I've just had it explained to me ...

Don't see why not ... race bikes have racing wiring looms on them... it would a specialist bespoke service tho'

But shirley a racing bike loom (and I don't know) is designed as most things are for racing......high quality/light etc but expected to be replaced every race or two......for a GS in the real world, a 'racing loom' is probably the very last thing you'd want to fit.

Double redundant extra thick wiring and duplicated in-situe plugs is what I'd prefer


Sod the weight......long term reliability and bodgeability is what you need rather than a few kg's saving (max) by going hi-tech thin/light/fragile

I mean racing loom in terms of ... adapt it to suit your needs - get rid of unnecessary guff ...
RickG was interested in a "bulletproof" version of the GS - get rid of guff.

How do you test it without expensive test equipment?

In the case of FPC failure, its obvious enough that you don't need to interrogate the Canbus. If the EWS fault occurs, the RID shows the EWS warning for you.

For true testing, a GS911 device can be used which I paid £230 for, relatively inexpensive for test equipment that can be used across the entire current range of BMW machines and many older models.

This is perfectly true and the GS911 is a wonderful device for fault finding CAN and non Canny bikes with ECU's. I just can't help thinking that without a RID, a FPC (mine coincidentally died today) an EWS or any other acronym loaded electro-lump, I wouldn't actually need to care as I'd have honest to god volts flowing through my wires. If they didn't get to where they were required and the bit on the end didn't glow, whirr, honk or spark, I'd trace the wire back to where it was broken or corroded and fix it by twisting two ends together. If it had gone toes-up the fuse would have gone pop and given me a whole bunch of clues regarding the fault without forking out 230 quid for an admittedly wonderful diagnostic box

I think back to the loom on something like my old XT500. It was so minimal that it must have been less copper intensive than the even the most CAN-lite system a modern engineer could wrap onto to a bike. All I want on a bike is a core system that provides a 100% reliable spark and good lights, the rest is just excess baggage like all the app's on my mobile phone. It's just junk to bolster the spec's on the latest model because it's now technically easy and we're daft enough to lap it up because it's sold as being somehow better than the previous iteration.

I've previously admitted that clever electronics are the only way bikes are going to continue to be allowed on the road. This does require all manner of electronics and sensors, but ditch the value-added gimmickry that simply adds to the number of bits that can attract a problem which can result in a failure to proceed. Then make the core system bullet proof with get-you-home redundancy in the event of a peripheral sensor failure and we won't need to complain so much.

Just another point as it's so simple technically.. wouldn't it be nice if the very clever computer explicitly displayed the fault on the RID? No need whatsoever for a hook-up to interrogate the ECU for the fault code and translate it into english. It could even call BMW-assist or the RAC via bluetooth to you mob' so they are waiting, new electro-lump in hand, at the next junction as you cruise silently to a standstill..

Maybe on the 1250GS.

The racing F1 looms are built using airframe wiring standards with canon connectors and twin helically wound looms, and pre-formed heatshrink boots at strategic stress points.
Done properly you wouldnt be needing any redundancy as it would be bulletproof.
It'd cost a fortune too

I reckon that any weight saving in the wiring loom department is more than compensated for by the increased weight of today's riders

If the lack of easy maintainability in the longer term means that people just buy new bikes more regularly I'm not convinced it's going to save the planet either. I can just imagine that car and bike manufacturers will follow the Microsoft route of not supporting "legacy" products in order to ensure continuous production.

OK, this is where it starts becoming a foreign language.
Have you checked the float chambers in your carbs?

Maybe that's another reason for Canbus: to compensate for increasingly lardy tossers!

OK, in simple terms:

If the immobiliser breaks down, EWS appear in the instrument panel in very big letters. How obvious is that for you?

As for carb float bowls, I've wasted too many hours cleaning carbs on previous machines and used to be especially pissed off with dangerous carb icing in winter etc etc. Thank god for reliable FI systems. If only the fuel pump electrics could be so reliable.

I don't understand it therefore it is evil and must be destroyed.

Actually don't destroy it, just blame everything that goes wrong on it.



Bring on FlexRay that's what I say
