Strange engine squeel

My T509 Speed Triple (97 injection) has started to make a strange squeeling noise.
It appears to come from the left hand side of the engine. It can only be heard at low speed and doesn't seem to affect performance. The alternator has been checked.
I have had it checked twice by the garage and they can't find anything wrong but it drives me mad!
The bike has only done 10,000 miles.
Please, has anyone got any ideas?

 

Is the garage a Triumph garage or a back streeter??
You say the alternator has been checked,I assume you mean for the loose bolt syndrome that affects some bikes,usually though the noise is not a squeal but a knock.I have seen in other forums that if you turn your lights on while the noise is happening and it goes away that can prove it is the bolt holding the alternator worked loose.

 

Thanks for the reply, it has been to both a main dealer and an independant garage. The alternator was removed, tested and refitted. I forgot to say that the noise only happens when being ridden and not when stationary. It is also doesn't happen all the time.(More annoying! But more often than not!!) Any help would be appreciated. Thanks Joss

 

Its not the brakes is it ??

 

Take it to a Triumph expert like Clive Wood in Swineshead Lincolnshire if he is close to you. 07752477738

 

Unfortunately not!

 

I wish he was nearer as I am in Loughborough, Leicestershire.

 

Anyone know of a good bike mechanic in the Loughborough area?

 

You cannot get noise from engine running at different RPM when bike stationary ???

 

No Peter, that is why I put " I forgot to say that the noise only happens when being ridden and not when stationary"
Thanks Joss

 

could it be anything to do with final drive sprocket. when running engine with bike stationary are you engaging gears or just going through them with clutch in?

 

I can see why it is hard to locate, can you reproduce noise while riding when you want to or doe's it come up on its own accord.

 

Well that's very close compared to some of his customers from all over UK and Ireland.
about an hour away go to Melton then Grantham then along the A52 to Swineshead.
He will look after you for sure. Ask him nice and may even look at it on a evening now the longer nights are here

 

Hi Peter, I can't seem to make it do it when I want to. Just happens when it wants, that is what drives me mad! Joss

 

Thanks, I think I may have a run over to see him in the summer. Joss

 

Please try this to see if you get the same noise you are hearing its worth a try, put bike in a garage if you can, turn ignition on and you should hear fuel pump run and stop(do not start engine) turn off ignition and on again run pump again and then again when the pressure reaches max line pressure the relief valve will activate to return fuel to tank it maybe that the valve on your bike has got noisy, after doing this start and run engine till normal working temperature is reached just to get rid of fuel line pressure.

 

Thanks Peter, I will try this at the weekend and let you know.

 

Do you fill in an additive to your engine oil ??

 

No mate

 

Was the dealer you tried Pidcocks Nottingham? The old guy in their shop certainly knows his stuff and should be able to help.
