This is the Exoticycle I bought compared to the stock zx14 hanger.
Won't have my bike out of storage for another month... there are other
vehicles currently in my garage that are in bits and pieces.
I'll probably use some advice from this thread when the time comes
to put it on the bike. It is very small and light

That is very nice compared to the stock piece! 
My hanger came today:
It is designed for the GSXR, so I will retain the 220mm rear brake of the liter bike. You can see how it mounts in the arm here:
I am sure that I may have to change the orientation or even have a little machine work done in the end.

It's nice to be able to drop the torsion bar on the hanger. I'll have my caliper above the swingarm- like on a liter bike. I think it will look much different, hope I'll like it. On the downside the two bolts that the gsx-r uses to mount the caliper on the hanger are smaller than the ones on the zx14 in diameter... at least they are on the hanger I bought.
A slightly dumb question....
Are there any benefits in aerodynamics in having the caliper above the swingarm?
It seems to me it's better tucked away behind your leg.

That area of the bike is pretty dirty, aero-wise. I doubt you could measure any change in drag...

Thanks. I was very happy with the work that Doug did for me. I'm sure this arm will take whatever I throw at it...

I've been scoping out some Carbon Fiber on Ebay for awhile now. Some of the prices are very good. I decided to take a chance on some ram air covers from Bestem. The ebay pics don't give too good of an idea of what you will get...and the price of $170 is low enough to make me leery. But, I figured I would give them a shot.
Well, I was pleasantly surprised:
I am not going to say they are perfect, but for the cost they are pretty nice. Here is a comparison to the stock piece:
The do not have the tiny locating tab that is at the front, so be aware. They are a little lighter than stock...I would attribute that to the fact that they don't have the insulating pads underneath:
Anyway, I'm going to call these a fashion statement mostly. Fit and finish would seem to be above average for the cost. I can't install them for a few weeks, so I'll learn more then.

Shane I dont really see why you would need those insulating pads they just sit on top of the ram air tubes.

I agree, I am not worried about them at all. In fact, I am happy to lose them. I have removed several other sound damping pieces. No need for my use. I'm sure I will have a few mounting challenges with these parts and the race bodywork, but I'm expecting that.

If those carbon bits are Bestem, they are nice.
I really like my bestem pieces
I like the caliper hanger too.
I had mentioned I wanted to do the same but have not ordered one yet.
If yours is one off spced away from the swingarm as rquired?
I am running an additional spacer between my zx14 arm(mac) and the gsxr wheel to get the caliper offset to match the wheel in the arm.
Curious, cause if they made it custom, I will get one made too.

No, not custom...I don't know what mods it is going to require yet...
I ordered a GSXR caliper today, and I also have a late model axle/nut on the way.

Nissin or Tokico?
The 03-04 gsx-r uses Nissin, but the newer ones use the Tokico.

The stock zx14 caliper is identical to the 06 gsxr 1000 caliper I bought....in every way. Just the hangers are different.
The busa axle ( on the bike) I have in the garage is the same diameter as a gsxr axle, it measures 13.25" long from the outside edge of the flange to the end of the threads on the other end. The flange looks to be about 3/8 thick/deep set into the adjuter blocks...
Mot sure if that helps you Shane.
I am using a stock gsxr hanger for now. I machined the locator tab off it, as it will not match the stock zx14 swingarm, the new axle blocks, or my new arm... it does not have a groove for the tab anyway.
The mac arm comes with a locater bar, and I think I am going to stay with that set up.
I like the clean looks of those billet caliper hangers, and the bar less look, but it appears those tabs limit the adjutability of the axle as they ride in frt or beghind the axle in the arm, and I want to run my 4-8 arm all the way to the front on street, and all the way to the back at the track... in fact I am realizing I should have bought a 10" arm to utilzed the rule book limits for my class here in Canada.
The first issue I had was centering the wheel.
- I had to machine a left side(clutch lever side ) collar to get the wheel centered.
- I used the gsxr hanger and collar , this ensured the caliper was hung in the stock gsxr location.
- After that I machined a right side spacer to take up the space left over between the caliper.
So, the wheel was centered starting from the left, then made sure the caliper was cenetered over the rotor, then machined a collar for the remainder on the right.
The last thing was the sprocket alignment. The gsxr sproket was off center approx 4mm to the right. Coincidentally the stock gsxr sprocket is 4mm wide at the base where it bolts on.
I machined the center out of a stock gsxr sproket and used it to space the driven sproket out the required 4mm.
I have not ran the bike to confirm my final mods, but this should get me close with the sprocket, and I am 99.5% confident the wheel is centered.
I used a laser level to lay out tape, using the fuel tank center bolt behind the steering post as a centerline, and the top shock mount for the rear centerline, and also used a shinko with the center groove as the center of my tire for alignment purposes... marked with white paint marker for visibility.
The zx14 swingarm is offset from front to back, and the distances from the arm to the wheel on each side are not identical, makes finding center a biotch.
I would take the wheel off and get you my measurements for comparison, but the front of bike is hanging off the ceiling right now, I will be picking up my machined gsxr t clamps tomorrow hopefully. I don't want to monkey with the bike dangling from both ends as it is not so stable. Once I get he frt end put back on it and can clamp the frt tire in the baxleychock, I will take the rear wheel off and put up pics with the vernier on the parts.
1-2 days

That's interesting. The wheel bearing sizes for the Busa are listed on the fiche as 32X58X13. That would seem to indicate a 32mm axle instead of the 28mm part of the GSXR. I guess there is something going on with the sleeve/spacer arrangement?
I never bothered to check Racheal's Busa...

A great write up Shane. I check it every day to see what's new.
If i had the money, i'd buy the bike off you when you finished it.
As your using it for track use mainly, have you thought of doing a Road kit set up. Whereby you would unattach the Race Gear and have ready-to-fit Road Gear, as in headlights etc, like a 30minute swap over time frame?
Seems a shame that the only people who will see this excellent bike is at the track.
The weight saving that has been done on the overall bike would be great for the road as well.
BTW, what camera and lighting are you using and how many shots do you actually take to get it 'right' before you post it?
Keep up the good work.
Alan.

I might end up putting a small headlight on the bike, and I am going to use a tailight. I really don't like riding on the street too much anymore. But I might take it out for some small rides. Truth be told, I don't think it will really be too much to look at...you know, form follows function and all of that...
I've used two cameras. This Kodak V1253 has taken about 98% of the pics and all of the video in this thread:
It also does HD widescreen video. It was under $250, if I recall.
Lately I have been using a new camera, this Fuji S2000HD:
It also does HD video, and it was about $225 on sale.
I would say that I use 3 out of 5 pictures that I take. Sometimes I am picky about how I frame them up. I am no photographer though, that's for sure!
I use whatever ambient lighting there is, and flash if needed.

Picked up a new tool for the garage:
A No Mar Tire Changer. I have to swap tires a lot during the race season, and it is getting to the point that this tool will pay for itself before too long. Not only is it expensive to get the tires installed, but it takes a lot of time to pick up and drop them off.
I wanted to get some accurate weights on my 14 and GSXR wheels, and it would end up costing me about $150 in labor after all of the tire swapping. Not to mention hours of time. I was able to remove 3 tires tonight in about an hour...and that was with bad technique. I am sure I will get better as the season goes on.
So, here are the two bare rear wheels. 07 GSXR 1000, and 07 ZX-14:
I also picked up a new bathroom scale that measures to .1 lb. resolution. I know it is not the most accurate scale in the world, but should be close enough for comparisons.
First the 14 wheel:
16.3 lbs, bare.
Next, the GSXR:
12.3 lbs, bare.
So, 4 lbs. difference with no brakes, cush drive, sprocket, or carrier. Not bad. More to come.

I am also changing tires during the offseason. I am attempting to find a pair of tires that will work for LSR and dragracing. I will be using the Michelin Pilot Power front tire in the 120/60/17 size.
Here are some comparison shots between the new Michelin and the stock Bridgestone with about 1200 miles on it. Note sidewall height, and overall height differences:
The stock Bridgestone with 1200 miles weighed in at 8.6 lbs, the new Michelin is 8.3. The big advantage to the 60 series tire is that it lowers the front end close to .5". Some people say it can cause instability, but I have run 180-190 mph with 60 series tires with no problem. Racheal has been 204 mph with hers on the Busa. It is more about overall chassis setup than it is about the tire profile.

Hey Shane i have the same kickstand as you and when I installed it the bolt was looking shorter than when it was in the stock one...the lock nut doesnt reach the threads, and it doesnt snap up and down the stock one i have to bring it all the way up with my foot and vise versa. did you run into that?

This is mine:
I don't think the nut on mine has any nylon, the locking mechanism looks to be metal? I didn't remove it to check (not tonight anyway). I also likely put a little loctite on the nut. I also put some grease in the hinge/contact areas where the pivot bolt is. Be sure that you are not tightening the nut too much; it could cause drag.

Cool,have you been able to weight the rims with rotors, cush hubs and sprokets?
I am about to pull the rear wheel off and email sum stuff to ya tonight or in the AM.

I have a lot of different configurations that I am going to look at. I would like to get a small postal scale so that I can weigh the different rotors and sprockets (stock vs. wave rotors, aluminum vs. steel sprockets,etc)).
