Noisy speed sensor?? - Geedog - 26-03-18
Can anyone shed any light on an issue..?
At around 35-40 mph I’m getting a whistling sound from the front end of my 2003 FZS600, I thought it might be something stuck in the fairing so investigated that and came up with nothing.
I took off the brake calipers and spun the wheel with drill and found the sound coming from it appeared to be the sensor area or bearings.
Took off the wheel and the bearings were very stiff, unable to turn with fingers. Started process of removing them and once slightly loosened off the spacer bar have freed up considerably so not sure its anything to do with them...
The moving part of the speed sensor is a little slack - is there supposed to be any movement..? ( other than spinning..!)
Any help appreciated

As long as the sensor is seated properly, preferably with a good dollop of grease, then it's unlikely that it will make any noise.
If the sensor isn't positioned properly it will simply break and not work.
I'd hazard a guess if the sensor is well greased up it would more than likely be the wheel bearings causing the noise.

Make sure your caliper pad pins are cleaned up too in case the pads aren't sliding on them properly.

I fitted a new sensor and didn't put enough grease in. It made exactly the whine /whistling sound you seem to have. It needed a huge dollop of grease to shut it up.

Hopefully it is as simple as that, just second nature to me me now to grease the hell out of that area when it's apart.
Bearings still don't sound too ideal but always try the cheapest option first though.

is there any notchy feel to the bearings,if there is its only a few quid to get them replaced (2 less pints this weekend)
even cheaper if you have a bearings supplier nearby that you can take the old ones to
dont hold me too this but i think the fronts are od40 id17 w12 so a skf 6203 2RSH is a possibility and should only cost a few quid if you have a local supplier
Re: Noisy speed sensor?? - Disorderlypunk - 26-03-18
scratch that - the bearing size is right but not 100% on that exact bearing number it might be a little too lightweight for the job
but a bearing supplier would be able to tell you for certain
Re: Noisy speed sensor?? - darrsi - 27-03-18
Just buy sealed bearings!
Re: Noisy speed sensor?? - Disorderlypunk - 27-03-18
thats what 6203 2RSH are they are sealed and im sure they are fine but i dont want someone to go out and buy them before i consult my little book of lost knowledge
(ok its a big book as i keep getting hit in the head and forget stuff)

Forgot to mention, original sensor internal lugs are ceramic and break up with accumulated gunge. If you take the sensor off they will fall apart. Replacement sensor has plastic lugs, and much more robust. Just remember, Grease is the word :-)

bloody hate it when that happens
Re: Noisy speed sensor?? - Geedog - 27-03-18
Thanks all
Ive had a good look at the sensor which appears to be all plastic..thrown a load of grease in and reassembled.
The whining is gone now spinning wheel with a drill, Ill get the brakes back on and take her for a spin....fingers crossed it’s solved..
Re: Noisy speed sensor?? - Geedog - 27-03-18
Update, took her out and up to 50mph with no noises
, will take to work tomoz which will test to the max.Thanks again all
