Hello Nigel and Julie
this is a very long story.
My first  Bike was 1975 a cb 400 four. Two years later I sold.
In the meantyme  I had a lot of different Bikes and a long nothing.

8 years ago I thought about a new, used cb 400 four at ebay.

I´ve done everything  by myself. Only the Motor a specialist had done.

After 500 Km  , when I start the cold engine it smoked blue for nearly 5 minutes.
When the motor reached Temperatur there was nothing.

The specialist changed once more the piston rings. To original Honda!!??

But after 500 Km , the same procedure. Smoking like crazy.

I was so angry, Iwould like to sell this Honda.

Then I had an Idea. In the near of my City is an old Honda dealer, I contacted him.

He has now putted in Pistens, rings.  0,75 .Everything original Honda parts.

I brought him the disassambled Bike. He opend the motor and was looking everywhere.

I hope, now everything is now okay. This bike was until now very expensive. Incredible.

It´s a pity, the weather. Okay it´s winter. Therfore it stands in my flat.

I will put a few fotos without comment.. They show the motor  Inside after 500Km.

Regards

Rudi, now and 1976
