My 08 has developed an uneven/noisey tickover and removal of the cover, clutch, belt etc reveal nothing broken.

The only thing my local (reliable) mechanic has found is, wear grooves on the front drive pulley, which in his opinion, could be setting up an 'out of balance' noise, as the belt is spinning at its slowest rpm.

The scoot runs smooth and quiet after take off, with no other issues on an otherwise very good condition, and well looked after bike.

Thoughts please guys. (sorry about the typo in the heading (Grooves)

it's normal and resurfacing the plates just means the rest of the plate is now thinner too, like your wallet

Odd you mention this, mine is noisier at tick over and my variator is a little worn, interesting thought. How many miles has yours done, any ideas where to get a replacement variator in UK?

Groves are normal on CVT clutches and do not produce any noise to the best of my knowledge.

I would blow out the dust and see the running will be quieter as a normal grooved front pulley will not make noise as the belt being rubber would absorb it if it did if their is noise it would be due to only one thing and that is if the front and rear pulleys are misaligned by a shim washer being accidentally installed behind one or the other. the noise would not be due to grooves but a harmonic frequency caused by different pressures to both sides of the belt which will increase as the belt wears.

Dave, looking in the transmission case is not my first thought to find the problem causing this. However, a couple of questions to ask if I may.

1. Does the uneven tick over occur when the engine is cold, hot, or is it there all the time?

2. What sort of sound is the noisy tick over making? Metallic ticking, rattling etc? Can you describe it more accurately?

If the engine is ticking over unevenly, the transmissions WILL be noisy. That happens with CVT of the type we have. Some ribbing of the pulley's is probably not going to cause the engine to run unevenly at tick over as ribbing occurs in areas of the pulleys where most load is most often applied, and that's not tick over. I reckon the problem is the engine itself and may just be as simple as chucking some 'seafoam' into it to clean up the injector and valves. But give us some more info if you can about the kind of noise it makes.

Thanks for the comments guys....the latest situation is this.....

When I collected the scoot after having the drive pulley replaced, the mechanic told me he could find nothing wrong with it, and he was at a loss as to why it was so noisey.

He ran the engine without the drive belt and said it was running sweet, the clutch was recently replaced with the latest 5 shoe part, and the rest of the checks just showed nothing wrong.

Anyway....after paying my £352 bill, and not being happy that nothing was found, I rode up to my other suzuki dealer, asked him how much he would give me for it part exchange for the 2013 400ZA, (ABS, heated grips, etc).....and the deal was done.

I'm now in the process of 'running in' my new white 400, and very happy with it.

If anyone thinks thats an expensive way of 'getting rid of a noise' you're right, but as I look at things now, our money is sitting in a bank account, just losing value as the days go by......I'd rather spend it on something that I want.....you only live once!!

Happy bunny now

Pardon my southern USA intelligence but what do you mean by "tick over" ? Curious minds want to know.

 

[Mike337]

Hahahahahaha Dave. I bought a new truck once like that too when they wanted 5 grand to paint my old one, bought one that's painted already, problem solved!

"tickover" means "idling" in the UK, Oz and most other English speaking countries.

Gary-- Thanks for the reply. I thought that was what it meant but was not sure. Now I know.

Ha Ha...nice one Mike......I've posted a couple of pics in the 'new gallery' if you fancy a look at my 'new paint !

That's rather a splendid way of getting rid of the problem. I approve! And yes, over here in the Uk money in the bank aint good right now. Best spend it. You will love the toys on the 400za abs. I love mine too!
