    15f throttle response

    hi, i bought this 2006 stx 15f, the fuel was a little like mud, gutted and cleaned it all, the tank, lines, injector rail and injectors and now runs better but.. there is litterally a whole 1 second delay from pulling the throttle to the revs going up.
    any ideas?

    Sounds like it's still low on fuel delivery. Did you change out the inline fuel filter as well? Put a fuel pressure gauge on it. The fuel pump might be screwed up as well. Should be a constant 43psi.

    I cleaned the online filter to what looked like a very acceptable level. I don't have a gauge but will post back when I get this checked. I have just bought a replacement rail and injectors so will see if this does anything.

    The fuel filter that is just under the small storage box in front of the seat cannot be cleaned, but you can check it & see if it flows ok, if not replace it. I have never had a throttle response problem with mine, but I did replace the filter & after that I noticed a very slight improvement in throttle response & a little increase in top speed RPM.
