I have an 05 450r with 13.1iston, venom P&P head with +1 exhaust, hrc header, hmf pipe, HCII cam, 185 main jet, K&N no lid, Dyna non programmable cdi. I am just trying to squeeze some more power in my quad in mid to top end. Is there a big differance in going to a better cdi? maybe vortex or programmable dyna? I have never moved my clip in my carb but this is just low end power from what i understand (could be wrong) but it has great low end power now.
