Thanks for the detailed reply Richard!

I thought those headers looks coated. Nice.
Good luck with your composites.

Battyone is bang on with his comments regarding de-gassing, it's been a problem for boat builders for quite some time.
For messing about with carbon and epoxy, you realy need a vac pump.
Regarding the wavey discs, I spoke to the Guys who have been making the brake parts for my car project last week, they also do stuff for Moto GP and BSB, and as I suspected they can't see why there would be any advantage with them.
I would rather believe those Guys than the marketing video.
Oh and I got to ride my bike for the first time.
First impression, loads of torque, nice. Second impression, fook! The brakes are crap!
Regards,
Mick.
