My Sv650 k4 speedo sensor conundrum.

[nerd]

hi guys,
My speedo sensor recently packed up (rota smashed beyond repair)

bought a used one off a 06 - this read the speed x5 what it was.

Asked on here and was told a need an earlier one so a kind orger sold me one from a 03 - now this one doesnt read anything. (however from what i can make out from the broken one this does look like the correct part)

I thought it might be the wiring so put the 06 rota in the 03 wire pod thing and it read x5 again, so i know thats not the problem.

any help would be great as have tried fitting it 3 times with no joy, i cant see what im doing wrong it seems v striaght forward!! lol

cheers

Oh - it definitely was working when I took it off the bike...

[nerd]

yeah its np mate. the wiring defo works. not sure what im doing wrong 2bh lol

[Purity14]

was it definately 5x the speed, like accurately dead on?
or was it 2x the speed and you are exaggerating?

Its important.

[nerd]

Erm 2bh it's prob x3 maybe. I went around the block and it said I was going 60mph and covered 1.4 miles (takes with the 06 one)

[Purity14]

Ok, that isn't accurate enough.
You need a friend or a satnav etc and find out what the multiplier is EXACTLY.

If its as simple as 2x the speed, then just drop a 4 magnet sensor in your front wheel.

I've got an 01 curvy and put a pointy sensor in by accident when mine broke. It read exactly twice as much. Fastest sv ever tbh, 0-150 and beyond was really fast. Lol

Does your graphite sensor thing have a plastic back to it or is it all graphite?

The K3/4 speedo is a 4 pluse sensor (like on the curvys)
K5 onwards is a 8 pluse, the part don't interchange as it does exactly what has happened to you. Was it just the inner piece that was smashed up?
They're about £25 notes on Robinson Foundry or at a Suzuki parts dealer

The K3/4 are a different bike to the later pointys in a few ways (ECU, Motor, electrics to an extent, seats and subframes)

HTH
