Many times people wonder about all the different part numbers for sprockets for the TD and TZ models over the years.

What many of you do not know (I suppose) is that the Hungarian brand of Pannonia used a Yamaha YDS2 to construct their first twin cylinder prototype racers, which later- on led to production bikes. My pictures come from the book:

MOTOR versenyek /versenyzok, by Temesvary Gyorgy and Voros Janos

I wanted to use a modern rear bike lift for my TD1B but did not want to weld brackets or studs on the original rear swinging arm. So I tried to make detachable ones.

With the old Yamaha 's it is always very difficult to re-fit the old and many times hardened rubber manifolds from the airfilterbox to the carburetor.
