Hi all,

I just had my 30K service on my 09 R3, and noticed a new sound when powering the bike up.

When I turn the key, the usual powerup/whirring sounds happen but then I get a repeated pulsing whirring sound from under the left side of the tank. It sounds like pump shooting short pulses of fuel or something. I let it sit powered up, but not running for a few minutes and the sounds does not stop BUT, if I ride the bike for 10-15 minutes, shut her down, and power her up, it does not repeat the sound. It seems to only happen from a cold start.

Is this the pump priming fuel or something? It doesn't have any effect on the ride or feel of the bike and there are no other issues.

They did the standard 30k service and also loaded in the Triumph aftermarket pipe tune in for me. Other than that, nothing has changed.

Thanks,
Paul
 
Sorry , can't help with that one. I'd be taking it back to the shop that did the work .. have to be something they have done (or have not done up) you'd reckon. Let us know the outcome.
 
Only thing I can think of is the stepper motor or some kind of choke mech for cold stating.... I am at a loss to help any further tho....

Take it back to Dealer as TC said, It should not be doing it, they may have loaded a corrupt copy of the Tune, at a guess it sounds like a stepper motor trying to find home base, maybe?
only guessing with out actually being there to hear it
 
Your idle stepper is not set correctly. Take it back and have them redo it. I had mine doing that while experimenting with the idle stepper settings.
 
Called the shop, Blackfoot Motosports here in Calgary. They said "no problem, bring it by". I'll shoot a small video of the sound/behavior to show them becuase you know it won't do it when the bike is hot. At least they're going to look after it.
