The 300° stereographic down projection is also known as the little planet projection. Usually it is used to transform a 360°x180° into those famous little planets, but in this example it is applied on a vertical 180° panorama with the last photo upside down:

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.

Don't have back purging, so some sand would just do it.

After:

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.

This is the third version of my custom air filter box for my M72 using a paper air filter C1041.

The previous version with the K&N was OK, but using a paper filter seems to work better with the Mikuni's.

If you found that your code to download from a website started failing with an error like:

The request was aborted: Could not create SSL/TLS secure channel.

or

then your webserver security is updated and now requires TLS1.2.
Tls is a security protocol to transfer data over the Internet. To solve this issue, simply set the security protocol to Tls1.2.

For example in PowerShell:

$webclient = New-Object System.Net.WebClient
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$webclient.DownloadFile($file, $toZipFile)
