Gaskets, Guzzi's and old Kawa superbikes

Last time I replaced the contact breaker points I noticed that the original gasket (I believe still from 1977..) had shrunk and didn't fit anymore. I looked up some decent paper and copied the ancient parchment.

Klaas had noticed that the tyres of his Guzzi 750 Nevada started showing cracks! The back tyre is from 2004 (the front looks like it's from 1886..) Both will have to be replaced so i started to remove the wheels from this Italian cruiser.

The last pictures are from a ZXR750 that I spotted in Heemskerk a few weeks ago. I will always have a soft spot for this classic superbike. This example was very well used (not abused) altough the pictures don't show it well.
