Honda SOHC High Performance Camshaft Details
 Camshafts always raise a lot of questions: What kind of performance do you expect? What kind of top end power do you expect?
What kind of riding do you do? What kind of valve relief do your pistons have?
Below are some camshaft profiles you will enjoy without the headaches that monster cams can produce without background and experience behind you.

Here is the problem...

With 11 Cycle X Honda CB750 camshafts and more to come, camshaft installation knowledge would be helpful to your machine shop and to the customer knowing what to buy. 

For example: Unless a "drop-in" camshaft is being installed. The machine shop or cylinder head assembler will need to know which camshaft is being used. Some of the most common heartbreak stories we hear from the public is that a customer had their head ported with oversize valves and all the latest, greatest parts and the valves collided because the the camshaft was chosen lastly. With most "big boy" camshafts, valve to valve clearance and also valve guide seal to top spring retainer clearances are very important but are taken for granted occasionally and a catastrophic situation occurs. The Cycle X high-lift valve guides prevent the top spring retainer from hitting and the valve guide seal from falling inside the keeper groove area of the valve stem and cause potential oil usage. We don't want to get long winded about the well documented procedures with cam clearances and installation procedures. So, here is what we are doing...

We all know why adjustable camshaft sprockets are used in the high performance world. But, stock motor configuration motors can benefit from these also. Have you ever tried to line up the camshaft marks after any sort of motor work or checking a few things? The marks usually never line up perfectly because of many reasons. One of the main reasons on a stock motor with any miles is cam chain stretch. The cam chain is like a rear chain. It stretches. So, install these modified poor man's adjustable OEM cam chain sprockets and realign your cam timing or install your performance cam.
