    Strange noise after ignition

    Noticed lately that after turning key on and pushing the starter button and bike fires, there is an after squeaky/electric type noise from ( I think) right hand side below tank. It sounds almost like when a car is already running and you try turn the key again. That sort of grhhh noise. Its definitely more pronounced when cold in mornings. Its definitely after ignition and is almost like a connection not being released? Looking to identify it so I can get the part/noise fixed on next service. I don't notice it when bike is warm. Has anyone got any ideas? My guess would be starter motor related issue?

    Not belt. More mechanical. Goes quiet after 1 or 2 seconds. Only when bike cold. Here are 3 videos from this morning. 1 without choke. 1 with choke. Then 1 after 10 minutes of riding. Screech at end of all except the warm start. https://photos.app.goo.gl/yqFeUJu31bLeDe9L7

    Could it be your starter motor not disengaging?

    Starter motor.

    It sounds tired, possibly the fixed grease retaining plate is starting to come loose. See MikeP's starter motor post in the 1100/1150 tips and info section.

    Mine was making this noise. I was told the shaft needed greasing on the starter motor.
    I bought a new starter, got Mikeyboy to fit it, and hey presto, no more noise.

    Yep. I don’t have space, inclination to do this job myself. Reckon I’ll be be buying this for Steptoe to fit at next service. Unless others have a better supplier? https://www.ebay.co.uk/itm/FITS-BMW-...-127635-2958-0

    Fuel pump is on the RH side too... But as above, starter motor is a very likely culprit. Good news is, it's a dead easy job to rejuvenate. Follow Steppers lead

    I won't be rejuvenating it. And Steppers/ any mechanics hourly rate will mean replacement is cheaper than fettling and hoping. If I had my own garage and a second bike, I might faff. But seeing as I don't I'll trust those qualified..And then again, its 20 years old...Some parts are worth replacing at £60

    You're missing a trick here. I kid you not that in 45min - beginning to end - you can rejuvenate that starter motor (I do not mean brushes and magnet service). But I do I mean removal, Bendix/clutch clean and refitting in 45min.

    If it is the starter (which sounds probable) it's very (highly) likely it's just gummed up with dust and grease. And to be precise, I mean the Bendix/clutch mechanism. Really, it's easy and one of those very satisfying jobs.

    You'll kick yourself if you just buy a new starter.

    Ref the grease plate mentioned by Steppers. If that looks like it is the issue (doesn't sound like it tho). Just remove it. Yes, it has a job but it'll work for years without it! Fix at your leisure

    I had the same problem with my 2003 GS in 2007,sometimes the starter would stick, stripped the starter,removed the plate and it has been fine since.
    I stripped it again just before Christmas to check on it and all looked good,cleaned it,greased it up and put it back together,good for another few years.
    Stripping it the first time is a bit harder as there are a couple of rivets to drill out, but using the guide it is quite straightforward.
