Speedo Problem - GSXR front end. - SV650.org

DarrenSV650S · 09-04-10, 06:29 PM

I've got a gsxr front end with magnets mounted on the discs to run the speedo. As shown here --> http://www.gregoryli.com/search/label/DIY

Since I fitted new discs the speedo reading has been jumping around all over the place. It showed 170mph the other day

. It always seems to be over-reading but never settles, even at constant revs.

I've checked the magnets and they are all the correct way round so that they are attracted to the sensor. And I have checked and re-soldered the wiring connections.

Is there anything else I could check or is the sensor just knackered? It was fine last year, but on it's first run this year (after winter hibernation and new discs) it was wonky.

Try a bit more gap between sensor and discs, it might be picking up the disc rivets.

yea like yc said the sensor is probably picking up the rivets, mine did the same till i spaced it out more

Cool I'll try that tomorrow

Sorted

I must have forgot to put the spacer washers back in when I refitted it. All working fine now

Sorry to side-track your thread, but where did you buy the magnets from given the link on that blog is for an american website?
(I've found a place for the sensor (here) but have no idea where to source the magnets and magnet holders from!

I got mine from an American site. They shipped them no problem
