Coolant Sensor locaton

I'm squirting an oil cooled Suzuki GSXR 750 m, I've got most of my stuff ready for the install, but a suitable location for the CTS is eluding me. Any ideas? I don't want to stick it in the side of the engine if I can help it and the bike is unfaired and it would be susceptible to damage.
Cheers

here's a thought: there are a couple of parts producers out there who make Oil Temperature Sensor adapted Oil Pan Drain Plugs.

just a thought.

I have had my coolant sensor in the engine oil (on various locations and fittings) during previous seasons, and always found the behaviour and info provided to the ecu was hard to dial the various warm up settings and such (with a standard GM type closed end sensor).
This year I have the same sensor threaded into a small aluminum block that is fastened to cylinder fins on the trailing side of my right hand jug. With a couple of revisions on the 3 point calibration of the sensor (as cylinder temp gets much higher, but quicker) and tweaking of the various start up / warm up tables, I have found very good operation all around.

EWFlyer,
Modding the sump plug and buying an adaptor is a good idea...it's not quite what I did on my old car sump

I didn't bother making an adaptor, I just did a bit of research and found a M16 x 1,5mm sensor, and just got the right type of connector on the end, that was cheap & easy to crimp (2 way Junior Timer). Most component suppliers have descriptive parts specifications.
R100RT,
Same idea as yours, this guy fits an aluminium tube to an rocker spring cover, which is threaded to take a CLT sensor. It works well too, and gives a closer approximation to the cylinder temperature, than an oil based sensor that's cooled by air passing over a sump, like I did!

So my recommendation
davecara would be look for a suitable location with a screwed in plug, and establish the thread size, and go trawling for a sensor. An IAT will work the same BTW.
