Anyone know what this is? Everything on the bike is working fine, but when I turn the ignition to the on position I can hear a faint crackling noise, it sounds like it's coming from the tank or clocks area but I can't pin point it... Fzs1000 2002

Mind you I spent about an hour and a bit searching the internet when I first got my Fazer, cos someone said to me that the Exup valve really needs stripping down and cleaning out and lubing each year, as I said an Hour and a bit later I found out that FZS does not have one.

The OP says he has a FZS1000 and has been told that the noise he is hearing is most likely the EXUP cycling so your post is only going to confuse him and anyone else new who reads it. I assume you're talking about the FZS600 in which case you're on the wrong forum.

The bike has a full akrapovic system on it. So no exup. Is there a solenoid hidden somewhere that I should remove? Read a post on the American forum that someone mentioned the sound to do with the "fuel gauge tracer", whatever that is...?

Could be that the exup servo (motor) has been left in with cables disconnected.

Tank off/lifted, ear under tank, ignition on

Cheers

Is the cycling a constant noise? This isn't like a servo sound on a dt125, like a constant crackling...

sadlonelygit · « **Reply #11 on:** 11 February 2016, 01:50:48 pm »

does it sound like a servo cycling when you turn it on. once it's on, you will hear a minute amount of motor noise as it holds a neutral position.

Just done full service inc ais removal makes changing plugs a piece of piss,Just had my servo out of the bike cracked it open greased it all put it back oiled cables , serviced exup too snapped 1 bolt in the exhaust doh
Drilled out re tapped and fresh stainless bolts, put it back together switched ignition on heard a funny noise from the servo thought the worst

took it out opened valve and swithed ignition on and servo returned to neutral position so thats a bonus buzzing was just servo spinning up

Next up ivans jet kit

I had the same sound on one of my fazers. If you squirt electrical lube down the ignition and turn it on and off a few times the noise should go away.

Turn off the engine with the kill switch, now turn off the ignition.
Turn on the ignition is the noise gone?
If so it is the exup servo

Oh I do beg your pardon Pie, I did not realise that if you don't have a 1K fazer your not allowed in this chat, I foolishly thought that the FOC was a club for all Fazer owners (How stupid of me) is it a club for any 1K Fazer owner or is it just a certain model or year or maybe it has to be a certain colour, maybe you are not allowed to post if you don't have a rear hugger or fender extender fitted.
I know mate I sorry as I am now being as big twat as others on here. My apologies

Did you sort the crackling noise out, coz mines doing it now, fzs 1000 2003. Ignition on, then it sounds like a relay clicking once, then the crackling sizzling noise starts until ignition is switched off. Sounds a bit like something arcing or shorting out, hope it's not.......

I had something similar and ended up replacing the battery which resolved the issue.

windscreenman · « **Reply #18 on:** 16 February 2016, 11:59:06 pm »

Mines got a new battery on and it's still doing it it's the exup servo the grease inside is very sticky and it sounds Like it's clicking as the cogs spin uplift the tank and feel the servo for vibrations to check operation ignition off turn wheel on servo to open valve then switch ignition back on if it returns to original setting put your tank back down and don't worry about it

Motopsycho87 · « **Reply #19 on:** 17 February 2016, 03:58:38 am »

Nope, not sorted it yet, but what you are describing is exactly what I'm getting, more of a constant sizzling noise. I've changed the battery recently, and starter relay, so nothing to do with them (didn't think it would be anyway!) But I'll get to the source of it hopefully this evening, as I'll have it apart to balance the carbs anyway!

windscreenman · « **Reply #20 on:** 17 February 2016, 07:42:48 am »

You could remove the servo or unplug it if not required mines done 31kand when I opened the servo the grease was like black thick sticky as the cogs unmesh that's where my crackling noise was coming from I still got exup so I need mine but it's nothing to worry about honest

Lift tank and feel servo you can feel it working if your hearing isn't clever put a screwdriver on servo and put the handle to your ear that will amplify your crackling

Motopsycho87 · « **Reply #21 on:** 18 February 2016, 08:22:09 pm »

It didn't crackle when I balanced the carbs so I left it. I know it still does it, but when cold apparently... Servo is there, that can bugger off shortly

Fazerjon · « **Reply #22 on:** 19 February 2016, 09:42:22 am »

I disconnected my servo earlier as I also have the crackling noise, and it sure enough it stopped. Definitely not a healthy sound, I don't like it. Anyway if everyone reckons its normal then I'll leave it. One question, is the servo supposed to do a cycle every time the ignition is switched on? I've greased up the valve, checked the cables and that end is all good. I've oiled the cables at the servo end, but when I switch the ignition on nothing moves, just crackles??

Motopsycho87 · « **Reply #23 on:** 19 February 2016, 01:29:43 pm »

I take there is no harm in removing the servo? Just eating my precious electricity otherwise...

And I've never come across anything electrical where that noise is a good thing!

Turn off the engine with the kill switch, now turn off the ignition.
Turn on the ignition is the noise gone?
If so it is the exup servo

Try the above if it goes away then it is the servo going into its default position which it does when you stop the engine with the kill switch.
When you stop the engine with the ignition key the power is cut and the Exup cannot return to its default position until you switch the ignition back on.
