THE HIGHEST LEVEL

( Its about time ) New carburetion system for Honda 750 SOHC

                                           Item Description

QUESTION : Tired of your stock, leaking, lean popping, misadjusted, old looking carbs?

QUESTION : Why do stock carbs make that annoying sucking noise while driving down he road?

ANSWERS : Eliminate these problems with our NEW carb system, prejetted, DYNO tested, best looking carb system hands down.

We designed this carb system for easy maintenance and looks. Dyno testing was done for the proper fuel and air mixture. 
Our test bike had 44+ thousand miles on it. Gave it a mini tune up, and we went from 51 HP to 58.8 HP.(rear wheel)
Same bike, Same gas, Same gearing, etc...
Did we mention that stupid sucking noise is gone?
We are here to help you with questions. E-mail with basic questions or call Ken for details at # 715-356-7346.

NOTE: We are working on a high performance version of this system. (836 cc, cam, fully ported head)
Apparently some of you want to go 150 miles  per hour on your chopper.
This system is 12 months in the making. It is REAL!

ATTENTION: We will only be selling the Econo Carb Kit. The choice of are filters are listed
                                           below and will be sold at additional cost.

 " The CycleX carb system is the best new product developed in 30 years. Simple, Dialed in and priced right. We wouldn’t even consider anything else. "                                                                                                                                      Jeff Zeller, Custom Choppers Inc.      ( Boulder Junction, WI )

" The CycleX manifolds with Mikuni carbs are better than any of these modifications ( Individually or collectively. )  Velocity stacks, straight pipes, cam, larger pistons.  They're easy to install and the quickest way to get massive horsepower gains."                                        Rick Hoover        ( Saint Charles, MO )

"These carbs and manifolds are nothing but the best! The service you get from Ken is even better. There is nothing I know that compares. If you are thinking of
buying them, don't hesitate. You will not be sorry. The performance is truly real and not hype."  
                                                                                                                                        Stacey Glenn Barnard ( Bainbridge,NY)                                           

 " The difference between Ken's Carbs and stock is UNBELIEVABLE!  This motor has never run this well since I first put it  together!"

                       Jetting on the fly !!!!!!!!         
             

This extra gas circuit has many benefits.

Completely adjustable external jetting system. 
Delivers pre-atomized ( vaporized ) fuel for maximum horsepower. 
Has enough external adjustability for any altitude, temperature or engine modifications.
Float levels can be checked at a glance.

* fast and easy tuning     

* increases horsepower

* improved fuel efficiency

* quicker throttle response

* billet aluminum construction

* delivers pre-atomized fuel to the engine

* has no moving parts or electronics to fail

* compensates for altitude and temperature

This device is an advanced fuel circuit that may be adjusted manually through its precision needle valve.  

This device supplies 10% to 15% of overall fuel in a pre-atomized or vapor state.  It has its own fuel mixing chamber where air and fuel are properly mixed and per-atomized (vaporized).  Fuel is drawn into this chamber from the float bowl, then united and swirled at high speed with air from the air correction circuit, thus vaporizing the fuel.  This vaporized fuel is then inducted into the carburetor.  This fuel weighs only 10% of what raw fuel weighs.  The light weight of this fuel charge allows quick response to slight changes in engine fuel demand (engine load). You will have quicker throttle response, a broader power band, improved fuel efficiency, cooler running engine, longer plug life and excellent burn down protection.  The fuel induction is controlled by engine vacuum, air flow, and acoustic sound signal,.  The heavier your engine is loaded the more fuel  this device feeds.  When engine load decreases, so does this device's fuel flow. 

You now have a demand feed fuel induction system that feeds fuel linear to engine load.

                Poor mans jetting kit
This extra gas circuit procedure has been done for years.
Carburetor jetting is an on going topic of discussion.
So, here is what we do from time to time.
Tap into the float bowl and insert pilot jets into the throat of the carburetor.
This procedure will give your bike a boost from  approx 1/4 to full throttle. 
Also, it will allow you to check your float level at a glance and purge unwanted sediment from your bowl.  

Kit includes
Drills.
Taps.
Jets. ( 2 sizes )
Fuel fittings.
Fuel line.

Ever wonder why some bikes run better than others with the same components?

Why does my buddy’s bike have this jetting and mine doesn’t like that jetting?

For conversation sake, lets assume (Never assume.) that both bikes are in the same condition, same electrics, tuned up, altitude, etc…. (Mileage unknown.)

Why do some bikes require different jetting?

 Story:

 We had a customer’s motorcycle that began to run rich. All the normal tune-up stuff was ok.  He is the original owner and no changes were made. (Exhaust, fancy air filters, etc.) 

Question: So why does the bike run richer?  Failing ignition?  Dirty air filter?  Float malfunctioning?  Bad fuel? 

Answer: Worn carburetor needle jet and needle.

 Just like pistons, carburetors are working hard. Slides are moving up & down, being pulled & pushed with intake pulses constantly wearing the inside of the needle jet.

The needle jets and needles are very precise and wear is immeasurable. The detection of this problem is sometimes difficult. (Unless you spend a $100.00 per hour on a Dyno.)

When you drive a bike at normal speeds, you are generally in the pilot circuit, slide cutaway, needle jet and in the needle a bit. These circuits work together delivering fuel to your motor. A little wear in the needle jet and needles is why some bikes with open exhaust, open air filters SOMETIMES run better with almost stock jetting. We wrote a tech article on exhaust systems and tuning and basically said: Select an exhaust system you like and jet accordingly with an open mind. Same with this needle jet, needle topic: Do not go into jetting a bike with a preconceived idea about jetting. Keep an open mind. 

We do not know if needle jets & needles are still available or if you really need them.

This was just a story and maybe this will help someday.


Here is what do from time to time.
Consider the needle jet like a drinking straw.  
If you poked a hole in the straw, you would get a lesser amount of soda and a bit more air.
In a carburetor, you would get a bit less fuel and a bit more air ( atomized somewhat )

When the needle jet wears..............We install air jets so we can regulate the amount of air entering the needle jet.
This is another "external " method to make these old carb's user friendly.
