I am assuming that a liquid cooled version would retain much of the camhead design, including shim type adjustments. If liquid cooling stretches that adjustment interval to 26k or something in the range of competing bikes then I personally would be much more interested. I still don't like the idea of being at the mercy of being able to get the right shim when I need it. I am guessing that after some time it will probably be the exhaust valves that tend to tighten up a bit, and carrying a couple of likely shims may not be that big of a deal. If the adjustment interval goes up significantly in my mind it would be an okay trade-off.
Liquid cooling on its own won't change anything regarding clearance checks. The valve train is also not the same as the twin cam as it will be pure bucket and shim with no rockers as it is now. This should stretch the checks out although to what is anybodies guess. I would also think that the water Cooling and new valve gear could shave a bit off the width but they might have done other things like increase the stroke to widen it again.
