Signs...

My life ain't just the Speedshop, I also need to keep the cashflow balanced.
The money can't just roll out when buying parts for all the toys in the Speedshop so a day job is required.
And to save up the extra cash a brought lunchbox is one way to save up.
But a sign that I'm on the right path revealed itself one day in the lunch box...

Intake Air Temperature

Another thing that needs to be monitored is intake air temp.
First made a hole in the air filter bracket.
Then I welded the supplied stainless bung with the TIG. A not so challenging task but it had to be done. And after that it was just to thread in the IAT sensor.

Cylinder Head Temperature

More sensors. This time the CHT (Cylinder Head Temperature) sensor was next in line. The bike actually came with such sensor when new.
But now it was time to upgrade it more post millennium standard so the EFI system get the input it needs.
Autometer had a sensor that seemed to fit, so I ordered one from US.
When it arrived it was just what I have been looking for.
But the mounting hardware was not solved.
I made a aluminum spacer and than a nut with 1/8" NPT thread.
It paired up nicely with the stock hole in the rear cylinder head.

Size comparison

The nut made and ready for assembly

The final mount

Fuelrail - the end.

The Fuelrail didn't turn out like I wanted so another one was created, but this time I put much more love, time and effort. And now it turned out great.
A quick tour to get it zinc plated to protect it and give it the shine it deserve.

Fuelrail - the beginning.

This project became longer and more labor intensive than I hoped for.
I started with some square pipeing and bungs. Actually the square piping I had over from the dog cage project and the two bungs I made in my lathe.
And it started like this.

The main unit.

First job with the injection system was already made when the project went from Sportster to Bigtwin. Buying the EFI system.
I bought the system for the Sportster but when I ordered it I bought another wireharness. Just in case for the Bigtwin and that day came faster that expected.
I went for the DIY open source EFI system, Megasquirt.
This system have a quite large ECU so I went for the already assembled smaller version, Microsquirt.

The eighth winter 14/15

The eighth winter was originally intended for my new project, a custom Sportster build.
But things happens and friends pushed me in other directions.
So this winters lineup are for the old Shovelbagger:
# Completing the seat.
# "Noseart" on the fairing.
# And the main project, EFI.
It was time to take my old comrade in to the twenty first century with some Electronic Fuel Injection.
The EFI job have so many stages so each one makes a project of its own.
The updates will not always be in the right order either.
