Falicon and Darkhorse Crankworks

[crowgo]

As before, this is an '02 FLHTCI with a 95 BB kit.  I'm going to have it rebuilt. Does anyone know anything about Darkhorse Crankworks in Osman, WI or Falicon Crankshaft Components in Clearwater, FL?  Tjanks.

I had a crank done by Falicon.  They do good work but they could provide more complete advice.  Darkhorse is top shelf but their prices are out of site.  I ended up going with Revolution Performance for my most recent flywheel work.

I did Darkhorse.  I requested a tighter tolerance in Balance, Runout, Preload, and got an amazing lower end.

No matter who does the crank work, do you need to send your crank, cases, pistons and pins or just your crank w/ pistons and pins?

Since your '02 already has timkens, call and ask the people you want to do the work.  They might get by with just the crank, if you can do a really good job of measuring the piston weights.

Had Darkhorse plug, weld, balance w/H-beam rods this last winter. Worth every cent...smoooooth.

[AllanW]

Deye76 is right, I did the same thing.... Smooooth

smooth.............but over priced I`m buying my first  R&R crank this week...........anybody have experience with this new crank

thank`s larry

the 5pc ?
I like the idea 

[ThumperDeuce]

I sent R&R an email about a week ago asking when their new wheel set will be available for the "B" engines.  So far no responce.  Anyone know when they will be available?

What I spent at Hoban Bros., bout the same as the R&R. R&R wasn't out yet, and Reggie wouldn't give a firm date.
I also like the idea of a 5 piece.

I just had a 4 3/8 stroker built by Darkhorse. They installed the Timken on the left side and bored the cases for the 4 1/8 Axtell cylinders. I should received it in a few days. Hoban Bros. are very informative and a pleasue to work with. Once the 117" is complete I'll give a complete rundown. I received the Axtell 4 1/8 cylinders last week and they are truly a work of art. Don at Dewey's heads did my heads and they are equally as nice. Don was also great to work with.
I just need some time. Gotta go out of town this week for work but should hopefully get on it next week.

 How do we get in contact with the company that is making the five piece cranks for Twin-Cams?

The 5 piece crank has been around for years and years somewhere along the line 1999 actually the big 4........ HD HDSE S&S Jims
must have  got to gather and all made and have to take  credit for making the worst designed crank in the history for the Harley Davidson



Thank`s guy`s

[TXChop]

R+R uses a different rod length. Not a big deal if doing a build from scratch though...I am sure they are a very nice units.

I have experiance with Darkhorse on 3 cranks, and all 3 have been spot on.

[Hillside Motorcycle]

Believing that those require a piston, as well as case machining.
We use Hoban Bros., as our go-to crank source.

yup..... and then the with the TC the MOCO had to get cheap on us

Truth be told,

The straight press pin came from XR750 Factory dirt track motors back in the late 80's as the factory found the larger pin and bearing design added longevity to high compression / high RPM motors.  Those 750s put out a lot of power, still do and the longevity of the larger pin is a fact.

1.250" pins are a piece of history, the factory has gone to 1.500" on Sportsters and air cooled Buells and the longevity we have found through endurance racing the new flywheel assemblies over the 1.250" pin stuff is amazing.  We raced a lot of the new stuff well before it hit any showroom.  That goes back to the original press pins in 1999.  There are some tricks that you need know when working with press together flywheels & pins, but it is my belief that we have a firm grasp on their shortcomings, with some attention and assembled properly they will outlive a 1.250" pin and bearing by far.

There are so many people pushing these larger motors now, the numbers for a lot of these street bikes has far exceeded any proportional numbers for nutted/tapered shafts.  There is no comparison, and as we push you will always find the weak link. 

The amount of flex a flywheel assembly will go through at high RPMs is astonishing, the straight press pin (with a Pro-plug) is key to keeping this flex to a minimum. 

There are other factors that the factory has engineered out of the process that has allowed some failures back in.  Manufacturing process's mandated this to a certain degree, but in street trim they are fewer than most here may believe, but nobody leaves their bike in street trim, do they?

Money wise, only history proves wether something is over priced or not.

We (H-D dealership) use Darkhorse for our high performance builds and I used them on my own bike. Top notch tech support from John and e-mails always answered. In my opinion worth every dollar for the piece of mind of knowing it is done right.

so what is your professional opinion for the limit on hp/tq on stock cranks?  thanks jeff

[John D]

Jeff,

That is what I call a loaded question.  There is no majic number or threshold for these cranks.  To a certain degree it comes down to,

(A) how straight and true it started out at
(B) how it is treated while in service
(C) state of tune
(D) primary and secondary drive system
(E) and yes, amount of torque

I have seen stock cranks in stock bikes have excessive run-out and I have seen stock crankshafts in some pretty stout motors stay straight and true. 

The biggest thing is measurements.  Know what you are working with, document it and check it when you can if it is untreated.  If you are not going to treat the bike with respect you will want to look at Pro-plugging it at a minimum.
