Has any one put a 840 kit on there Dragon?

Has anyone out there put a 840 or 860 kit on there 08 Dragon 800?
If so have you had any bad luck with it or all good.

I have heard so many bad things about the 800 motor that i am hoping that I can fix the problem before it starts to be a problem

Haven't got a big bore, I did carls cylinder and case porting, head cut and ecu tune, SLP twins and wow there is a lot to be gained on the stock cylinders. Reports from others are ported twin piper is slightly stronger than 860 single and 860 twin piper runs considerably stronger again. Nice thing about 860 is that although expensive you have aftermarket cylinders and pistons that hold up better than stock. Go for it, the boys at carls have the goods.
