If it's like my '03 I wouldn't ride it. I had the belt squeak noise and rode it till the bearing failed taking out the primary pulley splines.

 

Ray,

is it a constant squealing sound or doesn't happen when you start up the scoot on a cold start and goes away after it is all warmed up.

not a whole lot you can do except to take it apart and start inspecting parts.

If it is a failing bearing, it will go out at some point... the earlier 03/04 seem to suffer a bit more from bearing failures here and there.

if the scoot is operating normally and the noise is intermittent at best, ride it and enjoy it until it becomes a real problem.

I have a std 04 with 54k miles on it and every now and then it will squeak on a cold start, but goes away once the wheel starts to turn.

good luck....

 

The squeak is there pretty much all the time.

 

The squeak is there pretty much all the time.

that could be a tell tell sign of a failing bearing ... hard to diagnose anything from just a sound...

you can take the tupperware off and see if you can locate where the sound is coming from...

you may want to consult your service manual before dumping a cup of oil or anything in there...
got to ask yourself where will all that oil end up and what else will it affect....

good luck....

ps: have you by any chance checked/replaced the rear wheel bearings?

 

I've taken the plastic off and tried to listen using a screw driver against the transmission, but haven't yet been able to pin point the source. I have not checked or replaced the wheel bearings.

 

In the photo below directly across from where the magneto wires come out you can see where the CVT input is and that's where you would want to listen for bearing grinding/squeaking noise.

My noise (light chirping/squeak like a loose belt on a car) started somewhere around your current mileage. I could only hear it idling with my helmet off. Mine failed stripping the splines at 26,228 miles on the odometer. I was riding into work, just rounded a corner, bang, grinding noise, coasted to the curb and shut it off. When I restarted it the engine would rev freely with no forward motion. Pulling the little cover off you could see the primary adapter bolt had spun on the gear. With it running the gear turned but not the bolt. I put a socket on the bolt (which was tight) and turning it spun the rear wheel and not the adapter gear.

 

Sorry for my ignorance, but I don't know which one is the magneto wire. Would you be listening on the right or left side of the bike? Thanks

 

Maybe this picture will help. It's from when I pulled the CVT out of my 07 so the cover shape is slightly different than on your 03 but it is in the same place. Look just to the right of the frame where the yellow drop light cord crosses it.

Sorry the wires with the yellow tape, in fact you can see one of them laying on the CVT at the right. You actually want to listen between the engine case and CVT case. I'll get a better photo for you tonight.

 

Actually it looks easier to listen from underneath with a mechanic's stethoscope. Here's a photo (mind you the exhaust is removed in this photo), hope it helps.

 

Been a while, any word Ray?

 

Hello Guys from Greece.
I recently bought a friend 08 Burgie and since new it make a strange sound on idle (only if the rear wheel is stopped). Suzuki has checked it over and over and said its normal, even though they have replaced the gears inside once, just to make sure.
This is a video of the sound and i would appreciate any help. I just hope i posted on the right place.

I thank you all for your help and input!

 

The noise is the drive belt in the CVT slipping momentarily. If you are playing with the Power or D-M buttons when it makes the noise it is totally normal. If you are not playing with those buttons and it is making that noise then something is wrong. The noise is the belt slipping as the CVT motor adjusts the primary pulley and the secondary pulley with the spring tensioner catches up.

 

I have a sound towards the back of the bike when I take off, but it goes right away. it's the same type squeaking sound. should I think this is a major problem?

 

Does it make the noise while idling on the center stand without the brake on and the wheel turning?

 

@MJR no I doesn't. just a take off then it stops right away

 

See if it changes if you switch to Power or Manual mode and start out.

 

Just another idea, check that the rear brake pads aren't down to the shim plate.... which is the thin metal piece that provides an audible warning when the pads are getting low...
Also while I'm thinking a loud, how about checking the final drive oil... doubtful but wouldn't hurt to check just in case it's dry in there...
And assume you have checked between the manual and auto modes... as when one changes over between the two modes there is a audible squeal momentarily as the transmission switches between the two modes. If you try this, is this sound similar to what you hear?

My '09 would have a light sqeak on the centerstand idling which was just something in the pads which didn't bother me enough to replace them as they still had meat on them.

 

Hello Friends and Thanx for your replies!
Let me try and make thing clear.
The bike has this noise since it had 0Km on it. Has been to Suzuki 5-6 times for it and they call it normal noise ????
Mostly you hear the noise while on Auto mode no matter if you have Power on or off and seems to almost disappear when on Manual mode. All this with the rear wheel on the ground or with the wheel stopped while on center stand. Suzuki Dealer opened it up at almost 10000Km and found everything in perfect shape and after my friends pressure only replaced within warranty the plastic gears. Now after talking with you guys here and with a friend in Japan that showed this video to a Suzuki Dealer, i am 100% sure there is something wrong but i just wanted to maybe narrow it down so i can pressure to review it again and based on bikes history finally fix it without charging me an arm an a leg for it. My feeling, even though a Burgie Newbie.... is that one of the following might be wrong:
a) CVT sensor.
b) CVT motor that maintains the pressure on the belt.
c) CVT Belt
The above with exactly the order i typed them! One last thing is while being on the bike in auto mode (wheel on the ground) if i switch to manual i can hear this sound once again maybe 5-10% stronger and if i stay on manual, 99% of the times after that i dont hear this noise again unless i switch back to Auto.
Thats all and thanx for your help again!

 

Tensioning of the drive belt is handled by the big spring on the secondary pulley assembly.

My first thoughts would be either a stretched/mismanufactured drive belt, weak spring on the secondary pulley assembly, a bad bearing, or maybe something on the pulley surfaces. It's even possible the noise isn't in the CVT but engine.

 

what about a squeak when you accellerate at a stand still; about 1 second and no squeak when bike on centerstand and revving?

 

what about a 1 second squeak when accelerating from a standstill and no squeak when scooter on centerstand while revving?

 

Can't say I've noticed any such thing but with a helmet on I can't hear light squeaks. Its one of those things that without seeing/hearing for myself in person is hard to say. My suggestion would be to find someone local with the same bike and compare yours with theirs.
