I'll call Eric and ask him if he'll use the GP one. I'll see what he says.
I'm interested to see what he'll do to the ports. Told him I wanted it to stay 125, but rip. And it's an MX bike, so all this talk about "good low end yada yada" is out the window, because if you are under 8,000rpms on a 125, you're doing something wrong, or you're in the pits. Take your pick.
