    2019 fx svho problem

    My 2019 fx svho which has 5 hours on hasnít just developed a problem Iím not sure if itís the clutch gone bad. It was running fine for an hour or so I then put the riva stock race tune on it pulled hard for about 5 seconds and then dropped to probably around 30mph and wouldnít go any faster but if I let of the gas let it tickover and then go again it does the same again and just keeps doing that I always thought if the clutch went that was it but can they fail intermittently like this? I tried another tune just to verify but it was the same. Itís not misfiring just feels completely flat with no power.

    It just has a riva air filter and solas 13/19 everything else bone stock I have a fizzle blowoff with turbosmart ready to fit but hadn’t got round to it yet.

    Timmy, I hope that "13/19" is repitched to that angle and not a YS-CD 13/19.

    Did you check all hoses

    Yea I’m pretty sure it was a 13/20 I had pitched a couple of years ago on my old fx.
    do they make a 13/19 then? What’s the problem with the ys-cd 13/19?
    yes checked all hoses I was hoping it was the intake tube on bottom of the throttle body but it wasn’t.

    The Solas 13/19 is a 155mm impeller. Surley, that'll make you slow.

    I just had the same problem after stage 1 tune and it was just the throttle body hose popped off!
