Don't know weight but you will want to check the power curve -- these bike engines make gobs of HP but almost no torque at low/mid RPM. Afraid you would be cavitating unless you are planning on using featherable prop. Most Asian bikes are equipped w/ wet sump oiling systems, something to consider. Porsche makes a sweet aviation engine if you insist on something exotic.
PS. -- I'm a car guy and know NOTHING about this subject.

The weight of that engine probably isn't specified any where. Some would have to take it out and weigh it.
It might make a good aircraft engine but I'm wondering about economy and you would have to have some kind of reduction gear box between the engine an propeller. You would have to reduce the RPM's by about half to use a normal propeller. These engines can rev to 10,000 RPM or more. You would also have to make major modifications to the crank case to eliminate the clutch and transmissionto reduce weight. Sounds like quite an expensive project. If money's no object, go for it.

It isn't what you want, unless your going to cut off transmission and gear down to 2,000 rpm for prop?
do you actually know anything about aircraft engines???
You want high torque at low rpm with FAA approval plus a low vibration level.
How much power do you need? If its in the 150hp range the Honda with dual balancers is better (or Suzuki) its not just the power its the vibration levels, you have to make everything heavier to damp them out. Have you looked at Subaru flat fours? with turbo they will provide more than you need without excessive rpm (and a damn sight more reliable than a Lycoming) Maybe a Mazda rotary engine, light and pretty much vibration free (plus its already been approved) you just need to know TBO at given power output

If you are serious, you have to think about performance at altitude. Go to this page if you want low weight with good performance.
