Stock vs. GSXR bare front rims:
These were a little harder to weigh. My new scale will not weigh objects under 10 lbs., it seems. So I weighed them both with a tire, and subtracted the known weight of the tire.
Results:
ZX-14 bare rim: 11.6 lbs.
GSXR bare rim: 9.0 lbs.
This is more of a difference than I thought! I verified my findings with my old scale. It showed 9.0 for the GSXR and 11.5 for the ZX-14 (the scale only reads in .5 lb increments).

Stock vs. GSXR rear rims with cush drive and sprocket carriers:
ZX-14: 19.5 lbs.
GSXR: 15.4 lbs.
I did not include wheel spacers, brake disks, or sprockets. These items will vary with each application.

I picked up a scale to weigh small parts:
For the really small stuff, it can read in grams. I will be using pounds and ounces for these:
Front:
ZX-14 Stock 2 lbs. 11.5 oz.
GSXR Stock 3 lbs. 5.2 oz.
GSXR Galfer 2 lbs. 15.1 oz.
All of the fronts are 310mm. Surprisingly, the stock 14 front rotor is lighter than the Galfer Wave for the GSXR.
Rear:
ZX-14 Stock 2 lbs. 14.3 oz.
GSXR Stock 1 lb. 12.1 oz.
GSXR Galfer 1 lb. 4.1 oz.
The ZX-14 rear rotor is 250mm, while the GSXR uses a 220mm part.
None of these weight differences are going to make even a 1 mph difference. But it is nice to know precisely how the bike is set up, and where the weight is coming from or going to. Every little bit can help.

I need one of them scales too,
Where did you get it?
I knew the rear sproket was considerably heavier, but am surprised the galfer frt isn't the heaviest actually.
The runout on some of our strips are quite short for the big mph I hope to run, so that was one area where function was more important to me than light weight.
Thanks for sharing Shane!

I actually got it from a local Target department store. It is a food scale. Should be easy to find, although it was pricey at $50.

People often ask if it is worth it to change to an aluminum rear sprocket. Well, it all depends on what your goal is. There is no question that steel will last a lot longer with similar care.
Here I have a stock 43T GSXR sprocket, and a 43T aluminum Renthal:
Rear Sprocket Weight:
Stock GSXR 43T 1 lb. 12.1 oz.
Renthal 43T 11.2 oz.
Over one pound difference. The Renthal is a very light part. I am not sure how it will hold up in a very high hp application. We have had no problems with a season of dragracing on Racheal's 1000. I have a Vortex sprocket here that is much more stout; but it is a 45T. That wouldn't make for a fair weight comparison.

My dirtbike experience with Renthal, is they make the entire chainwheel, including the teeth much more narrow, and they wear out extremely fast.
PBI and sprocket specialists were my favorite dirtbike aluminum sprokets.
Thats with a CR500 worked to the nutz , on c-16 making 70rwhp and weighing 225 lbs...
close to the same HP/ LBS of literbikes!
The new Renthal with the aluminum center and steel ring looks like a good design though, form a wear perspective, not sure how strong they are where the metals join.

Nice work with the new scale!
Would you mind weighing the stock zx14 41T sprocket too?
It's heavier when held in hand than the stock gsx-r unit, if I remember right.
Someone on zx14ninja.com had weighed the front Galfer Wave zx14 rotors
and they were roughly o.5 lbs. heavier than the stockers each! Kawi did a good job
with those... and I never had a good reason to buy the Galfers... 1 lbs. more on the front
wheel assembly is not what I wanted to do.
Not sure if you already use titanium rotor bolts or not- the 10 Ti front bolts are around 0.3 lbs. lighter than the 10 oem bolts. The 5 sprocket bolts and the 5 rear rotor bolts in titanium are also around 0.3 lbs. lighter than oem, I got some good deals on eBay and replaced
all those bolts on my bike with the wheels swap.
Always a pleasure to follow this thread!
Thanks!

Stock ZX-14 Sprocket: 2 lbs. 0.1 oz. (The .1 oz. is probably the grease on the sprocket  )
The front rotor bolts have to be changed in this application. The GSXR bolts have too short of a shoulder for the shimming that is required. So far, I have only found class 12.9 shoulder bolts from McMaster Carr that will work properly:
These bolts are very strong, but also heavy. Also, the heads on them are tall which creates a clearance issue on one of the fork legs. I would like to find some lower profile bolts with a long shoulder, but I've looked around and can't find any.

Shane, just to follow up on the kickstand binding. What I found was a heavy amount of chain wax binding the kickstand switch, removed the switch cleaned up reinstalled no problems and just a side note it is some sort of lock nut on the inside of the stand with a metal locking device its different than a nylon locknut but does the same purpose i have never seen one like it so it was interesting looking once all cleaned up heres a pic.

I wanted say, its been great reading all of this.
When I was begining to get bummed out and losing momentum on my project, this thread inspired me to get the house stuff done as fast as possible and get back to it.
Thanks for taking the time, and thanks for the inspiration...
even when I couldn't work on it, as the garage was in shamlbes and the bike was in the garage, it kept my mind in the loop and I continued planning, reading, learning and building the inventory.
now I can't get my head out of my project ... Thanks 
and my wife would like to thank you too... NOT! 
LOL

Thanks man. I've lost momentum more than once myself. I'm glad I have all of the pictures, that kind of kept me going. Plus, I would never keep these kind of notes at home.
I think it's time to add a table of contents... 17 pages! Bawls suggested it a few pages ago, but I never got to it.

My new custom axle arrived from McIntosh today. It is a fabulous piece. Here it is compared to the stock GSXR piece (hint: the McIntosh part is the shiny and stout one):
Here you can see that the new axle is not tapered down on the threaded end. The GSXR piece is much smaller and weaker:
I knew the new axle would weigh more:
GSXR 1 lb. 2.4 oz.
McIntosh 2 lb. 1.8 oz.
Although I hate to add weight, it is worth it in this case. I ordered this axle Friday...Terry made it the same day and it went out that afternoon. Excellent service.

Yes Terry's stuff isn't light. but it won't break either.
And everything is made perfect.
MacIntosh is an artist for sure.
The axle blocks, axles and nuts are machined billet aluminum!

Removed the OEM battery for weight comparison to the Odyssey 310:
OEM Battery 11.1 lbs.
Odyssey 310 Battery 6 lbs. 0.4 oz.
I was considering the Speedcell battery, but I'm going to hold off until when/if they start shipping in numbers.

My GSXR rear caliper came today. The caliper is a Tociko. The oem ZX4 caliper is a Nissin. I am not sure how the master cylinders stack up (spec-wise), but I'll find out later. Anyway, here are the two parts mounted in their carriers:
No significant weight savings will be found here. One ounce total, at most.
Here are some pictures showing the nice fit with the billet hanger:
And a couple of shots showing the direction this is all headed in:
My front rotor spacers are supposed to be completed this week. If so, I should be able to finally fit the front wheel.

I will probably end up running the caliper above the axle, due to my wheelbase and nitrous bottle. Like this:
It shouldn't be a problem either way...it all depends on your wheelbase and clearance needs.

Doesn't seem like it would ride too well without a front wheel on the pavement?
I guess you could fit some old style sliders with some custom triples. But even Kosman drag racing forks are inverted.

Now that is trick!
I really like that piece!
what yr gsxr caliper? the 2006 caliper I had was identical to the zx14 caliper.
I also like the fact that your arm is so light.
I guarantee my mcintosh arm is AT LEAST 2.5 x's the weight of the stocker.
is the wheel all centered proper now?
I just have an outside spacer set to take up the space for now, but was going to have it welded, or a new custom piece machined... too many loose parts on the rear axle is a PITA as mine is currently.

2007-2008 GSXR 1000. I got the caliper (mint) for under $50 including shipping. Off of Ebay.
Due to the way the hanger works, I will end up shimming the rear rotor out. Otherwise the hanger bracket will not catch in the arm. There are a thousand ways to do it, of course....you could modify the hanger to extend the tab.
