General topics » Starter clutch noise

Hi all

My starter clutch ( I think that it what it is called) has been making a loud whine on start up and shut down for ages. My new battery is already failing and I have been told it could be to do with this issue also(edited....may be the starter clutch not the battery failing)

I found a used one online from a 2014 GS, but just wanted to make sure they are the same model before purchasing.

Any ideas?

Nobody else had this issue? I have been told it´s a very common fault on the BMW´s.

Hi guys I added a videoclip of the noise just incase anyone recognises it and can tell me which part I need to change so I can get it sorted. It´s actually worse than this now, this was taken a while ago.

Cheers

I am presuming the GS 1200 starter motor is the same on the RS. If so have a look at this,

At the end of the rebuild it show the 'dog' gear operation. These can sometimes whine upon release.
They don't like excessive lubrication, as dirt gets picked up on the shaft and can prevent a clean engagement.
Your bike has a chequered history so it might be worth removing the starter and looking for water damage or other wear.

Not really anyone that I would trust, and that includes main dealer. When I bought the bike they said I had front suspension issues and would need dismantling, turns out it was just the wind screen making a noise when going over certain bumps.

Thanks I will have a look.

Lee might be able to look at his workshop manual/parts fiche to see if the starters are similar.
Your comment that the whine is present when you stop the bike makes me wonder if there is a different type of dog gear engagement on the RS.

The strange thing is that it doesn’t always
Whine on shut off. It’s kind of 50-50 whether it will happen.

If so does the drawing show additional mesh gearing?

What does any of this mean guys?

Would changing the starter motor solve the problem or is the starter clutch something else?
HELP! lol
