Roadside bodging (first and second gears not selecting)

Impressive CAD there!
What are the twin helical structures under the left of the motor?

Interesting that you're using the BMW-style single sided swingarm!

What CAD program did you use for that?

Specs?

The spiral things are the rotors of the supercharger. It's a sleeve-valve V6 2-stroke, more or less a copy of the Rolls Royce Crecy, which would have been the successor to the Merlin. This is just a scaled-down version. I'm guessing that modern metallurgy and fuelling technology (it's direct injection) would help it all along.
This thing is 800cc and would produce about 250bhp @8000rpm. This would have a bmep of just under 200psi, which isn't much. And without all the friction and pumping losses of a 4-stroke, the amount of heat produced wouldn't be excessive either. It works like this.



It'd just cost about 250,000 euro to make, which is why it won't happen. At least, not this year.  The CAD program is Solidworks.

Beautifully detailled model!

Guessing you're a final year engineering student like me - where and what are you studying?

Bloody hell, what do you do with your gear lever?!?  :eek

Just out of curiosity, you do ride with your foot well clear of the shifter, right?

Behind his head clear enough? Every biker should practice yoga

My only conclusion is that you're either REALLY heavy-footed.

Lay down and let Fazerider show

I wish.  I don't have the handle oldbastard for nothing. But I appear to have hijacked the thread. Apologies.
