At the time, todd henning was managing to get out of the CB450 twin (pushed out to 500 cc) something like 65 hp, so i guess that a 1000cc with 130hp is not out of the question.
but indeed, he had to re-angle all the valve guides and essentially redo the whole combustion chamber to get the bigger valves in. a lot of work in a twin, X2 work in a four!
but it is good to see the two graphs, it really proves all the theories about big bore effect, the torqu is up to 7000 but goes down faster from there.
BTW, its the first time I notice your leading axle fork! what is from? an 80's suzuki?

fork is from a ducati. it is a 38mm marzocchi, bougth from ebay and came with ultraligthweigth upper and lower magnesium forkclamps. worked fine, but had some chattering in the front end. a friend of mine did some improvements (cartrigde system?) to the internals and now everything is perfect.
a few days ago I received a 43mm cbr600f fork from ebay, belgium (for my next project). according to sellers description "everything 100% ok and straight".
both fork tubes bent, one heavily, both fork clamps bent. maybe in belgium there are rulers working very different from mine. oh no, its why these days we all have to buy a lot of expensive x-mas gifts nobody needs
