We'll want the fuel shutoff to be able to be operated without removing your hands from the bars -- but only if you're running nitromethane.  Either electric or cable (thumb-actuated) is acceptable.  You can get the thumb type from Pingel.
Hi Slim; I checked Pingel's website , I may very well be a bit dim, but I can't find'em.
Could you possibly point me in the right direction.

Thanks.

Today I worked on the air intake box. I fabricated the 9 inch round backplate...for the third time :x. I cut the first two plates from some 18ga stainless steel I had and ended up with 2 oil can bottoms. You could pop them back and forth just like an old oil can. I got out a bucket of ice water and the torch and tried to shrink the metal, but no joy. Sheet metal work isn't my strong point, so I finally cut a new one out of some 16ga mild steel and it remained flat. Now I have to paint it...dang! The intake tubing is 2.5 inch aluminum tubing and I will have a bellmouth made for the front.
Now I just have to decide how deep I want the box and make a cover.

The air box cover has been meticulously fabricated and finished using proven TLAR* engineering...

Things have finally gotten back to normal around here and it's been too hot to work outside, so I'm able to work on the bike again. The airbox show on the previous pictures was too high. I had to put my arm around the outside of the box to reach the controls.
I decided to rotate the box down 180 degrees and run the intake in through the cover instead of the back. I will weld the opening in the back closed...

I installed the intake tube in the cover with the outlet pointed away from the TB intake...

This ended up being a much simpler installation than the previous one...

This setup will be used only while I get a feel for the adjustments needed on the fuel injection system. Once I get the hang of that, I will install some different pistons and fit the turbo to the bike.

I'm not sure how well this throttle cable routing will work. We will see when the bike hits the floor.

Is that an EGT sensor in the top of the rear pipe? The bike is looking great.

Thanks Fred, that's the factory (single wire)oxygen sensor in the stock location for the Buell fuel injection. I have another self heating O2 sensor at the Y in the pipes for the data logger.

Did a little work to relocate the throttle assy guide hole on the clip-on and re-aligned the throttle cables in a much better direction...

I decided not to use the Charlie Toy LSR fairing on this bike. That fairing  was very wide for my build and I didn't want to narrow it since I have a GSXR frame that I'm going to use it on...

I talked with Kent at Airtech and we decided on an appropriate fairing. The S&S fairing is a much narrower LSR fairing and should present a smaller frontal area for the bike. I picked up the S&S this morning at my local shipping depot. It was as expected, another quality product from Airtech.
