Dellorto dynorun

Now I was ready for some serious tuning.
After a while with lots and lots of short test runs I had a Dellorto set-up that looked amazing and with reasonable driveability. The next step was to do the final tuning on the dyno.
The third time around on the dyno for this bike. First: S&S, second: CV and third: Dellorto

On the dyno with the Dellorto, at last

But it took untill autum 2013 before I got to do some dynoruns with the Dellorto.

Because I had to do a cover for the "wire wheel" and solve a problem with a sloppy return spring first and of course solve the dreadful problems that turned out to be the loose valve seat.

So I had to go back to the trusty old CV for a season (2012) to pass technical inspection and to get a proper dynorun on that carb also.
But now the problems are solved and the mighty Dellorto crowns the Shovel again.

But the best news was that the cool Dellorto was even better than the boring, mainstream CV !!

Turquoise -> CV vs Red -> Dellorto

Carb tuning

When all the hardware job was done with the Dellorto carb the tuning begun.
After some tips from a English company that sold me parts I was on the road.
I realized quite fast that I needed some help with the basic tuning but the sad part that none had any experience with it. So the only thing was to use books to become familiar with the Dellorto.

This book and Matt at dellorto.co.uk was a enormous help in this adventure

But after hours of reading books something was still missing, so the hunt for a Lambda/AFR meter begun. Quite soon I found a decent one to a great price. 

A Lambda sensor bung was welded in the rear pipe and the gauge was mounted in the fairing instead of the broken clock.

The lambdameter hooked up in the fairing.

And a lambda sensor in the rear pipe

New carb

One day I saw a picture of a Dellorto DHLA two throat carb mounted on a long intake and I was hooked !!
I soon found an old intake on eBay and when I got it home I started by de-chrome the dodgy chrome and then did some hard time by the polish wheel and eventually it got a new shiny life.

The carb hunt was up next, after a while I found one in a really bad shape that i got for a bargain.
It didn’t matter because I was to rebuild it completely so I went for it.
First stripped it down completely and then some glass blaster before it got all shiny inside bits and fresh gaskets.
Really expensive in the end but when I saw it mounted on the FLT together with the awesome shiny intake and the huge K&N filter with velocity stacks hidden under it was worth every penny I can guarantee.

The new carb adventure started with this mess...

...and ended like this, maybe the most awesome Harley carb setup in the history

And to get all hardware together became the easy part when looking back at this project.

Next step was o get it dialed in properly, not the easiest task I discovered.

The fourth winter (10/11)

The fourth winter was supposed to be a middle year with just some minor tweaks but it didn’t last very long so the first spring run was made in the middle of the summer.

This year these things got my attention
