I open a question to you gear heads. The Hayabusa is 1300 cc with four cylinders, the Burgman is 650 cc and two cylinders, both are Suzuki motors. Has anyone checked to see if the heads or pistons or cams or any other parts from the Hayabusa motor will fit the Burgman? The Hayabusa has many performance parts available and that motor makes serious power. Is it possible to put any of those parts on the Burgman motor for extra power? I have looked everywhere and no one seems to make performance parts for the Burgman 650. I already have the high flow air filter and performance exhaust but another 10-20 horse power would sure be nice as I ride with Harley's and they can still take me on a roll on (but not by much). I don't even see an overbore kit. I love the Burgman (I got rid of my modified Yamaha V-Max, 150+ hp) after riding it, but a little more power would be nice. I have modified and raced motorcycles all my life and at this time in my life the Burgman 650 is the way to go. I know that most scooter rider are not as performance oriented as motorcycle riders and thus the lack of performance parts for the Burgman but I'm open to ideas guys.
