Yamaha Tachometer advise

[Rich-ward]

I have recently purchased a Yamaha MT03 with a known Tachometer fault.
Essentially the needle doesn't move, until you apply what i consider to be high revs (can't tell the needle doesn't move) then the needle randomly flutteres.
I have taken the unit apart and believe I have found the root cause, the magnet has light browning on the case adjacent to where the 4 connection pins are located. I would appreviate some advice or confirmation if anyone has had a similar issue.
In addition, can the fault be repaired or will I need to replace the entire unit?
Thanks in advance.

Warranty

And it’s advice, not advise.

If it's a known fault Shirley there's no warranty on it?

Just replace the whole unit for a used one. They can't be that much second hand.

If the bikes still in warranty then everything’s covered I’d have thought.

Thanks for the feedback and wordsmithing!
Bike is second hand (2010), I have looked at a second hand unit and they are about £200. Seemed a little expensive for the sake of a component which should be replaceable.

Shows how little I know, I assumed it’d be one of those new 300cc bikes, not a 660cc bike that’s been around for a decade. Why’s it not an MT-06?

The bad news is that parts break on bikes, especially the ones at the more budget end. The worse news is that if it’s a common fault, then there’s unlikely to be a lot of second hand ones available, so your options are limited. I think it’s a case of live with it, or get a new one.

Yes they are my thoughts too.
Unfortunate as I'm a fairly new rider so handy to see what revs I'm throttling the engine at.
Thanks for the responses.
