Words of Wisdom from a Honda Wrench

In 1970, Italian born Eraldo (Harold) Ferracci went to work for Chiaccio Motors in Riverside, New Jersey.  During the normal 9:00 to 5:00 work week, he works as their shop foreman.  But come the weekends, and he can be found at one of the National Drag Racing Events from California (Freement or Irwindale) to Kentucky (Bowling Green) to Florida (Tampa or Orlando).  Eraldo started drag racing Hondas in 1970 with a slightly modified CB 750.  From that time on, he's been running in the modified classes and more recently, in the "B" Gas class 1162 cc.  In 1975, when the smoke finally cleared, he came out number 5 in Overall National Competition with his fastest time posted in Florida at 9. 36 E.T., 146 MPH.  The racing world is nothing new to Eraldo.  In Italy at  age 11, he worked part time for then World Champion 500 Gilera rider, Libero Liberati.  At age 18, he went to work for Benelli R & D and was part of their factory road racing team from 1962 to 1966.  Space prevents us from listing all of his activities for the "competition".  But from 1963 to 1964, he was National Champion in 125 cc Class.  Benelli brought him to the U.S. to assist with their mini-bike marketing program and, in 1967, to assist their road racer Bertorelli.  Later, he worked with others to organize Benelli's training center and service department.  But his racing activities continued including flat track, TT as well as road racing.  Riders he has worked with include Gary Nixon, Dick Mann, Ronnie Rall, Eddie Wurth and Elliot Schultz.

Besides his current racing activities, Eraldo is involved with Ravesi, Norris, R.C. Engineering, Venolia and MPC in developing different types of mostly top end related parts.  He does all of his cylinder head work himself.

Eraldo offers us some words of wisdom for the serious engine builder.  He tells us that anytime you are installing a crank on a CB750, be it a new part or one you're going to re-use, you must measure each main and rod pin for out-of-round or taper with an outside micrometer.  After that's done, lay the crank alone without rods in the cases with the bearings that are called for from the chart.  Lay in your pieces of plastigage; put on the lower case half; and torque to 16 ft. lbs.  Eraldo does this plastigage check four different places around each main and rod journal.

After cleaning all traces of plastigage, again lay in the bare crank.  Don't get any oil between bearing shell and cases.  Put on bottom case half, torque all the main bolts up to 10 ft. lbs. and hand spin the crank, making sure of its free rotation.  Torque all bolts another 2.0 ft. lbs. and again check for free rotation.  Eraldo keeps torquing in 2 ft. lb. increments until he reaches 16 ft. lbs.  If you can find one particular bolt that's keeping the crank from spinning, note on the case the level it can be torqued to without stopping the crank's movement.  On final engine assembly torque it to this figure.  As long as it's above the 12.0 ft. lb. level the bolt will stay and not cause any problems.  Measure, checking and rechecking is essential if you expect the engine to perform reliably, especially under the extreme conditions of racing.  "Above all" according to Eraldo (Perhaps paraphrasing an old Italian (?) saying), "cleanliness in engine work is next to Godliness".

Cycle X Lightened Alternator Package

Quote: "Those Honda CB750s are really smooth running."
Quote: "I installed an RC engineering lightened rotor for more rev capability (love that old performance stuff)"

Well, the second photo shows an early (6.9 lbs), late (5.7 lbs) and a Cycle X alternator (4.66 lbs)

Before we go any further!

Our balancer shows stock Honda CB750 crankshafts and alternator rotors out of balance. This may be due to mass production or just 70's technology.

So, lets say your crankshaft is out of balance 6 grams (we have seen this). Let's say your rotor is out of balance 5 grams (we have seen that also)
Lets say you reassemble your motor with heavy side of the crankshaft and heavy side of the rotor on the same side. (Do the math) Smooth running and happy?

The third photo shows an old RC lightened rotor that is out of balance 6.846 grams (More math)

Introducing the Cycle X Lightened Alternator package:
- Lightened and balanced to perfection rotor.
- Puller to remove you old, heavy and out of balance rotor
- Oil seal for your starter ring gear.
- Cycle X exclusive no leak gasket (No sealer needed)

Note: The Cycle X balancer measures inch grams, making our crankshafts and rotors the best in the industry and history.

40+ years later, you now say, "Those Honda CB750s are really smooth running."

For 1969-78 Only

Note: Exchange basis only (Send yours and we'll send you a lightened alternator)
