Now with the 2006 season closed, it was time to act on our existing plans for 2007. It was going to be a busy winter…
The main activity would be to significantly rework the engine to get to as close to 95 HP as possible. The engine has been removed and is currently being breathed on by a highly capable BSB engine tuner. Based on his initial analysis of the engine we expect to:
¨ Gain 20-30 RWHP
¨ Dramatically reduce reciprocating mass
¨ Raise the rev ceiling to 12,000 RPM
¨ Reduce the overall weight of the engine by 10 kg
Of course, this will also require a completely new exhaust system. We will publish the power and torque curves as soon as we get the bike back on the dyno.
For the rolling chassis, our plans include:
¨ Rework the front forks to make them more suitable for our chassis. After some initial modifications to the forks themselves, Maxton Engineering will be asked to work their usual magic. One issue we had was that we could only use about 50% of the available front wheel travel.
¨ Modify the headstock area to reduce the weight of the frame and allow the air to enter the airbox through the headstock. At the same time, a method for changing the front wheel trail or yoke offset will be implemented.
¨ Fabricate a new airbox and air conveyor from pre-preg carbon fibre with the air conveyor also replacing the existing front subframe, i.e becoming a structural component supporting the front fairing and providing mounts for the instrument panel and ECU.
¨ Modify the current tank to accommodate the new airbox and move the fuel further towards the centre of the engine.
¨ Identify any opportunities to further reduce weight.
If we can execute to plan, we should get tantalizingly close to our initial goal of 95 kg and 95 HP!
