Any overbore cx650's?

Has anyone ever overbore there cx650? I was wondering if it would be possible to overbore the cylinders to make some more displacement? Maybe a stroker? How many cc's do you think we could get out of these engines?

Hi, I once saw a 650 fitted with a piston/ liner sleeve kit ( possibly made by Wiseco) which took it out to 820cc. Whether this conversion still exsists I coundn't say but I always considered the 650 stretched handling the output it has.  If you were to bore it out yourself the problem is getting pistons with the valve cutouts at 22 degrees to the line of the gudgeon pin (little end)
