The other HD...

My other project I have is a custom Sportster build.
This project is over a decade old but it got my attention again when I finally got my hands on an engine.
But just as the project re-started it had to stand back again last winter when the Megasquirt EFI conversion of the shovelhead suddenly started.
But this year it's just small upgrades in pipeline for the shovelbagger so from now on the girlybike will have the attention it deserves.
This bike is basicly just a tiny frame and and a Sportster engine.
But why a tiny girlybike for a 300 lbs, 6' 3" guy?
Why not? If it is reasonable there is no future for a project in Bombus Speedshop.

I think this is a good base for a never ending project.
This bike is way to small for me but will be a nice complement to my big bagger.
The plan is wild and will have a high tech level.
Way to high for a build like this, but that's half the fun.
Think A to B Hot Rod is a good description. "built to handle nothing".
To much is the key to long projects, and long projects is the ones I likes best.
In the end this small gem will have both Megasquirt EFI and turbos. Yep, plural.

Logging

As I mentioned earlier I can log the EFI system with a PC and not just standing still.
I can also "autotune" while driving.
Not so challenging task in a car but on a bike there's another matter.
I made a mount on the tank where I mount my PC, a 10" mini laptop.
The mount is made with a special Velcro® and have three mounting points.
Started with two but I added another for more rigidity after a while.
It's just a 10" laptop, but there is still a challenge but that's a part of the thrill.
I started with a "regular" laptop but that one decided to crash just before the first start.
This resulted in the project went to full blown computer project due to the fact that all EFI files was on that computer. So I had to shift focus and try to get those files out.
I had success with the file rescue and a search for another laptop begun.
The first one was kindly donated by my friend Wiking Cycles and he rescued me again with the mini laptop I have now.

Second start

The first start made my adrenaline flow so extreme so I completely forgot about logging the EFI system.
The next day it was time for another try, this time with adrenaline at more normal level.
By judging of the massive smoke it was a bit left until I could hit the road.
This solid cloud was the result of about just a minute of idling.
But this time I got a log so facts could been seen and relevant changes made.


Bling

Some bling was required when the EFI made the mighty old shovel roar again.
Ladies and gentlemen, the Bombus Speedshop point cover.


First start

So finally the D day was up!
(Actually a while ago, in middle of April.)
I was so stressed so there was no thoughts whatsoever to film this moment.
But all thanks to my wingman Feeler Cycles this super stressed and confusing moment went in to eternity.
This moment is definitely on my top 10 adrenaline list.
But even if the engine went rough to say the least this first time my smile in the end say's it all.
