    Throttle body boring - gains?

    For the older/non X skis, is throttle body boring worthwhile? Best place to have it done? Do you need to send it somewhere to get a larger throttle blade too, or is just the taper boring good enough?

    All I remember is that some said it helps acceleration mostly ... does it add rpm on top too?

    maxbore does a great job
    but the gains IMO can not be felt

    Did Ross's mod first, then Maxbore, then opened up the intake.

    Do you think that Yamahas 1.8l will need a tps reset? Do they offer a reset? Thanks

    think more is gained from torque plate than a throttle body mod IMO.

    I run aftermarket one on my turbo which is waay bigger than stock
