New Valves, Guides, Surfaced, Valve Job with Cycle X Bee-Hive Spring Set

This set up is for hot-street life.

This Honda CB750 SOHC head will fit on all 1970 thru 78 "K" models. It will also fit 77-78 "F" supersport models with a few changes here and there. (Give a call)

This refurbished head's parts includes:
(8) Cycle X superflow valves.
These Cycle X valves are a one piece forged high nickel stainless steel alloy, swirl polished, made to strict tolerances, and Nitride coated.
The Nitride coating helps to run cooler in high temperature and high high RPM applications.
The reduced stem diameter (.033) in the port area gives our valves greater flow for noticeable horsepower gains.
Designed for the preferred 69-76 spring retainers and keepers.
Note: Refacing old original valves is not recommended. 

(8) Cycle X / Kibblewhite cast iron valve guides.
Kibblewhite manufactured cast iron guides are made from the best hardened material available. The guides are 49.50mm in length for added support and longevity. These guides are used by some of the top engine builders around the world.

Cycle X bee-hive valve spring set.
We worked hand in hand with Kibblewhite to bring you theses Bee-Hive kits specifically made for the SOHC bike. Unlike most springs out on the market today, that have a "generic" spring rate, these were designed with spring rates that work best with Cycle X, Webcam, and Megacycle cams.
The advantages of this system has been known for many years and are documented through-out the internet for your reading pleasure. The weight reduction when opening the valve (top collar and half the spring) is about 27 grams per valve less than stock. This weight reduction will result in instant RPM's and horse power that can only be previously achieved by expensive thin stem valve kits. Now all the same great quality at cheaper price to keep you and your wallets happy!



Labor and machine work includes:
All refurbished head procedures include glass beading and inspection.
After the inspection, the valve guides are removed and new guides are installed with our Cycle X procedure. The guides virtually follow the same path and makes valve jobs a breeze. Many machine shops use drifts to remove and install guides. Drifting in valve guides can cause 2 problems. First, the valve guides never seem to follow the same path in the head as the removed guides. Second, the inside bore of the drifted guides can cause a "S" bend on the inside. This "S" bend problem is generally seen on bronze guides installed with a drift.

After reaming and honing the valve guides, the seats are given a multi-angle valve job to manipulate the lapping line or contact area where needed. Once the contact area is in the desired area, the valve job is finished off with a 75 degree cut angle approx. .240 deep on the intakes to greatly improve flow. This area of the seat is the most important and is used by top engine builders in the auto and motorcycle industry.
Finally, The 45 degree is touched off with 150 finishing green stone. Once again, used by top engine builders.
The head is then surfaced to insure flatness and head gasket sealing.
Clean, install valve guide seals and bee-hive spring set

Machining Excellence!

 

 Refurbished, Freshly Machined 970cc Cylinder, Gaskets and Wiseco 970cc Pop-Top Piston Kit (K and 77-78 "F" Models)

These Cycle X designed and Wiseco manufactured pistons are super light and have been coated with the Wiseco armor-glide process.
Depending on your cylinder heads combustion chambers, these pistons will be around the 12 to 1 compression ratio area.
This 12+ compression ratio is a must when selecting higher lift and larger duration camshafts.

Included in the cylinder and piston kit sale are the tested, developed and funded MLS viton coated head gasket and steel viton coated base gasket.

The cylinder has our complete big bore machining process done.
Remove the old cylinder liners.
Glass bead the cylinder block.
Surface (mill) the bottom side and machine "O" ring grooves to prevent oil seepage from the center of the block.
Bore the cylinder block for the larger sleeves. Hone the cylinder block to exact dimensions so the cylinder sleeves install happily.

Note:
Back in the 70's era, machine shops would only bore the cylinder blocks (not final hone).  By boring the block only, the finish is not perfect and we found after miles and miles the sleeves can loosen up a bit.
The new sleeves were installed, bored, honed, surfaced and heli-coils were installed.

Strong in Performance!

 

Refurbished 915cc Cylinder and Pistons

This cylinder has been just completed with our 915 sleeves and pistons.
The re-sleeving procedure consists of removing the old sleeves, boring and honing the alloy block to size. Pressing in the new 915 sleeves and surfacing. Boring and honing the sleeves for piston fitment.
Note:
Our sleeves allow the use of "O" rings at the bottom to prevent oil weepage.

The Cycle X designed Wiseco manufactured pistons are our favorite kit.


Note:
People talk about oil weeping upwards and and out the fin area when installing bigger sleeves. Well, we have seen many cylinders that have had this problem and after looking closer at the machine work We can see why. Most of these weeping cylinders have the alloy block bored (not honed afterwards)  which leaves a boring bar machine finish allowing the oil to have a easer path upwards and eventually can loosen the interference fit.
Our cylinder alloy blocks are bored then honed to exact clearances with a fine finish before installing the sleeves.


Includes:
Reworked cylinder.
Coated 915 pistons. (Complete kit) rings wrist pins and such.

NOTE: Out of stock momentarily. Currently machining more. Stay tuned!

Smooth and Strong!

 

Honda CB750 Lightened and Balanced Crankshaft

Lightened and balanced. Not to much, not to little.
This crankshaft is our most popular.
Micro polished and balanced with our second to none balancing procedure.
Note:
Many crankshaft folks do not remove the ball bearing blind hole plug that will trap 40+ years of sludge. We remove the ball plugs and clean.

Easing Rotor Performance!

 

Honda CB750 Lightened and Balanced Rotor

These alternator rotors have been lightened and balanced to perfection. (Not to much. Not to little)
We have seen stock rotors and lightened rotors from the 70's era off as much as 12 to 14 grams.
So, let's say you went to expense and effort to balance your crankshaft and your rotor hanging off the end off your crank is out off balance worse than the crank.
Yes, your charging system will still work.
