    I'm topping out at 7800 rpm. I have a high compression head and expansion chamber exhaust and high performance CDI. I have also cut the piston. How much can I increase the rpm if:

    1. I replace my NT carb. If so, with what CARB?
    2. Raise the exhaust. If so, by how much?

    Any other suggestions? I don't want to lose low end tongue. I've got great uphill speed and power right now.
