94 1100GS not starting from cold!

im currently having starter motor check out (just because it is VERY noisy when turning bike over) although as steve says it has only just been rebuilt.

probably nothing to do with the starting problem, but that stands out to me.
 
Ok we are getting there,well..?

Peep me old mate,
Your Battery checks out. Now the charging system?/ OK ?
When you do get the Bike Running and it is Warm. By moving the "choke lever" and it is back at rest ( not off) does the Revs pick- up? See a lot of Folk Balance the Bodies ok. But don't set up the "choke" throttle lifter / fast iddle?
Also when running just touch the side stand down a bit, like one finger on it? Does it cut out. Wiggle the switch does it cut out? No. The side stand switch is ok then..yes I know they give problem but the Previous owner had none.
Which brings me back to "The age old question"..? What have YOU done to the bike since the old owner handed it over? Sorry if I offend you. But I have had bikes and their Riders pop in with similar problems. Because they cleaned something? Washed this bit? Put fuel lines on wrong after having the tank off?( not your prob by the way) All that sought of stuff? It's True and so easy to do with a new bike.
Grab the old owner ( who seams a nice bloke) and start the bike ( COLD) infront of him.
Many new owners just don't treat the Lady the same. Poor thing is terrified of being Burnt? Hee, hee. Keep in touch. Bigjim.

thanks Jim,
ive charged battery, tightened the alternator belt, had the starter motor rebuilt(had come apart inside and shorted out the armerture),choke does make it rev higher,side stand switch is working. ive not done anything to the bike at all not even cleaned it after i got it home.
when i get info on balancing thottle bodies i will do that, and also check the oil temp sensor
:beerjug:

ITS ALL A BIT OF A MYSTERY
i may have to book it in somewhere
 
Can anyone tell me where the oil temp sensor is cant find it on bike or in BMW or haynes manual:confused::confused: found it on wiring diagram but no location:confused:
 
No probs..

O k new one. Listen-up one and all.
Bm ( 1100 I know) has a Oil Pressure switch on the 1100 it is NOT a Cut Out Switch It's Low it's on but Bike will run ok? Not like ?? English stuff, me thinking... eg Landies/ Defenders Range Rovers have an Oil Switch with 2 wires and 2 jobs it detects Low Oil and SHUTS DOWN the Management System when the oil is really Low. Next door Broke that one wire Washing his engine. I offered $100 for his V8 Disco... another story. Yeah ok ...I fixed it for a Beer or 4...:beerjug: Not a complete Bugger me not...
Oil Cut out on you'r NO ! Bm does NOT. You The Rider must Shut it Down!! Read you Haynes Manual 8:3 ( -16 Oil Pressure switch ).
No probs. Service Day today on my own work van Wifes Car and Gs. So better open up the workshop and "Get Cracking Gromit". BJ
 
Woops...

You have got it starting and Riding ok ? Still faulting with electrics? Starter motor sounded stuffed? They are BIG Power Drain when not working propper. If that's the case pick a Nice Local Loop and go and discover all about Gs ing. Keep cool and pleased to help.

got starter motor fixed it was shorting out. found out the spark plugs are not the exact ones for this bike. im currently running NGK BCPR6ES and they should be either BOSCH FR5DTC or NGK BCPR7ET. I HOPE THIS WILL IMPROVE COLD START .:thumb fingers crossed
 
Did you ever do a code read, it was the most important & easy thing i did & you ony need a cheap analog multi meter to do it
 
I have fitted a new oil temp sensor to my 1100 now and its cured. The sensor is on the top of the engine off side hidden behind some breather pipes.If you replace it get a new alloy washer aswell, one dosent come with it. the spare ones that come with a bm oil filter fit though.

Did you get it going OK Ian? What was it in the end?

Steve

i find out tomorrow for sure but had to give it to BGM in kent to sort out. had starter rebuilt again as previous rebuild fell apart (literally) and was shorting out. left hand cylinder gasget has blown badly, so will have both replaced. starting fault as predicted here by KTMMARK:thumb is very proberbly HALL sensor . oh and Brian thinks its still running origial fuel filter as current one has turned itsself inside out and needs rear pads...........thats it ....:spitfire
may have some change from £600??? for some tissues:thedummy:thedummy

unlucky hey

Bloody hell - how the hell did it get you home? The Starter motor was still under guarantee so I hope you claimed.I knew the fuel filter was due for replacement - there was a new one in the pile of bits.
I'll bow to the mechanics superior knowledge on the Hall Sensor but didnt it run OK once you'd bumped it?
At least theres not much left to go wrong!
 
Peepingtom - you're not having much luck are you. What time did you get home last night? :nenau It was good to put a face to the name - pity about your puncture though.

Had a good but uneventful run home myself - eventually got in at 2.30am this morning. :(
