Cycle X Racing Cam Chain Tensioner

        

Honda had it right the first time (well, almost).  Introducing the Cycle X racing cam chain tensioner. The geometry and design of the OEM Honda tensioner is perfect, except for the upper and lower wheels, which can disintegrate during racing applications and father time. Some of the slipper style designs in the past will cause problems with milled heads or cylinders, causing only the very top of the slider to make contact with the cam chain and the cam chain will also hit the lower metal pin (not good). By design, the lower wheel is very significant to keep the chain happy and stabile by applying slight pressure on both sides of the chain in the lower area of the case.  Designs that eliminate the lower wheel can and will allow the cam chain to slap, bounce and whip in the worst case scenario. Also, without the use of the lower wheel, 8 inches or 25 chain link pins are unsupported.  (In a perfect world, no more than 10 pins should be unsupported)  The upper area of the Cycle X design uses a slipper shoe that adds over 2 inches of added support. So, with the combination of Honda's OEM design, Cycle X's battle tested ingenuity, and using the latest zero friction materials that are unaffected by heat, problem solved!

OEM Adjustable Camshaft Sprockets
(Reconditioned)

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.

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 involved.

So here's 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 procedures (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.
