Nice link thank you

But have decided against bike engine power as while it makes huge sense for power to wieght

two factors go against it.

Not very nice for a long treck that i do occasionaly like to amersfoort (Tempted to do that though not sure where to put an empeg in a car with no dash, no doors, no boot,)

I drive a diesel as an every day car a very good diesel but still a huge torquey diesel i can reprogram to car engines just i stalled the caterham demostrator twice and an elise once but a bike engine to much reprogramming.

But shall pay a visit when i return

anyone fancy a track day up north ?
