I have a 2006 yfz 450 with a bore kit, race cams, Polished and ported head, oversized values, jet ket, aftermarket exhaust systems and pro flow intake clamp, has about 9 hours on the motor. This quad is pretty maxed out and I been thinking about getting a dynatek cdi and was just tryna see if anyone has seen results and is it worth it lol

We'll I've heard that an aftermarket cdi wears your motor out if you raise the max rpm, however if you have an aftermarket head, you could possibly see high end power gains. If you're really looking for gains, you can get a high compression piston, and run higher octane gas like 110 octane or ethanol. If you don't want to do that, I'd consider building a banshee. Haha
