The sensor seems to be a magnet and what it appeared to sense a metal disc with four splines on it. So...

What have others done? Looking for mounting inspiration and tech details!

Cheers

Skip the disc, make a bracket to mount the sensor close (i.e. very close) to the 4 bolt heads that will connect your prpshaft to the prop adaptor flange. Worked for me anyway...

So I guess it dosent matter that the four bolts are not set equally?

no but the number of bolts matters - in your case this matches the slots in the disc.

Didn't make any difference to mine...

K guys, thanks for that.

One last question. That area of the car, (ie the prop flange adapter), is pretty crowded so I am thinking of moving the speed sensor down the tunnel and mount it somewhere around the center bearing. If I do this then obviously those aforementioned bolts aint gonna be around so what can I substitute them with? Am thinking of gluing four small neodymium magnets to the prop. Would this work or should I use something non magnetic?

see my U2U

They don't need to be magnetic, they just need to be able to attract magnets, so iron will do. I had the same space issue at the front so I placed mine on the driveshafts (added advantage that you'll have less revolutions so less probability to imbalance). Just welded some pieces of iron to the boltholders. It's a GSXR1000, same system as GSXR13000. Work fine






more info on the www below.

two magnets on prop near sprocket adapter ( easy to get to ) gets to within 1mph acciuracy with speedo healer up to 100mph
