ive seen an oil cooler instead of a front number plate. I would be worried about the risk of it breaking or leaking with disastrous consequences for the engine or my rear wheel's traction. I have also considered a laminova but that is too complicated. Not to mention the weight.

After watching the voltmeter go back up to 13.6 from lower i know that the fan is capable of lowering the engine temp and keeping it there in traffic at idle in British weather.

ducting hot air to the cockpit would be nice. The only large aperture i can think of is the hole above the pedals.

My next project is to duct cool area around the bevel box as mine only makes a noise after sustained load such as motorway or repeated acceleration.
