Hi, Finally I managed to fix the issue by replacing the "part" on the wheel (found a NOS at reasonable price), cable and replica speedo. I have my original speed which I have been told by an Italian specialist which cannot be repaired (the bushing is worn out). I was reading that Al Marsha...

Hello,

Is the case-assy speed gear (part n 41078-001) same for miles and Kilometers?

Thanks

is there anyone who wants to sell the whole case-assy speed gear (part n 41078-001).
thanks

I had the same thought but what should I do to rectify?
ciao

hi, I am Alessandro from Italy, owner of Z1b 900 (1975) My speed in KPH has a needle oscillating a lot above 60 kmh. I ha been told by a specialist that it could not be repaired. Then I bought a new speedo from Dave and I installed it. I had to file the frame because the replica is not fitting on th...

Hi, I am Alessandro from Italy. My Speedo is not working properly since years. The needle is shaking tremendously above 60-70 km/hr.
I have ordered the bumpers to reduce vibrations.
I understood that Al Marshall is a magician of Speedo.
Kindly share contacts of Al.

Thanks

Hi,
Are you sure the the plastic reservoir is threaded and not installed by pressure?
Thanks

Thanks.
I am trying to anodize.
I know the guy who is anodizing stuff for Rizoma and he is working very well.

thanks z1bman. this is my master cylinder of z1b I did read a lot of threats and it seems to be very difficult to remove the plastic reservoir without damaging it Any suggestion?

Hello, I have one question for you expert. I want to restore my front brake master cylinder of my Z1900b, 1975. The colour is now a sort of violet. I believe in origin was black. I would like t know if it was anodized or painted. Which was the finishing? Glossy, semiglossy or opaque. Thanks and Rega...

Suddenly my headlight is not working.
Bulb is fine.
I don't get 12 v at the two wires, both low and high beam.
Position light (the small one) is fine.
Any suggestions?
What should I check?
Thanks

At the end I found a very good mechanic.
6 valves was bent.
Work has been done properly.
Carbs have been cleaned as well.
Now bike is smooth like silk.

no real alternative.

Do you believe that such clearance increase means valve bent? We are talking about 0.30 clearance increase.
Which are the risk to fire the bike and test compression?
Thanks

With 305 I should have 0.1 clearance. Am I right?

Ciao

Thanks for your valuable suggestions. Yesterday I managed to install properly (I believe) the cam shafts. I have checked the clearance and I am afraid that one valve has bent. I am talking about intake valve cylinder 4. Before it was clearance zero with 280 shim. I put 270 and now clearance is 0.45....
