Hey there,
Just a few notes>
Squirting a GSXR1100 isn't too difficult. In mine it is in a car, but in a bike there wouldn't be any problem with fitting most of the stuff. The fuel pump would be quite different but its all very tractable.
Here is what I managed:
gsxr600 k1-k2-k3 throttle bodies, respaced in the usual fashion with the only challenge being the central throttle coupling that needs extending. Secondaries removed and holes filled with JB weld.
Air box is standard GSXR1100, but with the rubbers from the GSXR600
Air temperature sensor from GSXR600 and mounted in the airbox before the filter.
Fuel rail needs replacing. I used rossmachining stock and drilled carefully for the injectors and tapped the ends to block them off. Standard injectors (these are supposedly rated at 240cc/min, although I couldn't find a non-forum source for this).
Fuel pump is GSXR600 that I have mounted in the tank (underside with a bit of a sump). No filter between pump and fuel rail (there is none on the bike so why complicate). Pump is self regulating and includes a filter, no return fuel line. All nice and simple.
Water temperature sensor is mounted in the GSXR1100 themostat housing and replaces the fan switch. Intermotor part number 52730.
So that is all the hardware:
Electronics use a standard MS1 board.
Tacho is supplied using a pair of diodes one to each of the negative sides of the coil. A pull-up resistor (1k) is used to ensure a decent trigger. This works nicely.
Sparks are provided by Suzuki standard CDI.
MS Extra code 29y3, and easytherm was used for the non-standard temperature sensors.
LC-1 with Bosch O2 probe.
A few teething problems (flat battery, poor initial fueling, bad earthing on water temp sensor, and an upside-down AE sensor). But MegaTune and MegaLogViewer have been excellent. The autotune functions have given me a great table, and the car (460kg of it), is all a bit quick.
