Why are our Honda CBXs so good? Below is a typically well bought Honda CBX

The Honda CBX is a very special motorcycle. At over 40 years old it is far from the fastest or best performing. Even at its debut it enjoyed king-of-the-hill quarter-mile status only until the Suzuki knocked it off its tenuous throne merely a few months later. Heck, with its origin in a s NSU design its multivalve multi-cam engine was already old tech before it was even produced. So no one has illusions, not then and certainly not now. And heavy? And wide?

So as I am sure you already know or will soon find out that the alternator on the CBX is its biggest Achilles heel, the alternator itself is a fairly common design and is reliable contrary to popular belief, a number of its fellow models and contemporaries also used this design in without issue. This issue revolves around its drive system which employs a pair of steel clutch plates, these clutch plates wear for a variety of reasons not for this knowledge base , however a key one you must check is the oil restrictor, this either comes loose with the oil pressure pushing it against the alternator shaft restricting lubrication and cooling or secondly, it also can block at the rear as shown in the photo so please ensure you check this by starting the engine with the alternator removed ensure all the usual safety checks before doing this have a pot ready! The friction on the B plate transfers down the rotor shaft and causes the oil seal, bearing and rotor windings to fail. Machining of plates should only be undertaken if the plates are scoured beyond lapping on a surface plate or piece of plate glass. Both plates have been hardened using induction or case hardening to a depth of around 0. The drawing is below to undertake this process yourself, we do not warrant this process and it is undertaken at your own risk. The other issue is the spring length, this needs to be a minimum of These are easily examined by removing the front casing once the alternator has been removed from the bike, to do this unclip the 6-way connector behind the right-hand side panel and tie a piece of wire to the plug so you can pull it back through on refitting. Remove the three bolts that attach the alternator to the engine casing 10 o'clock, 2 o'clock 6 o'clock If the front casing does not easily come off after removing the 3 bolts apply heat using a heat gun to the centre of the case where the outer bearing sits, it should drop out after applying heat. The brushes once the casing is removed are clearly visible and should be in excess of 6mm above the brush holder, if not replace them hopefully no explanation is required here on how to do that. Be very careful when refitting the six bolts not to overtighten them as the casing easily cracks if they are overtightened. Measure across the two copper slip rings, you should expect to see a resistance of between ohms both on the US and European variant of the alternator. The alternator will work quite happily at 3. Also, note that the resistance can drop right off when the bike gets hot, you can check the resistance through the white and black wire in the 6 way connector. Stator The three windings on the stator three yellow wires going to the regulator from the red connector need to have a resistance of between 0.

We also recreate the correct level of shine and orange peel finish in our paint, so it looks like the original cellulose paint from the factory. We ensure that our machines have original Honda CBX exhaust systems, honda cbx 1000 probleme, standard indicators, mirrors, airboxes and all those impossible parts to find. Then a compression test, to see if there are any other problems or bent con rods.

A Honda CBX engine rebuild is not something that should be taken on by a home mechanic in their shed or garage. These motors are unique, quite complex and there is a lot of knowledge required about how these engines work and are put together before touching them. The time has come to rebuild these motors now because the cam chain tensioners are at the end of their life. To change the cam chain tensioners the entire motor needs to be stripped to the last nut and bolt which offers a great opportunity to really understand the history of the motorcycle and fix anything that requires attention. These motors require oil changes every 1, miles and filters every 2, miles with valve clearances checked at each interval. Thinking you can just check them every 8, miles is really not acceptable and could cause the bike to drop a valve or two.

This story was originally published in the June issue of Rider Magazine. This was a minor marvel of motorcycling when the original version was unveiled in as a model, more than 40 years ago. Six cylinders, six carburetors, 24 valves, two overhead camshafts and more than crankshaft horsepower—the CBX Super Sport was going to dominate the sport bike scene. Unfortunately, it did not. For the first two years it was stripped down, then transformed into a sport tourer for its last two. The focus of this little write-up is on its touring pretensions. Begin at the beginning, which was in October of , when Honda discreetly snuck some test bikes into California and had a few American journalists come and try them out. Honda had introduced the original UJM back in the fall of , the CB, with four cylinders, eight valves, overhead camshaft and 67 horsepower, weighing some pounds.

It was as vivid as any dream I can remember. I remember the engine head sticking out the sides. I remember the purtle of the exhaust at idle. I woke up and thought: ye gods, was that a premonition?

They are Bandaid fixes even on those machines for which they are relatively suitable. Below is a typically well bought Honda CBX Now is a great time to change the primary chain, as these are still available and are critical to safe running of the CBX engine. They can also burn out with a standard system if the header pipes are not securely fixed into the head and properly sealed. The only way to properly check is to remove the alternator which is an easy job done in the frame and check them with the best method known to man - eyesight!

The Honda CBX is unique as it has specific weaknesses such as con rods that appear to be made of chocolate and have a tendency to be bent. Functional Functional. High performance brakes aren't the answer. The bottom of the cylinder block and the crankcase mating surface to the block need to be checked for trueness. The engineers blue shows where the head will start leaking. Clutches tend to be noisy and many parts are no longer available. Remove the tacho drive first and ensure that the thrust washer shim is removed first, then the taco drive and then remove the rocker cover. This is normal wear, but Honda introduced an improved chain, ie the top chain that joins the two camshafts for longer service life.

On early engines the track on this gear was not machined correctly and wears rapidly. All twenty four valves must be checked by an engineer. The Honda CBX is a great classic motorcycle investment. Honda CBX barrels need to be checked for being true across the head mating surface, this is usually not a problem but has been known to be in some cases. The chrome will have protected the steel from corrosion on the outside, except for where the old lead acid batteries vent on the right hand side of the motorcycle. The new one has adhesive around the oil gallery holes and around the cam chain tunnel. Should this piece break, which they often do, there is a good chance that the taco drive will find its way through the cylinder head. Draining them. He checks the valve guides for clearance, as he has the equipment to do so, and has the equipment to cryogenically switch out the guides for new ones if necessary. In a recent year, two out of three CBXs in my shop had melted igniters.
