Speedo Gremlins

[West Cork Paul]

There’s an opportunity to buy a 749S, yellow, Mono, at a knock down price of £3k because it has a ‘few electrical issues’. The main one of which (the others are really minor) is the fact the speedo reading is erratic or non-existent, ie it either jumps around or reads 0.

Allegedly the speed sensor (first obvious culprit) has been changed but the issue persists, leading the owner to believe it could be an issue with the dash display circuitry.

I know the dash/instrument unit, ecu and keys are all coded to each other so it’s not as simple as changing the dash out as all 3 units need to be kept in sync or else there’ll be issues with the immobiliser.

Has anyone with a 749/999 had a similar issue? What’s the collective mind/thoughts on this?

TIA

Useful link that Mark, thank you.

Thanks. I suspect it’s a wiring issue in the loom rather than an issue on the pcb within the dash but you never know and that’s the risk here.

Have you tried the fuses? Taking them out and checking/cleaning them?

I don’t have the bike, just considering buying it, rectifying the issue and flipping it

Offer them a Barry for it

I’m thinking along those lines, although his ad says no offers I reckon he’ll be hard pushed to sell it over here as is unless someone buys it as a track bike.

My worry would be that the owner has already done the same basic checks I’d be thinking of ,
priced the parts up and thought stuff that

Never heard of them Ron, but thanks for the pointer, although the map shows them to be in Limerick City (despite saying Cork in Vymaps) and the linked FB page is Facebook.com/westcorkwomensmotorcyclists which is no longer a valid page.

Very true but I won’t know until I go and have a look.

As it happens @chrisw has a 749/999 clock set that, provided I give him the red key, he can reprogram so matches the key and ecu.

Come over a bit Saville there Paul..."as it happens, now then now then, Chris has fixed it for me..."

The dash is programmed on the bike with the red key. Instructions are in the 749/999 Service Manual.

So I’d just need to get the dash off you, install it and then run through the programming sequence?
