GS 1000 ST weight saving program

Like what your doing, I know you can put Bandit 600 wheels in a GS1000 use the GS500 twin sprocket carrer with the B6 rear wheel and it all lines up nicely and is less waight than the standerd wheels. As its been posted the GSX1100/750ET (gs 16v head for the US) dose a strat swop for the standerd GS1000 swing arm and is lighter and twin shock. Also I put a GS850 Gen and rotor on my GS1000 there smaller and lighter and has no probs with charging the standerd GS1000 batt ;) or you can go down to a 10A batt smaller and lighter batt, use a 10A batt on my day to day GS1000 with no probs.:)

Weight

Hiya John
Those were only ideas. It is hard to keep track of all that you got and which direction you are going with each.
I wish I could afford the BST Carbon wheels as well but it looks like a NO.
I would weigh my '07 GSXR1K wheels but I only have a bathroom scale and not particularly accurate. Would it work to get a guestimate? they have the stock brake rotors still attached and cush too.

I've done a similar conversion on my 1100 Kat with GSXR 2nd gen components except the fork tubes from a Bandit 1200 for ground clearance.
It's a pity but I did not weigh the components before assembling the bike:o
I really like your idea of putting a GS 850 gen and rotor on the bike;)
The Kats came with special gens to reduce weight but also I suppose to reduce the crank inertia.
A double good idea!
Thanks

Weighty 2

Weighty 2

Hi again. I would recommend the smaller altanator. I have a GS750/850 with the starter clutches too. But the better bet would be to try and graft an early 2000's GSXR rotor and some kind of Sprague starter clutch. The rotors use rare earth magnets and weigh half what the old GS ones do. And the Sprague starter clutch gives less trouble.
And a side note, stay away from steel belted radial tires as well. They way much more than the Aramid and Kevlar units.
Laters all.

I will look into the GSXR alternator opportunity:)
There is a guy here in France aptly named "Madmax" who has entered the complete GSXR 1100 in a 3D CAD system.
Well worth a look here: http://grabcad.com/library/1100-gsxr-project
I will ask him if he has detailed the GSXR 1000 rotor yet?
In the meantime I got my GS(X) 1100 swingarm back from coating and the weight is 3087 gr versus 4227 gr for the OEM steel version ( both without bearings and spacer)
A whopping 1140 gr!
Total weight saving so far 12.7 kg + 1.14= 13.84 kg

The SolidWorks program is really fun and he must has spent months drawing everything up. He did a really good job too as you cannot tell for the most part that it is a drawing and not the actual bike.
The GSXR rotors I am speaking about go on the end of the crank much like the GS units. The early ones have the same taper as well. I was looking into converting my GS11 engine as well but no one would appreciate and after all this, I will sell it anyway. I have an 1127 GSXR engine, Busa 2x
ZG14engines and will acquire an early GSXR1000 engine as well. So, no need to dwell on the old GS engine. But the hard part will be getting the Sprague starter clutch welded to the alt rotor. And modding the cover as the rotor is shorter than the GS. More ground clearance is always welcome.

Greg,
I looked at some of the pictures I took when I had to fix a loose rotor on my GS 1000 skunk and you are right, it could be a nightmare to adapt the GSXR 1000 rotor to the GS 1000 starter clutch:eek:
Maybe that with a rotor in hand an easy solution would pop up requiring no welding as on the GS the starter clutch is bolted on the rotor?

Getting rid of the infamous regulator would be a big bonus:cool:

John, I will try to get some pics taken today for your perusal. I would try to use a Sprague GSXR starter clutch instead of the GS. It is not only more durable, but lighter. I am thinking that the 2006+ GSXR600/750 had a starter clutch on it that bolted on. There are a few complications though.
Eliminating the stock reg./rec. would be perfect but alas, trying the air/oil cooled GSXR alt with a belt being the only way, the next best solution is PosPlayer's solution. Only I have not tried it yet.

Just had a look at Shorai batterys, (lithium-iron) they say there 80% lighter than a stander battery battery ref LFX14L5 B5R cost ?119.96 +vat in the UK

Looks good!
I saw a GS 850 rotor for sale today, do you confirm it's a simple plug and play?
Today I saved more weight with a 530 chain;)
630 chain 2863 gr , 530 chain 2210 gr or another 653 gr!
Total gain so far: 13.84+0.65= 14.49 kg

Yes just plug and play, I'm running a GS850 rotor and geny (you need both) on my GS1000g and the GS1000 shafty and chain are interchainable.

So make shore you get the rotor and the geny as there smaller then the GS1000 one, then just bolt them in plug the wires in and your away :)
PS running a GS1000g geny and rotor on my chain drive GS1000 :lol:
 
Wouldn't you also need the 850 cover? As the stator is smaller along with the bolt pattern. Starter clutch may be the same as the GS1000?

I got my rear wheel in place today with another weight saving from the sprocket carrier;)
Before 1722 gr, now 1358 gr or 364 gr saving.
Total so far: 14.49+0.36= 14.85 kg.
Here's a picture as of today with the left silencer missing in order to see the beautifull GSX 1100 swingarm powdercoated in satin black:cool:

I believe that there is about 5 kg's to be gained from swapping the steel engine and other bolts for aluminium and titanium ones. Just make sure that you use titanium where the strength is required. They are a lot cheaper than they used to be and easily available.

Sounds like a good idea:)
I wonder if anyone provides a kit with a complete set for the GS 1000?
 
Love this thing. Of course, you'll shed more g's binning the center stand ;)
Where did you come by the 4/2 exhaust system? (... custom?) Any plans on rear shocks?

More ways still

More ways still

Yup, every gram counts. The small battery will be significant and the Titanium bolts will be small. How about small, plastic blinkers? Fiberglass body parts instead of the steel? What about changing the exhaust for one with one aluminum muffler? Or carbon fiber? I have one that is only four pounds. Maybe 2 Kilos? Centerstand? Titanium axles front and back? Pivot bolt? Still want to keep the twin shocks? Any chance on using the Air/Oil cooled GSXR engine instead? There is some weight to be saved there.
Okay, laters
