What's the matter with my Speed Triple?

Morning!

So...I've had my triple a few months now. When I first got her she would start immediately. Recently however, I now have to wait maybe 15-20 seconds before she'll turn over.

This is obviously some electrical glitch, and I can only assume it's to do with the fuel pump/priming or something. When you turn the ignition on, you hear the fuel pump priming and when it's finished the bike will turn over and start. Up until then the starter button does nothing (i.e. doesn't attempt to turn over).

Anyone seen anything like this before? The bike still starts and runs perfectly, just with this 15s delay!

Does the pump always start priming as soon as you turn the key or does it vary by a few seconds each time?

I'd be checking out the kill switch, clutch switch and side stand switch first.

Varies a few seconds. I was thinking it wasn't switch/sensor related...as I can be sat there with my thumb on the starter, no other changes, and as soon as the fuel pump stops (15 secs or so) it fires and starts immediately. Could be wrong, I'm no expert

I think its normal to wait for the fuel pump to prime before turning over no? the issue is I guess priming should take 2-3 seconds not 15-20?

Yes correct, it used to be ignition on, by the time I've depressed the clutch, put the side stand up and moved my hand to the starter it's primed and starts. Now it takes 15 seconds or so.

You should always wait until it's primed before starting it.

Also, check that the battery has full charge.

It happens when cold, or hot. I can stop it after a 30+ mile ride, try to immediately restart it and it takes 15 seconds. Could that still be battery related?

I would expect the starter to be laboured if the battery was going to be the issue as that is more of a strain than the pump priming. If it's taking more time to prime could it be a kink or blockage in the fuel line? But that would probably also be a problem when riding fast?

No issues whatsoever when it's started, redlines fine with no hesitancy *shrug*. I'm minded just to put up with it

 

[killsta]

Are you saying the fuel pump is priming for a full 15 seconds, or that it doesn't start priming until 15 seconds after the ignition is on?

It always starts priming immediately, just now it primes for longer.

Wow all that sounds pretty complicated. Is there anything I can tap with a hammer?

I think I'll take it to someone who knows what they're doing

 

[killsta]

Will do, ta!

No doesn't turn over, the starter button does nothing for about 15 seconds

Hi there. Just wondering if you ever resolved this issue?, Going through it myself at the moment. Thanks

No, I sold it Sorry!

i had this same issue with mine, started doing it one day, it then over time devolved in to maybe waiting up to 2 mins, did clutch switch, start button, sprag, turned out to be the ecu

Sounds expensive.

I chopped mine for a Tiger as I wanted to do more touring anyway
