Mines going good.
There are two other big bore XT's been done right now behind the scenes.
So you ask what's Kev up to.
I am going to repack my Carbon cans this weekend, so a how to report this Saturday.
I am working on a full wiring conversion for my 07 with O2 sensor back to a 06 spec without O2 sensor, I need more control over the fuelling & the 04 to 06 ECU's allows this.
As for the other guys you will have to wait for their response. If you are after some sort of performance package kit, I think it is a long way off. There is no great demand for such a kit as yet.
The facts are since I have shown that a big bore can be done to the XT660, I only know of 1 other person that has actually done the conversion in the world & 2 more on the way.
