Should we all carry a spare Hall sensor

[gel9001]

Wow it seems like this can be a deal breaker, for those of us who take long trips if one of these go out and there isn't a bmw dealer nearby, that could be a problem. What do you think should we carry a spare, are they hard to install?

thanks,

I don't know the frequency of failure of the Hall sensor but the replacement cost from BMW is kinda pricey. Did a search and found this link. A seemingly exact replacement from Honeywell is pretty reasonable. Not sure how easy it how easy it would be to make the change on the side of the road though.

My bike came aith a faulty hall sensor. The dealer finally reaplced it around 1000 miles and it's been working fine since. I just turned over 61,000 miles, and hopefully it won't fail.

A good question but an unrealistic option on the side of the road, firstly they are riveted on.
I couldnt imagine carrying the bracket assy with two hall sensors plus wiring loom, just in case...
the cost is around $450 AUD so expensive if you never need it. The bike needs to be retimed as well

If the Hall sensor goes, and they do go, the answer is a tow truck, sorry.

Where were you guys three years ago
That HALL SENSOR could be a deal breaker, but for me it was a BANK breaker.
I was riding in the storm on the way to the Rally in Vermont. Stopped to fix a flat tire.
I still don't know what did the damage to the HALL sensor, the rain or the AirMan compressor.
Two days in the motel HELL and 200 miles tow to one of the Southern BMW dealership, the size of my kitchen, and my kitchen is small, even my wife does not go there.
Sure enough, the dealer did not have needed HALL SENSOR in stock. I had to beg them to take it of the used RT and I paid for the labor for both bikes plus for the HALL sensor. I think that after 2002 BMW improved Hall sensor for our bikes. I do see some kind of diodes added to the wiring of the HALL SENSOR. The price I paid for the HALL SENSOR, I could have had...Ah... never mind
I learned my lesson and would never leave home without it.
For $250.00 it is not worth the risk on the long trips.

Good Luck.

Carry a spare??
I don't think so.
If/when it does happen, I'll rely on my cellphone, my wife and my truck to get it back home. Besides, the majority of my riding is just under an hour away.
Most important, I avoid the conditions that could damage the Hall sensor and many other costly/vital bike parts like:
--Overheating the engine (LCD temp gauge shows crankcase temp).
--Riding in heavy rain thru standing water puddles (sudden thermal shock and corrosive water damage).
--Avoid electrical arcing (like loose battery terminals, improper jump starts or accidental service time short circuits).

If you do carry a spare, there should be diagnostic tests to confirm Hall sensor failure before the lengthy R&R is begun. Every diagnostic mechanic's rule #1 is always make the easy shots first. The link that towerworker provided details the ordered steps you should take before replacing the Hall sensor.
