BMW R1100S not starting

[nitro1980]

Hi my bike is not starting normally, you turn it on and hear the fuel pump charge but when I press the starter button you just hear a clunk.

It has a;
* new battery which I've checked is fully charged.
* new engine oil filter & oil.
* new spark plugs.
* new fuel filter.
* cleaned K&N air filter.
* & passed it's MOT 1 month before it stopped starting.

Bike: BMW R1100S
Yr: 1999
Mileage: 57,000

To get it going I can bump start the bike to get it going. Once going it does seem to idle a higher than normal. However the bike now seems to over-heat easily which I believe is connected to the high idle but not 100% sure.

I'm thinking this could be the starter motor or wires connecting to it, would this seem about right?

Any suggestions on why the idle is higher than normal or alternative suggestions on why it's over heating?

Thanks
Dave

When you press the starter, is it actually a 'clunk' or is it more like a loudish 'click'?

You said it has a new battery, was the old battery getting very tired? Using a nearly duff battery can make the starter solenoid unhappy.

None of the other things you've listed would affect the operation of the starter, unless someone particularly hamfisted buggered something while changing those things...

For the high idle and overheating - is the oil level correct? How was the k&n filter cleaned and was it re-oiled afterwards? (k&n is a complete waste of time on the vast majority of BMWs by the way, there is no lack of flow on the OEM units but the k&n lets through more crap).

When the new oil filter was fitted, did it have any stickers etc. stuck to the outside of it and if so, were they removed?

Passing an MOT means the square root of fuck all when it comes to the operation of a bike - it's minimum roadworthy standard check, not a pre-sales and service inspection. In fact, passing an MOT doesn't mean much at all any time......

If you can't fix it and get fed up, I'll give you 50quid for the bike

Thanks Dave, yes I have used Motorworks for many parts over the years and I'd say the bike is now 10% supplied by them, good set of guys there.

Hi pdg, yes I'd say more of a clunk than a click. Fitted a new battery as the bike had been previously SORN and I'd not kept up a charge on the battery so the old battery was goosed. Don't think I have hamfisted anything, but I'll soon know when I get time to strip it down.
Oil level is correct and the k&n was re-oiled, I've never had an issue with K&n and they save me re-buying a new filter everytime, it was not bought for any performance reasons.
Can't remember there being any stickers etc on the oil filter, was bought from Motorworks along with the oil, so I'm sure it's exactly what it should be.
Hmm, thanks very much for the offer but I'll have to refuse your generous offer of 50quid.

Thanks all, although the oil was just at the max mark, I reduced this slightly and that seems to have solved the over heating issues, won't be so generous next time

Still need to strip bits down, including the starter motor as it's not as efficient as it was and power supply to it seems ok, but will leave that for winter now.

Thanks again.
