The argument that because the compensator fails it must be doing its job seems moot if they are already on like their 5th revision...

For at it's worth, I asked that question to the mechanic and he said no way, and he's never seen an issue in any they installed between two shops.

Funny thing is when the gearing ratio was lower in the primaries you never heard of a comp going bad, get your head around that........

NO from an engineering point of view-
absolutely NOT!
Should a crank come apart from the initial loading ...UNLESS it was constant abuse dropping the clutch at 60000 RPM maybe they woud have an excuse.
Maybe.
IF this is the case that HD needs a shock absorber in the crank drive train......I would say it is a rubber crankshaft and get rid of it.
The crank and flywheels are designed to absorb the shock, load and pwr pulses.
That is what they do as in any crankshft

No worries, as per usual all the exp here will come from those that have no exp with going to just a sprocket.
They will repeat the internet chatter and their fingers will just be poping the words.
From an engineering point of view with lots f numbers and stufffff.-
It comes dwn to two things
Power pulses, and low-speed absorptions.
(RPM divided two) broken dwn onto seconds if you want.
No matter what you do you have just two cylinders made to fire unevenly.
Almost end of subject.!
But for Now-
To get rid of the power stroke shock pulse Hd has used many types of comps.
Replacing them with just a sprocket has been a go-to for years and works well.
I know of no one that has broken anythng ever.
Shifting would be unchanged as the clutch is still the same and matching the dwn shift is all the same
.All that happened is now the engine is a little more direct tp the transmission.
Go for it and tell us how it goes.
I think you will like it a lot, and HD will miss out selling you a 600 dollar part again and again.

It does not matter-
There are single cylinder diesel in the world, two cylinders,
three cylinders that put out a hell of a lot more TQ then HD can dream of.
The number does not matter it is the power pulses.
Like I said, i know of no such crank failure in an HD, as screwed up as they are.
The twinks get out of phase from the get go.
Not sure what the M8 will do.
But again -if deleting the rubber biscuit on the crank and going to just a sprocket
destroys a crank-they did not have much of one to start with.

Probably the best thing a Twink owner can do is a crank weld job and call it done.
This will take care of most all the other problems.
It is a big wonder of wonders that HD does not have a "Stage kit " for this.

Even with the pressed process, its pretty damn rare to have crank problems, I think people spend a lot of money trying to prevent/fix problems that would never occur.
