1975 Honda CB400F review from Belgium

Cam chain problems: slipper was complete worn (ever replaced?). I have changed the cam chain guide and slipper, and will replace the cam chain. Also replaced plugs (were in a terrible state!), contact points and capacitors.

I had some difficulty finding the best front fork oil, and now I use a mixture of 1/3 ATF and 2/3 20W heavy Fork oil (was recommended to my by a Honda Service dealer, but proved to be to 'heavy').

Main head light is also a problem: too weak and the generator does not deliver enough changing current for more powerful 55/50W or 65/60W bulbs. The problem is solved by replacing as many small lamps as possible by their LED-alternatives and saving so 40% on the current.

A very nice and attractive bike. Gets some attention, especially from older bikers.

It's still quite reliable, and up to going with the present day traffic.

I would not recommend to use on highways with fast traffic, but country riding is very pleasant due to the very good handling. It is not a 'simple' bike: you have to 'feel' when to switch (six gears!), when and how to brake, when to accelerate, but the bike gives you in return the 'real motorcycle feeling'.

Parts are still available in NOS, new replacements or second-hand. If possible, look for a spare engine and carbs at a reasonable price, so you can look how things fit to together and you can experiment before trying to repair/adapt your bike.

Have fun with it!

PS The bike is still sought after to rebuild it to a CR (Café Racer), see Yahoo CB400F community group.
