The gas tank was leaking tiny bits of gasoline. I didn’t notice for a very long time as it was sucked up by a rubber block. At some point I noticed that the rubber block was twice as big as it is suppost to be and over some time very small amounts of gasoline dripped to the ground. The source for the leak was on the bottom of the gas tank, where the brackets for the antivibration rubber blokcks are welded to the gas tank. Obviously the metal of the gas tank was weakend by the welding process so it leaked after about 50 years later.
So I went to the a welder company and they laser welded around both brackets without even damaging the paint. It’s now sealed again and probably good for many more years.

Litte ride out with a friend. This is somehow an interesting picture as the bikes are so similar but on the other hand so different.
In front the european interpretation of an “Aermacchi” as sports bike with a light frame and without electric start. In the back the US interpretation of the bike as a two-seater vehicle with a large seat and electric starter.

• 06/16/2013: First oil change at 120 miles (193 Km) – out HD 20W50 – in Castrol 20W50
• 06/19/2013: Re-Tightened nuts and bolts. Impressive how many became lose after that short period.
• 06/30/2013: The plan was to attend an oldtimer get together and market in Ansbach (mototechnia) which is about 35 miles from my home. I made 2/3 of the way, when suddenly the engine cut off (odometer: 160 miles). Luckily that was very close to Aermacchi parts distributor Rudolf Jungjohann. The error was found quickly: The circuit breaker screw came loose and was damaged, so I had no spark at all. We put a replacement screw in adjusted the timing and the bike did run again. Sadly there was no time left to attend the get together anymore on this day, but I did make it home on the bike without trouble (180 miles)
• 07/07/2013: Believe it or not – the kickstand broke into two parts just out of nothing. (odometer: 213 miles / 342 kilometers) Luckily this happened while in my own driveway and still sitting on the bike. Imagine what could have happened, while the bike resting on the kickstand!
  
• 07/08/2013: As I can’t ride the bike at the moment because of the broken kickstand, I decided to disassemble the right engine cover again to replace the oil seal for the clutch hub. Reason: I am losing tiny amounts of oil through the dry clutch. This happens because of my own stupidity, I mounted the oil seal with the wrong side facing the oil. I realized that by looking at pictures I did during assembling the engine.
• 07/08/2013: Replaced the tach drive because of a worn out oil seal. I had a NOS one at home already, because I expected that problem.

Finally back on road. I also bought myself a matching italian-flag-design helmet for the bike. 🙂
