cylinders appear to be missing

Hi
Due to a bizarre series of swaps I have acquired a k100, B reg. Are there any known problems with them, any one got one and can tell me what to look for?.
Cheers.

Steptoes the man for the K100 lowdown. I've had a few and they have all been ok. The tick overs can be a pain, there's an air bypass screw under a plastic cover on the airbox that needs to be adjusted once the throttle bodies have been balanced. The early K100 had a mechanical airflow meter that can screw up with age. The bypass screws on each throttle body have usually been tinkered with as well, this can cause problems. If you can live with the strange dated handling they make a great commuter.

The early ones had a steel seat base that rusted through.

Speedo circuit boards connectors play up resulting in a dead speedo.

The fan thermostats fail causing overheating. You get a warning light on the dash when this happens.

Mainstands wear badly

I had an K75 alternator fall apart in France. The French Auto electrician fixed it with bearings and parts from a Fiat

I'm sure you will get some more feedback.

B reg - means the electrical connector is at the front righthand side of the fuel tank. It's just a push fit, and they fall out, causing an instant engine stoppage. Make sure it's goodfit.

Hope the engine is quiet when it's started from cold

check the rear drive shaft/bevel splines for wear - if they're worn, you maybe in for an expensive shock - as BMW no longer supply the early drive shafts (16 toothed splines) so you'll get the later 20 tooth splines shaft. But that also means you'l need a matching bevel with 20 teeth.

Watch the centre stand - it's hollow tube, and breaks.

Spin the cooling fan around by hand - if you can't, it's seized. Which is fairly standard

pre 86 bikes also have the crap seat that has a metalbase that rusts. Tochange to the later seat, you also have to have the matching tailpiece.

You should always try to buy a post 86 model K all the earlier problems are sorted out, due to the customer being used as a guinea pig - in the typical BMW way

Nightmare! Think of all that reliability and performance! Nothing to do at the weekends!

(Been there, got that, and still ride a BM - why?)

Don't I fecking know it!!!!

Picture the scene. I arrive at the Driving Standards Agency in Cardington early one cold December morning, a few hyears ago to take my exam to become an approved bike instructor. I pull up outside the offices, next to another guys bike. I gracefully dismount, and put the bike onto its mainstand in the DSA approved fashion. God, I'm good, methinks,

Then it all goes wrong, as me bike crashes to the ground, away from me, merrily flattening the bike parked next to it. WTF????? think I.

Then I realise that the mainstand picked just that very moment to collapse, as they all do Sir. Thing was, if the nearside leg had broken, there would have been no problem, as the side stand was still down. The fact that the off side leg failed meant that there was no way to save it. ARSE!! Thankfully no one was looking. Mind you, the DSA assessor I asked for help to pick the bike back up was a complete git. He would not help, but told another student to help me. Barsteward!

Fer Gods sake, it could have done it any other time, outside the shops, anywhere but there!!! Still, at least the bike it knocked over was a pile of scrap already And the cheeky bugger of an owner tried to tell me that it had broken his indicator, not realising that I had already checked it, and it was bust well before I got anywhere near it.

A good example of sods law, i think.
