October 6th, the NBA is playing in the Seattle KeyArena. Golden State Warriors vs Sacramento Kings in an exciting pre season game!
Five 12mm shots were enough to capture the whole arena, before construction begins on the $700 million renovation.

One the way back, a view on the newly renovated Space Needle in the moon light. This was just one 12mm shot.

The 300° stereographic down projection is also known as the little planet projection. Usually it is used to transform a 360°×180° into those famous little planets, but in this example it is applied on a vertical 180° panorama with the last photo upside down:

Gets you this amazing view:

Cityscape is constantly changing and over the weekend I took a snapshot of the Seattle water front.

With the custom air filter and new carbs, the standard intake pipes do not fit and the aluminum - rubber combination looked ugly.
Make one :)
Using a 90° and a 45° stainless steel elbow with 3mm thickness seemed to be a good start.

When back purging is not available, just use some sand instead.

The Mikuni carbs do not have a vacuum port to sync carbs.
Carburetor synchronization is important for a smooth running engine, and if you follow the simple steps, you can easily add a sync port to the Mikuni carbs.
The flat spot is perfect for the connector port.

I made the connector out of bronze with M4 on the outside and M3 for the cap screw. Use a 3mm or 1/8" drill bit for M4 as this material is very soft.

Depth is about 5mm.

The outside diameter of the connector is 4.5mm.

Connecting a simple vacuum gauge shows the negative pressure for each side. Use the idle adjustment screw to set for an equal value.
