    Odd little backfire / Exhaust Popping ?

    Hey

    Got a 16PX 300, Retainers, Riva Intake, 8600rpm Tune, Solas prop

    I noticed something today when its out of the water and running on the hose if i give it tiny little revs, i get like a backfire pop - definitely never noticed that before

    Video shows the popping


    If i give it a normal rev (like anything over say 10% throttle), it wont do it, but say a 5- 10% throttle really quick little throttle blip makes it do it

    Sounds like fuel popping i guess? could it be a combination of me doing such tiny blips, and perhaps the tune jsut being a little rich down low?

    thanks

    If you are explaining what I think you are then yes itís normal , what you should be cautious about is reving it to much or having it on the hose for 2 long .
