RSV1000 2003 Stuttering and surging. Scary :(

[Marmaduke]

Only had it a week, all running great until today. Only thing I've done is ACF it and remove the akrapovic sound reducer things.

It revs freely to the redline but when driving along at a sustained speed every now and then I'll just lose all power for half a second and it just generally doesn't feel as smooth. Makes for a scary ride when doing tighter corners.

Got a full akra system and a power commander.

Only has 13k miles, should I just start by replacing the fuel filter?
I'll check that the sidestand switch isn't flakey first though.


HEEELLLPPPP

For anyone searching the same problem I replaced the filter and all seems good so far.

Except.....I left the tank upside and some petrol poured out and has made quite a bit of the lacquer peel off....

Possible to just spot apply more?

Why on earth do people leave tanks upside down?

I thought it was empty and it balanced easier haha!
And it makes getting the pump and filter out from the bottom more manageable.
