Here's how you not just keep up with the
new model bikes, but blow them into the weeds.
All you need to do is fit a big bore piston kit, 1mm oversize valves,
some good cams, and port and flow the cylinder. We also put Falicon rods
in this one because it gets flogged mercilessly ridden
quite hard.
UPDATE: this engine has now done over 50,000km and still has
175 hp
Enjoy the pictures and "feel the difference"
