hello guys

ok after fixing my ecu problem...........i know have another one ;D

my bike isnt reading any speed or clocking its miles

talking to jd we have narrowed it down to the speed sensor itself.

checked all wiring/plugs all good.

i removed the front sprocket cover along with the speed sensor.

the sensor seems to have a deep scratch on it u can see a copper colour metal in the scratch.....

would this afffect the sensors operation?

also whilst there i checked the general sprocket area and came across something a little worrying

the main front sprocket nut moves. i can rotate the nut 1/4 each way.....there is a retaining nut also on the shaft , now i am assuming that main nut should not move what so ever.

does anyone know how the speed sensor picks up its signal ?

as for the sprocket nut.....i think its a 36mm can i just tighten it up and refit retaining nut?

cheers

Dan
