I fitted the 904cc big bore kit - replaced the air box with pod filters - fitted the 40mm Keihins and now get 70hp & 68Ft/Lbs of torque. Pulls like a schoolboy.
The whole journey including mech work was about Au $6000.
The 1200 kit requires stroking the crank which requires welding & grinding. the special mob that do it wont garantee that the crank wont crack 'A' during welding, or 'B' during use
