    Default Poor throttle response

    Ok so here's a question ...
    so I got this NSR50 for the track how and where adtiry fir another day😎.
    Having poor throttle response
    A having a couple issues so insight is apreicated.

    Getting her to idol consistently
    Poor throttle response under 6,500-7000rpm
    And when throttle is released slow return.
    Now that being said I've pulled the carb and it all appears to be clean and moving smoothly.
    Jets are clean and needles are set to spec.
    I've tried different adjustments but no success so if anyone has any thoughts I'd love to hear them.
    Thanks

    Since I've already sent you a bunch of info via email I'll just post up this link for folks that find this thread. ;)

    And for folks reading this, it's likely an issue with the mixture/pilot jet tuned for the conditions.

    Thanks, cable is pretty new and smooth no slowness or hang ups but shot some cable lube can't hurt.
