(3) Your system hasn't reached saturation point.

(4) Your "airlock" is likely cavitation.

1, still rubbish. The guard extension is too far away from the rad to make an ounce of difference.
2, saturate heat? You mean overheat. No I don't.
2a, I agree.
3, what are you on about with this "saturation point"? The cooling system reaches a temperature (103C I think on these) that'll trigger the cooling fan to kick in. My system has got hot enough for me to feel the heat blowing onto my legs (the known hot air problem) So I reckon it's got as hot as it can. The fan comes on and the gauge stays at 5 bars. Therefore my system is working as it should. The OP's system does not.
4, rubbish again. You don't get cavitation in a radiator/cooling system. You get an airlock likely in one of the pipes/tubes which prevents the liquid circulating around the whole system. That airlock allows steam to form which then expands and blows coolant past the rad cap. Cavitation = http://en.wikipedia.org/wiki/Cavitation

Well, at least I got you to agree on something...

Turns out that it has a crack in the #2 cylinder sleeve.

I've got to hand it to the dealer that found that. Nice find.

Wow. How the hell did that happen?

I'll bet there was a hairline crack in it from day one and just got progressively worse with each heat cycle.

I've been casually reading this thread and all it's misunderstandings and myths thinking "head gasket", which almost came to light with the find of the warped head. Cracked cylinder? Same difference.

Sometimes the hardest machines to troubleshoot are nearly new ones because your brain wants to say things like headgaskets, cylinders, or any other major component don't fail until you are many miles in.

I think you hit the nail on the head. They couldn't see the crack until the cylinder sleeve was pulled from the engine. The poor tech has been dealing with this bike for a long time now. I think that on a warranty repair he won't get paid until the job is complete. I definitely need to buy him lunch or something.
Although this process has taken a long time, I can't say enough about how it was handled by the guys at RPM Cycle and at Triumph. These guys are top notch and really went above and beyond to keep me riding a Triumph for many years to come.

Sure hope the cylinder gets fixed promptly and permanently. Also hope it's an isolated case.

My overheating problem is gone for sure. Triumph decided that I was spending too much time without my bike so they sent me a 2013!!!!
