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.

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.

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.

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? Or a sign? Maybe every other motorcycle is leading up to that one bike. So the sooner I get there, the sooner I can stop trying to get there. So when I come across a Honda CBX in good condition in local classifieds or on BringATrailer, despite the relatively eye-watering price for a motorcycle of the age and mileage, I always think: Is this it? Is it time to sell all the rest and put my money into this one bike? Is it time to make my dreams reality?

Fourth gear is a problem, mostly fixed under warranty by now. These motors require oil changes every 1, miles and filters every 2, miles with valve clearances checked at each interval. This will prevent the infamous cylinder hydrolock. Honda used soft valves in the CBX. They can also burn out with a standard system if the header pipes are not securely fixed into the head and properly sealed. If the carburettors are not set up correctly on these machines, they will never run properly and engine damage can easily result. At over 40 years old it is far from the fastest or best performing. 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. You cannot see where we have done our work and we photograph every stage, proving that the work has been done correctly. Products search. An inherent problem that can be cured completely. Most of these motors require this component to now be reinforced with ally weld in a special jig and then dressing. Chrome stripping must be undertaken very carefully indeed, due to the thinness of the steel. The internal baffles will have corroded, expanded and started to detach from the outer sleeve of the silencer.

Below is a typically well bought Honda CBX The experienced mechanic will know the difference. However, if the maintenance is ignored then the life of the motor is severely reduced. We remove all twenty four valves and associated parts, replace them with new items, grind in the new valves and re-assemble. At its thinnest point that cam chain tunnel is just 8mm thick and the head wants to bow. They are Bandaid fixes even on those machines for which they are relatively suitable. It will never cost so little as the price of parts, labour and servicing will never go down, they will only ever increase and the sooner this work is done, the less it will cost.

It is impossible to see where we have blown in our paint and where the original paint is. They proved to be very shrewd investors indeed, as history has demonstrated. These motors should have oil changes every 1, miles and filter changes every 2, miles. This is an area which is often overlooked but which can be problematic and can require skimming.
