OK, what’s available for the engine?
There’s not much in the commercial aftermarket for the engine besides carburetor jet kits, a few Ninja 1000 cams, and a 1039cc kit. Determined owners have come up with ways to bump the Concours engine to 1052cc and 1109cc. One has even swapped for a ZRX1200 engine. Another is turbocharging his Concours. These aren’t kits but I’m sure they’ll answer questions if you‘re interested. They have also revised cam timing gears, added Ninja 1000 carburetors, punched out Concours exhaust canisters, and more. No hard performance numbers but 115 HP wouldn’t be too farfetched.
