Another motorcycle parts repair thread

[Fazerruss]

This time it's broken fins. First one is an old Triumph possibly T120 cast iron twin cylinder. This one had two broken fins. One was on top bit the other was a more difficult one between. Cast iron is tricky to weld so I brazed on the replacement fins. Even then it's still difficult especially getting in to braze a middle fin.
The second cylinder repair was a Yamaha RD 400. There were two broken and several were bent.

Fin repairs are a complete dratsab.
Die -cast Gold Star cylinder barrels are incredibly fragile, and no matter how much care is taken , they can frequently fracture thereafter in use.
That, I know....

I found some photos of a LYTA tank repair I did earlier this year.
