APE Ultra Crank assemblies, complete with Carrillo rods, ready to ship out. Two CB750 and one CB400F

How much? Might need to start considering one for the road racer. Could you cut the end of the crank off for the charging system?

That's just beautiful...

The 750's are $1395.00. The CB400F is more because the rods are custom order. We can cut the end off.

It improved my CB750 more than I thought, APE stamped crank with Carillo rods. Very stable idle and quick throttle response. The CB750 SOHC should have had it from the very beginning. I see it as a corrective action.

I use a new cam (DP315) that surprised me to have such low and stable idle. I'm sure that the APE crank had a lot to do with it.

From the Aussi master of performance cranks, Bill White.
A little heavier than your's Brent, because of the sidecar application.

G'day Keith,

They are indeed Falicons.

I haven't forgotten your gears mate.
The motor is on the bench, but I'm struggling to find the time/motivation to get out there and crack it open.

Cheers,
Brian

Been busier than a one armed paper hanger.
Will reply to your email over the weekend.

I'll bet you could pound a piston to bits without breaking that rod! I could see that rod cutting a circular swath through the lower case, clutch basket, cylinder block, and the cylinders if it ever parted ways with its piston...

Well, maybe it would break, but it would not go quietly!

Captain · « **Reply #20 on:** November 18, 2016, 08:43:34 PM »

My current engine has a stroke of 69mm and a current red line of 12000 RPM and this translates to a piston speed of 27.6m/sec (piston assembly weight of 185g). In order to handle this and have further RPM capability the design brief was for Titanium Rod that was stronger than a steel Carrillo and rated to 13000 RPM (30m/sec).

This picture shows both a Carrillo and my Titanium rod side by side for comparison purposes. (The Carrillo is the smaller)

You won't break one of these!!!!

Bill/BentON Racing · « **Reply #21 on:** November 18, 2016, 10:28:19 PM »

I didn't think I'd break a Carrillo .....first time for everything I guess, yes they become little saws!

mick7504 · « **Reply #22 on:** November 18, 2016, 10:58:51 PM »

You don't mess around Bill.
That is one Carrillo that can be called the sacrificial lamb mate.

teebee67 · « **Reply #23 on:** November 19, 2016, 12:35:09 AM »

Did you make or have the titanium rods made or are they available generally, if so from where please?

MRieck · « **Reply #24 on:** November 19, 2016, 06:03:59 AM »

Crower will make them. They have the specs for 750 rods. I have always felt a Carrillo "A" beam rod would be a great piece for the CB750. It is lighter than the "H" beam (which is fairly light) and plenty strong enough. I run the A beam in my FJ
