth at idle and if you can't feel that buzz, you ain't revving it high enough.
So what your saying is the balanced motor that takes out 90% of the vibration at some mystery speed puts it all back in that is imposible. So if the B motor is vibrating at 70 so is the non-B motor at 70.
