Cycle X Super Flow Valves
Cycle X super flow valves outperform any valve on the market today. The Nitrite coating is perfect for high temperature, high RPM and run cooler.
The reduced stem diameter (.033) in the port area gives our valves greater flow for noticeable horsepower gains.
 
Cycle X valves are one piece forged, high nickel stainless steel alloy, swirl polished, strict tolerances and Nitride coated. Making our valves the obvious choice.
The first photo shows an aftermarket valve,OEM and Cycle X valve, notice the reduced stem diameter in the port area. 
Light weight?
A complete set of Cycle X valves weighed approx. 30 grams less than the competitions racing valves.
Designed for the preferred 69-76 spring retainers and keepers.

OE Replacement Steel Retainers

77-78 F2 Top spring retainers.
Here is the problem:
 Honda cb750 77-78 K's and especially F2's have the potential of the keepers pulling through the top spring retainers and dropping the valve into the motor. Many people have felt this heartbreak for the past 30 plus years. Honda's later model spring retainers are stamped steel, combined with a steep keeper angle, has only been addressed by complete spring kits costing hundreds of dollars........ until now.
Here is the fix:
 We have been working with Kibblewhite and have developed these top retainers to cure this problem once and for all at a reduced cost.

The photo below shows the imminent damage a valve dropping in the motor will cause.
 

-          CNC Manufactured from high tensile strength steel bar stock

-          Case Hardened heat treatment process to provide a hard, wear resistant outer surface, while maintaining a strong ductile core.

-          Excess material removed from non-critical areas for weight reduction ( 1 gram less than stock per keeper )

-          Designed for complete compatibility with OE components

F2 Fix-Um-Upper Kit

F2 Fix-Um-Upper Kit w/ Bee Hive Springs

ENV-F2B     $449.95

The Problem:
Honda cb750 F Supersport models have several problems with the top ends.
They wear out valve guides prematurely, the valves are unleaded fuel unfriendly, the top valve spring retainers are stamped steel and can pull the keepers through causing a valve to drop in the motor.


The Fix:
Cycle X cast iron valve guides:
Kibblewhite manufactured cast iron guides are made from the best hardened material available. The guides are 49.50 mm in length for added support and longevity.
 
Cycle X intake valves:
One piece forged, high nickel stainless, swirl polished and nitride coated.

Cycle X exhaust valves:
Kibblewhite manufactured exhaust valves received ours and kibblewhites full attention because the exhaust valves and guides are the biggest problem. These specially designed exhaust valves have great flow characteristics and combined with Kibblewhites proven black diamond process makes these valves the best money can buy.

Cycle X valve seals:
Perfect for this combination of valves and guides

Cycle X Retainers:
Honda cb750 77-78 K's and especially F2's have the potential of the keepers pulling through the top spring retainers and dropping the valve into the motor. Many people have felt this heartbreak for the past 30 plus years.

Cycle X Cam Tower Stabilizers!

Why do people install these cam tower stabilizers ? (generally welded)

Well many years ago, high performance Honda people were experiencing broken cam chains. The use of huge cams, OEM chains and 200-plus pounds of spring pressure might have had something to do with it.

Many old-timers thought the broken cam chains were a result of the inner cam shaft journals being .006 smaller than the outer cam shaft journals, resulting in camshaft flex.

Secondly, they thought the cam towers were unstable because they were only relying on the 6mm bolts to hold them down.

Anyway, to modify Honda cb750 valve covers usually consists of drilling the valve cover in the proper location, machining the alloy inserts, jigging and welding the inserts in place. Once the valve cover cooled down, the inserts were drilled and final tapped.

The above mentioned process seemed fine to us................ except for the amount of
extreme heat during welding and not to mention the machine time invloved.

So here is what we came up with !!!

Our Cycle X modification consists of jigging, drilling, tapping the valve cover and installing our inserts. This cost effective, super strong cure for expensive prcedures (without the
extreme heat and machining) is available ......... NOW

If you still doubt us, here's what one of our customers had to say about our modification: 

"Once again you guys are right on the money. Welding on aluminum is not only tricky to do right but actually makes the structure weaker. As a retired tool designer in the aircraft industry we use a LOT of aluminum weldments in tooling for weight as well as common expansion factors since the majority of structure we are holding, positioning, etc. are aluminum. Your fix for this old problem is right on the money, and the price isn't bad either." - Leonard Ledoux

He continues:

"You guys are spot on, putting all that heat into the aluminum casting just turns it into butter. I will grant that 42 years ago it was probably a good idea, but we know so much more today about welding aluminum that it really does relegate the welding approach to the dustbin of tried and failed efforts. Even a machined from billet valve cover would suffer if welded up in the manner usually presented. Your approach is far superior."

Includes:  Modified valve cover. (8) 6mm allen bolts, washers and nuts.
