Hello from Norway!

I bought this CB last year and I am in the process of transforming it into a Cafe Racer.
The frame and paint was i pretty good shape, but the rest was pretty tired!

On the jack.

Delivery from DCC! 8)

New rear shocks mounted and overhauling forks!

This did not look good! Good riddens!

Clip ons and bar end mirrors mounted! Oilchange, Valves adjusted, new plugs, plugleads and electronic ignition mounted.

Overhauled the carburettors although they did not look too bad, ultrasonic cleaned and new gaskets.

The seat has arrived, I am very pleased with the look!

I converted it with a built in selfmade led taillight.

More soon!

Acewell instrument installed!

Velocity stacks installed!

Test fitting the Yoshi replica from Carpy! (Loud!) It will be sent to ceramic coating.

Preparing for paint

A coat of orange, also showing off my new Avon Speedmaster/Mk2! 8)

Yoshi back from ceramic coating, looking good!

Time to sync the carburettors!

Seat fastened and bracket for plates in place.

The making of the seatpan.

The seatpan in place with padding and cover.

I added a chrome list on the edge of the tank and seat, to keep a classic feel.

This is how the bike stands today! As you can see the rearsets are missing, the brackets are on the way from Cognito moto so that is next!

Thanks for looking, comments are welcome!

Takker! DTT treff høres bra ut!

Thanks! I think the Yoshi replica is very nice for the price! It is lightweight and looks/sounds great! ;-)

Re: 77 Honda CB550SS

While I am waiting for my rearset brackets I might as well make a shift rod!

Re: 77 Honda CB550SS



Finally a package arrived from Cognito moto!

The gearside was easy and quick!

The brakeside takes some more work.....
Important work! Lightening of the brakeshaft!

Mounted upside/down!

Making a brake lever stop!

Installed!

Next winter I will probably powdercoat these parts black.

It is not an optimal solution, but it will do for now!

Now I wait for better weather, so the testing can start!

Re: 77 Honda CB550SS

Had a little ride today and the bike feels good on the road and corners really well. I have some carburetor work to do however.

Re: 77 Honda CB550SS


So, I have noticed an increasing amount of blueish smoke coming out of the exhaust when warm and idling. Thats not good..... I was hoping to ride the bike this summer and overhaul the top end in the winter. I realize this has to be handeled ASAP! Probably valveseals and/or piston rings...?

So I bought a compressiontester and here is the results....

Procedure:
Bike warmed up, plug out, choke off, full throttle, push startbutton untill the needle stops moving.

What say the experts?

On a lighter note, I got the Tarozzi forkbrace installed.

It is a bracket that is bolted to the top of the rear hoop. its made of aluminium and bent into shape, also holds the rear lamp.

Re: 77 Honda CB550SS

I took a little ride to get it varmed up.

Then i took a compressiontest

Here are the results. First line is the test I took the other day, warmed up by idling only. The rest is from today.

Does anyone have an opinion...?

Re: 77 Honda CB550SS

Thank you, sir

Its time for an overhaul!

Ex port on cylinder 1 wet with oil, the others dry....

The carburetors I will leave alone for now, but the intake manifold will be matched to the top.

Valve tappets on intake side cyl. No 3 and 4 looks shot...

Camshaft out!

Top of!

Looks like it is running lean....? No surprise....

The chain tensioner works and looks ok....?

Looks like the piston rings has made some nasty marks in the cylinder walls....

Day 1 is over and the 550 is spread across my garage! ;D

Re: 77 Honda CB550SS

Anyway....

Today I took off the cylinders and took the head apart.

The pistonrings looked ok and were loose.

I used a little magnet to take of the valve retainers.

As you see the no. 1 ex valve is missing.... I cant get it out of the head, it is bent! The no.2 ex valve was bent slightly also, but I managed to get it out.

There is definetly room for improvement here!

550 cam clearence.....

650 cam clearence....

Cylinders from 1-4

To sum this up :
I have got two bent valves, 1 and 2 exhaustvalves. My guess is that the stiff valveseals became oval shaped, hence the blue smoke?
Cylinders are not looking good?... How do I know when to hone and when to bore?
The valves had a minimal play from side to side, is this normal or do I need new guides?.
Strange that it was not the tappets on the bent valves that got destroyed...?
