2008 SD990 Intermittent Speedo ??

Postby johnwiz » Thu Jun 25, 2020 6:16 pm

Hi Guys , my problem is an intermittent speedo , just started happening today . Revcounter & all other electrics working but speedo stuck on 0mph then starts working again ..Just wondered if it's a common thing ? My front wheel rim is a bit buckled , would this cause it ? Bike is fitted with a Datatool alarm which I recently switched to "Winter Mode" as it was killing the battery ; I see a cable going to a sensor in the front wheel ...
Is there a workshop manual online ? Any help appreciated , Cheers John

Buckled rim ain't great but shouldn't affect speedo as sensor on lhs fork picks up brake disc fixing bolts to monitor speed - first step, clean face of sensor and disc bolt heads - if that doesn't work, could be faulty sensor, wiring, connectors or, worst case, faulty clocks - workshop repair manual is here viewtopic.php?f=18&t=16897 re location of respective parts and check procedures.

If its simply a case of a sticky speedo needle, clocks are relatively simple to dis- and re-assemble and there are post(s) on here re how to.

The distance from the sensor to the disk bolts should not change if all is well with the axle and wheel bearings. I would follow the sensor wire from the wheel to where it connects and check that all is well there.

Looks like 47 beat me to it.
