Engine Parts Clutches

"I just want to thank Ken at Cycle X for all his assistance with my clutch problems. I had a Barnett extra plate clutch, and although it didn't slip, it had jerky and noisy engagement. I tried a different clutch and that engaged smoothly and quietly but slipped in the upper gears. Cycle X 6 spring conversion cured all these problems. I've attached some pictures of my bike. Thank you."

The Ultimate Clutch Kit!
New 5 Plate System

Why is this the "ultimate" system?

We've corrected some of the problems with the Honda CB750's and included high-end products to complete the kit. We have continued developing the Cycle X system and people are raving about the 5 plate system.

1) Includes a billet lifter plate. You know, the plate that breaks when you are tightening the springs. New lifter plate bearing included.

2) Includes the proper spacer, steels and frictions. This arrangement will keep the friction plates away from the alloy OEM clutch center and pressure plate. No more chattering, grabby, noisy and inconsistent operation.

3) Speaking of high-end products, the kit includes Barnett steel and friction plates.

4) EBC medium pressure springs to keep your left hand happier.

5) Cycle X "no leak" clutch cover gasket. Super quality!

6) Bolts and oil seals. You might need them.

Guaranteed satisfaction.

Can't tell if you have an early or late model? These instructions should help you identify.
Early is 1.460 clutch pack thickness. Late is 1.560 clutch pack thickness. (Steels and frictions combined thickness.)

New Six Spring Honda CB750 SOHC Clutch System for High Horsepower Applications

The six spring, seven friction and steel clutch system is a bolt-in upgrade for your Honda CB750 SOHC hot rod.

6 spring pressure plate with new bearing.
Inner clutch hub "modified".
Outer steel clutch hub "modified".

"Well, as usual, Ken is the all knowing guru when it comes to anything CB related. I called him a month ago to see if he could help me with my clutch dragging problems.

No matter how I tried to adjust my clutch, it always dragged when I pulled it in. This made life unpleasant at stoplights and in traffic. The bike always wanted to pull forward and if it wasn't rolling, finding neutral was next to impossible. I tried to remedy this by adjusting it with no slack in the cable, but that made it slip under heavy load and still refuse to totally disengage when I needed it to.

Ken pointed out to me that Honda had some issues with their clutches in the 70's and they had done a number of things to try to correct them. One thing they did, which my clutch had, which my clutch had, was this funky double steel riveted disc in the middle of the stack. WEIRD! Ken also pointed out that Honda put friction discs on the outside of the stack, making contact with the aluminum basket.

Anyway, he suggested that I try his four friction disc clutch with coated steel discs and machined spacer. This reduces the number of friction discs from seven to only four, but retains a count of five steel discs by leaving two steels on the outside of the stack so the friction discs do not touch the aluminum basket. It also eliminated that one strange double steel from the middle of the stack. The kit also included eight spring shims which I installed because I have a hot rod motor built by Ken that puts out nearly twice the stock Honda HP. The shims obviously increased the length of the springs to make up for the newly found room in the clutch basket. I thought this would make it harder to pull the clutch in, but I honestly can't tell the difference in the pull at all.

Of course I worried that the clutch might not be able to hold the load of me and my 90+ rear wheel HP Cycle X motor without slipping. No such problem.

I put the clutch in on Friday afternoon and rode about 400 miles over the weekend. I tore up the twisties and did a few high speed runs, including a couple 110 MPH + blasts with no clutch slipping. Now when I pull the clutch in, it disengages and allows me to find neutral with ease, whether I'm rolling or at a complete stand still.

I am now enjoying perfect clutch bliss and serenity. Less friction plates equals less stress. Thanks once again for putting my Honda world back in order."
