Why did you shorten the wheel base?

Two reasons:
1) There is no traction at an LSR venue, and the long wheelbase is a problem in the lower gears. If this were a dedicated LSR bike I would shorten it even more.
2) The 40T sprocket would have kicked the wheelbase out to the very end, or beyond the range of adjustability of the arm. A 5 tooth difference affects wheelbase significantly.
I will be putting the bike back to 64.25" when I return from Maine.

Thanks Todd. I'll definitely be taking a back seat to your nitrous bike in Maine. 1.5 miles begs for hp, and I'm afraid I don't have a whole lot.
HP vs. aeros...it's that simple when given the room to run.

I knew about the sprocket /chain and moving the the wheel base been, there
done that. And I saw your master link with the glue on it :-) I still have not mounted your old Spencer Cycle swing arm ext. yet. Your stock 14 wheels are polished now for a back up.

it and see what A/F is when I am in the Mountains. It is running rich in the Mountains.

I installed the Factory Pro "race" stacks this afternoon. This has been covered by someone else in a thread awhile back, so I am just going to offer a few tips/suggestions.
First, why install stacks? What do they do? In a nutshell, they optimize the length of the intake tract for a certain rpm range. The don't really add much power, they just move it around. Compared to a stock, street driven bike, I operate in a higher rpm band. By fitting shorter velocity stacks I hope to get better performance in the upper rpm range.
In order to install them you will need to remove some body panels, the fuel tank, the inspection plates, and of course the old stacks.
Old vs. New:

You can see the new parts are quite a bit shorter. There are other areas these aftermarket pieces can probably be improved, but I simply don't have the time nor tools to work with them right now. Maybe I will mess with them some more this winter.

I lubricated each stack slightly with WD40 so that they would slide onto the frame easily. I pressed flat down on each stack and they inserted with an audible "pop". It is important to make sure that they are sealed to the airbox/frame.

When you install the clamps on the rubber boots, I suggest you stagger them like so:

This way you can tighten the inner clamps without having to remove the front ones.
Installed:

Total install time was 40 minutes, including removing the body panels and tank, but not including re-assembling the bike. I feel confident that someone familiar with the ZX-14 can do this job, start to finish, in about 1 hour.
I am hoping to get the bike on the dyno before heading to Maine. We'll see how it goes.

I got the bike on the dyno today:

Setup:
No Air Filter
Factory Pro Short Velocity Stacks
Brock exhaust with Area P Carbon Megaphone (2.25" Baffle)
Kleen Air Removed
MR9 Fuel (no more than 10% pump fuel)
Honda 10w40 Conventional Oil
Brock 200 Maxton Map
It was hot and humid today, so combined with the slightly diluted MR9, I expected the bike to run a little rich. It did. I am happy with that since I am taking it to Loring which has cool temps and elevation very near sea level.
Here is a comparison to what the bike ran a couple of months back, on pump fuel:

The bike was getting hot on the dyno; I believe that 183 is actually the lowest # it pulled today. I was not surprised to see this, since I know the bike loses mph at the track when it gets hot. But I wanted to compare the the torque curves with the new stacks. You can definitely see the shift in the curve. It is what I wanted for LSR, but it may affect me at the dragstrip.
Here is the best pull, which was made in 5th gear, after the bike had time to cool:

186 hp. Pretty good considering it was running rich. After the Loring event I will take some time to have it tuned properly. But I like the way things look for now. The map should be plenty safe for the 1.5 mile runs.

I would say that if you were initially hesistant to do it yourself, you should allow a couple of hours for the job. I have had my bike apart many times, so it went quickly and smoothly for me.

How much of that gain was MR9 ? or the stacks ?

Since it is not fully tuned, I am not really concerned at this point. There are too many variables to figure it. Since I don't know what the a/f was on pump, it can never be an apples to apples comparison. Later, when I have time, I might dyno the bike again on pump with the street map, as before, but with the stacks. The stacks did do what I wanted by shifting the power, as can be seen by the shape of the torque curves.
My best guess is that most of that peak power is from the fuel. Stacks are a very fine tuning sort of thing, and I wouldn't expect a whole lot of hp from them.

On a Super Flow Eddy Current dyno we did not see a HP gain in 5th fear over 6th?
Hope you had a Good Birthday.

I don't believe any significant gain/loss would be seen. Overall ratios weren't too far off because I have changed the gearing to a taller 5th. I couldn't dyno it in 6th, as before, because the gearing exceeds the capability of the dyno.
The dyno is just a measuring tool, and I am comfortable with what I am seeing. Particularly as related to the shape of the powerband. The ultimate test is at the track, and there is still plenty of tuning to be done.

Thanks Zack. I hope that with some more seat time I can come closer to your #'s at Maxton. I just don't know if I can get out of the wind enough! I've got another 5.5 mph to go...and that is a looooong ways!

I like your optimism.
One more dyno chart. I examined my runs with Winpep 7. These two runs are done with a very similar gear ratio. Based on what I am seeing, the gear ratio does affect the dyno numbers to some degree.

Again, just to illustrate the shift in the torque band from the stacks...and the difference in power at approximately 200 mph with my current gearing. Keep in mind the switch to MR9 and the map change as well. As stated, the MR9 is likely responsible for most of the hp increase.

Shane - Tell me if you see anything at the track on those stacks - I have the street stacks in mine and just ordered the race stacks....... I am going to have the bike tuned again and then I will need to start the aqusition thing back up and playing with it.... I also just got some adjustable links and I will try to take the rear as low as it will go with the clearance on the tiger tail.... in hopes of getting a little bit more in the 330 times.

Just a quick update from Loring. One licensing pass today, and one full pass into a head/crosswind.
My licensing pass was made with a target of 175 mph. Well, based on my gearing calc and just reading the tach, I was pretty close:

Here is the result of the full pass:

Check out the handwritten slip! This track is amazing; I am so glad that we made the trip. I also think if the winds improve tomorrow, I may have a shot at 200 mph.
But the best news of the day was with Racheal. She made one full pass into the wind at 204 mph. Since this is a first event, she was able to grab the record. Well, that makes her the first woman into the Loring 200 MPH Club. Pretty cool, huh?
We'll both be looking to better our #'s in the morning, and hopefully I can get some pictures of the track and things.
