GS 1000 engine in GSXR 1100 first gen frame?

[GregT]

Put it on 17's. Back in the day, I was part of a team here which built an 1100 using the same frame as yours. We put it on Marvic 17's, ran it on methanol. With the late Robert Holden riding it set lap records wherever we ran it in NZ. Admittedly Robert was a specialist on the GSXR1100 - he instructed at a race school in Aussie using them - but they really handle very well on 17's. Much better choice of rubber too.

17" are the better choice but as I have some 18" available, I will try these first.
I can swop later on, if required, with the 17" that are on my Katana 1100.
I'm still undecided if I want to give the bike a period look or not?
For the period look I have some old 4 pot AP Racing ( AP 3369) calipers that were used I believe on some Yamaha TZ racers.
Are they any good?
Here are the bits and pieces for the bike:

[GregT]

The XR's used AP two pots but those 4 pots are a very good caliper...very good indeed.

While I'm waiting for the frame to come back from the welder, I bought a fuel tank.
It wasn't cheap but the condition was very good with no rust whatsoever.
Not surprising considering it came from Greece.

[John Kat]

The frame has been spotwelded last friday ( sorry no pictures) and the guy will finish it by next monday.
I'm trying to get all the bits and pieces together to get it on its wheels before the end of the month...
I need to mock up the seat and the tank together and then the exhaust pipe before final assembly.
Here's the seat I'm contemplating to buy: http://www.poly26.com/produits/photo...29abmedium.jpg

As I'm still waiting for my frame to get back from the welding shop, I spent some time figuring out the electric wiring of the bike.
Has anyone heard of Motogadget?
It's a german company that builds all sorts of electronic devices for bikes and one of these devices is an electronic control box that allows a very simple wiring of all the controls needed on a bike.
It's of course all solid-state and it's works with neat handlebar switches that can serve multiple functions.
I'm quite tempted to use their m-Unit allthough it's not cheap at 259 Euros here in France.
Any experience out there?

It is expensive; I offer a cheaper alternative. Solid State Power Box and it is designed to fit in the same location as your existing fuse box which at about "4x2.3" the M-unit will not. See links in my signature.

They have improved the unit (V2) to a lower standby current 0.3 mA/ The SSPB is 2.0 mA for comparison the SH-775 is about 2.5mAmp as well. The Compufire is zero or thereabouts.

Reading the literature they have chosen to complicate the basic design by adding a lot of features that you can get from China for less than the cost of parts.

Tail light modulators are $5 an alarm is $11 on Ebay shipped from China.

My own thinking after contemplating the same was it is a lose lose proposition (more stuff in the box the more likely something will fail and nobody will buy it as it is too over the top). If he want absolute minimum weight for a street going bike and you want to get there by reducing wires then this is the way to go. Ultimately a fly by wire system CANBUS system will be smaller, but now you are really getting into the manufactures domain.

Much of my perspective was looking at this a product to develop. I even did a little market survey of an integrated system for light control that complimented the SSPB. Basically not much interest. I have never pursued MotoViz as there are too many cheap alternatives.

[John Kat]

Jim, to be honest, I hadn't looked closely at your SSPB device.
My goal for this bike is to get rid of the OEM wiring loom, not to have flashing headlights and so on.
The neat part on the Motogadget box is that by simply temporarily earthing one of the inputs you can switch circuits on or off.
I believe your SSPB needs continuous input earthing to control a circuit?
They also have the possibility of commanding the turn signals in the same way.
They can apparently multiplex the control signals through only one wire by adding what they call the m-button?

If I only wanted to upgrade one of my GS bikes, I would definitely go with your SSPB ( and I might still do so ) but for a bottom up build the m-Box seems the good choice ?

[John Kat]

I finally got my frame back from the welder.
At least he did a good job.
The bottom rear engine mounts were extended but I still have to drill the hole in the right place plus some finishing touches.
Here's what it looks like:

I like your project, but I hope you move quickly on it.
Yoshi would knock a project like this off in 7 days, and nights!
I lose interest with 2-3 year projects, can't take those builders serious.

So I should confess, I'm considering a much easier swap of just a GSXR 1127 block into my GSX750F.
The engine seller keeps sending me teaser emails…mercy mercy mercy.

I can't agree more: it's long winded but I suppose life is a long wait between the parts you need for the project and the work you need to outsource...
When and if, I'll be done with this project, I'll put a GSXR 1127 block in my GS 1000 frame maybe like this one : http://www.custom-wolf.de/english/ha...s/mocca-racer/
I'll follow your thread on your build and see how long it takes

Are you aware that you could swap a 1052 crank (earlier gsxr1100) w/pstons and cylinder block, trans assy into your 750 cases? 1127 will fit too but you have to clearance the cases slightly for crank clearance. Stock 750 head works with either.

Wow! This is good info! Anymore info on this?

[John Kat]

Good news: I got the bike on it's wheels today
It's basically GSXR 1100 86 87 with the fork from a GSXR 1100 89.
Still a lot of work to be done and money to be spent but it's a big step forward.
I also measured the weight of the frame alone: 17 kg.
Could anyone give me the weight of a bare GS 1000 frame?







And for those who think it's a bicycle

Very interesting! I wondered if something like that could be done. It makes sense for Suzuki and all manufacturers to design a base modular engine that could be easily modified to other sizes for their different bikes.
I remember all the configurations that could be done with the Chevrolet small block V8
