All the left over bits are free to a good home.

well, it can be done....and there is a pic on here somewhere.... I saw the bike at the annual gathering at Baskerville Hall a few years back.

SteveH may know what/where/who

What bits will you have left over?

(i think there are issues with the chain line..and squeezing in the radiator)

I've not done this myself but have spoken to a Pascal from the Dutch MonoConnection that has successfully done this conversion.
My understanding is
- The engine mounts line up but you may need to bush the upper rear one.
- The electrics are completely different, the easiest approach would probabaly be an SZR/Muz Skorpion/XTZ harness, complete with CDI, reg/rec etc.
- Carbs are further apart so you will need SZR/XTZ items and wont fit airbox.
- The SRX oil tank will be in the way of the starter motor, SRX600 monoshock or SZR oil tank should work, (Pascal modified his)
- Chain alignment, the sprocket extends 10mm further out than the SRX, this cause wheel alignment and issues and the chain runs very close to the frame, apparently the XT600 has a dished front sprocket which can be reversed,  the bolts holding the seal retainer will also need machining
- the right hand downtube will need to be modified to clear the water pump
- mechanical rev counter drive will need to be fitted to head if you want to keep the SRX clocks.
- Exhaust - not sure I think Pascal modified an SRX exhaust to fit.
- Need to find space for a radiator/thermostat

I was thinking of doing a similar hybrid but Im not so sure now....I was going to use an XT660 engine or I suppose that an MT-03 engine(if one can be found but probably at a price). Im still open to options but I think I may get a frame off beeman and "go with the flow". I learnt a lot of lessons putting the electric start 400 engine into the twin shock frame and for me that was one hell of a hill to climb. I may take the easy route, but it depends on what I can scrounge or otherwise procure.

Hands are itching now lads and lassies,

Any surplus parts glady accepted Eveder.

Ian :)

srx exhaust will not fit as the exhaust on the szr comes out at an angle as opposed to straight on an srx. i only know this cos i bought an szr exhaust for a srx project and thay wouldnt fir my srx lump. on the plus side standard szr headers should be ideal for waht you need and sorry i dont have them any more.

It can be done although I never understood the reason why one would when you can pick up a Skorpion for so little these days?

I like minimal stuff... 2 wheels, 1 or 2 cylinders etc, preferably air cooled & naked  8) ;D

Yet to see a really tidy water into air chassis job. Always bits sticking out.. :'( :(
