Popping noise on a '06 GXSR 750?

[Tricki]

My nephew's Gixxer 750 makes a funny popping noise when you turn the key to the "on" position. It is an eletrical popping noise and coming from underneath the rear cowl. The fuel injection switch is on as well. Anyone know what this may be? I noticed the noise when we installed a license plate light. All the lights and signals work properly. I checked the fuses too. I haven't a clue what it may be.

Sounds like there's some bare wires shorting out or something is hooked up incorrectly

[Tricki]

Patrick...maybe so but I only touched the stock license plate light. And I reversed the wiring to see if I crosswired the two. But still got the popping noise. All lighting and signals work fine though.

its a loose connection or a stripped wire open it up and check the wires and harness closely . my headlights started popping the other night and it turned out my harness was jacked up .

yah, it might be a wire grounded out and arking somewhere. do it at night and look for a spark.

Holly $h!t its a bomb Run for your LIFE!!!!!!!!!!!!!!!!!!!!!!!!!!!!:confused2

[bikerboyz]

its a bomb run for it :laughing6 JK hope you get it fixed

Is it freom the rear cowl or somewhere under the tail section.
Check the simple things first:
Are the battery cables tight?
Are the cable going to the starter relay tight?
Are the wires going into the regualtor rectifier plug in good shape / not melted?
Is the regulator / rectifier still mounted? (don't laugh, I've seen them vibrate loose.)

Beyond that it's difficult to diagnose over the internet.
If you want, bring it by Tuesday when we reopen and I'll check it out real quick. No charge.

I was also told it may be a relay. The contacts may need to be cleaned or the relay replaced. It should be covered by the warranty. Bike is only a few monthes old without any mods.

wont be covered with the warrenty,u altered with the wiring,and they will say that is what caused the problem,so i would forget about that one,it may be all stock but you messed with it instead of taking it to a authorized dealer.well good luck on the problem.

that bike does not have an exhaust valve correct?

[Patrick]

It does have an exhaust valve and actuator motor.

if thats the case he could be hearing the actuator moving... it does a self test when u turn the key i believe

[Patrick]

You may have a good point.

Sorry for the off topic post but tricki if you ever wreck that bike on the left side and the rights still good give me a pm...

[gsxr2404]

No prob.......Mr. B.S.! I hope that doesn't occur though!

[Tricki]

OOops! B.S. ....That was me "Tricki" which made that last comment not gsxr2404 ... I forgot to log my nephew out and log myself in! We got 2 MH members in the family!

[Patrick]

What did you guys find out?

[Tricki]

We are gonna drop off the bike at the authorized dealer this weekend. The fuel injection light is coming on also. So we should find out the problem soon. I'll let you guys know the outcome! Thanks for everyone's input. Though I don't believe it is a bomb! .........lol

[Tricki]

OK...I took the bike in and the service mgr. said the problem was the actuator valve. I let them listen to the noise when I dropped the bike off. He also said it was covered by the warranty and they will take care of it. So corey and Patrick you guys were thinking correctly. And Rick, they didn't hassel me at all about removing the mud flap and installing a new license plate light! Can you believe that!

[c0rey]

good to hear they didn't give u mess about the mudflap....thats always got to be the first thing to go lol
