First of all, welcome to the forum :hello2: and congratulations on your use of English, it is perfect.

I have listened to the soundtrack and it does seem excessively noisy but this'll is very difficult to offer you a definitive diagnosis from remote.

When it comes to any machinery it is very useful to know the history of the machine and specifically what maintenance has been done and the mileage covered and elapsed since the maintenance.

Looking at your machine it looks as though it has a hard life and has been down the road a few times on parts other than the tyres.

My best advice to you is to examine the CVT assembly, this is very easily and quickly done. My main suspect would be the variator/roller assemblies and perhaps the bearing in the transmission cover. While in there you should of course check the condition of the belt, which may need to be changed. I suspect the transmission housing is very likely full of belt debris.

I would also check for exhaust leaks at the cylinder head joint. not the primary problem here but may be adding to the overall sound levels.

Have a look at micbergsma's video's on You Tube, they are very helpful. I have some pics in my gallery too which show some detail of disassembly but not as good as micbergsma's videos.

By the way, I would not bother trying to ride in that white stuff so you have plenty of time to sort this out. :lol:

I could be wrong on this, but one noise I seem to be picking up sounds like a rattle that may be coming from the exhaust pipe. I had this experience on my bike, and found that some screws had come loose in the tip assembly. On the end there are some Allen head screws, only three of which actually hold the very tip plastic piece on and the rest are for show. Under that is an assembly held on by more screws and when you take those off there's another set of screws. Somewhere in all that you might find one or more that's loosened up or completely come off.

Hi again..
At this moment i have little information about this scooter:
odo: 38 000km (last year), new piston, piston rings, drive belt, pulleys and variable..or variator weights 23gr.
then..my frend drives to 43 000km and suddenly coming that noise...
last night he started engine, and the first 5 minutes was not that noise, then came back...
it can drive both the city and highway, it does not change the voice... friend wants me to sell it because bought a nice new 400 SYM scooter, burgman price about 1200 euros (1 euro= 0.75 usd )

i use littlebit google translator to writing, so I think that it is clear... :wink:

Kaido.

 

[NormanB]

Well as long as the work was done correctly, then there should be no reason why the belt should be suspect.
However, I still stand by my earlier advice to get in there and have a look, as well as check for exhaust leaks at the engine end - and as mentioned previously by Scooter_Maniac check the exhaust end cap.

It would be useful if more experienced 400 owners could help by contributing here. :wink:

Have you checked the engine oil? it sounds more like engine or cam chain noise but very difficult to tell without seeing it live.

 

[Mark-III]

oil and oil level is ok.. something Gulf 10w40 semi synthetic...
next sunday i problably have time to see that scooter, then i see what can happened to next :wink:

 

[Ralph M]

Get a long screw driver and use it like a stethoscope and try to narrow down were the sound comes from.

ok, thanks ... 8)

It sounds really loud and more so up front. It might be the header bolts came loose. My scoot sounded like that after the major service. It's hard to tell, be it also sounds like the belt is worn, the bang bang bang in the background might be the belt slapping against the cvt case. And when that occurs it is also very loud. Good luck!

 

[Scootereno]

It's all guess work until you take it apart and look at all the pieces that come into play.

 

[Mark-III]

Hi everybody!!
currently have my bike repaired, and the reason is the crankshaft bearings is broken... :?
all work and new bearings cost to me finally 500 euros (about 380 $ ) and two weeks time..

sorry for google translation

Kaido.

 

[model28a]

Thank you very much for letting us know the outcome and how you fixed your scooter. :thumbup: So often we get people come here and ask how to fix their scooter and then never come back to let us know how they made out.
And no need to apologize for the google translation, that is just another way to make this big world we live on a little smaller. After all we are all neighbours, only some of us live a little closer than others.

 

[Scootereno]

Glad you were able to find the problem and get it fixed. :thumbup:
To bad it required professional help and money. :?
Ride Safe and Have Fun.

Welcome to the forum...and your English is a hell of a lot better than my Russian or Finnish.....LOL!! I watched the video - and (just my opinion!) It sounds like the muffler has rusted out inside and most or all of the baffles are gone..!!

 

[Mark-III]

thanks my frends!!!
and greetings from Estonia.
Kaido.

 

[johnd]

I am sure it could be noise from the variator outer cone grinding on the alloy housing. Caused by the primary drive nut coming loose. It has happened to me two times. Both times my fault for not tightening the nut correctly.
Good luck with your repairs. johnD

 

[Mark-III]

with my friend, we take all in a parts the CVT section ( removing belt, clutch ...) and still the same voice coming if we starting engine.
then we put back all parts and thinking ...bike needs a proffessional help :roll:

and at this moment bike has a suzuki dealership for repairs..

Kaido.

 

[Mark-III]

meanwhile...this same bike now is mine :thumbup:
price to me 900 euros..(about 685 usd) for that engine problem reason.
