Sorry about that - thought you were saying I couldn't build a heat shield, lol!
Which way would you think to route them? I'm pretty much convinced the stock routing is the most 'efficient' as far as layout goes, but I'd entertain other ideas.
Going down around the crank would be another viable option - I just think the intake would be in the way on the other side of the motor.
