2019 fx svho problem

[Timmymajic]

My 2019 fx svho which has 5 hours on hasn’t just developed a problem I’m not sure if it’s 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 wouldn’t 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. It’s 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.
you think it’s clutch then?

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

Did you check all hoses

[Timmymajic]

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!
