It's the maths on Ohms that's the important bit, all in the link mate.

Right I think I've tested it right. I disconnected the plug with the 3 white wires from the rectifier, turned the bike on and left it to idle, switched my multimeter to AC and then inserted the prongs into each of the wires in the connection plug but didnt get a reading from any of them?
I then tested the resistance again and got the same reading of 0.9 from each wire?
That guide said something about testing the multimeter first then deducting the numbers but when I did that the multimeter was reading 1.5 and the wires were only 0.9 (which is half the recommended spec) so that would mean a reading of -0.6 ?‍♂️?‍♂️

Either way I think its getting pretty conclusive that its the stator thats failed?

[Gnasher]

Yep, from what you're saying looks like it shot mate 


If it's the coil pack/assembly the copper coils normally look very dark burnt and can smell the same.  If when you get the rotor assembly off it's not got the inner sleeve on (early type) look at the magnets check for lose damage, you may just want to change it anyway for the later type.

I haven't read the whole of your thread, but if you still have the old rotor in the bike you should really replace that along with the stator.
Motoelectrical do quality pattern parts and for your first purchase you get 10% off so the stator/rotor kit would be just over £300 -

Or I found this on ebay, looks like a reconditioned part as it only has a 6m warranty -

Cheers for the links. I will be replacing the rotor if its original regardless, but that is a decent price for the 2 parts new.
Will know what I'm working with by the end of tomorrow ?

[Dudeofrude]

Well I've found the problem ??

[Dynspud]

Jeepers mate; that's a right mess  :'(
I hope you get it sorted  :thumbup

Well I've just ordered a new rotor and stator from one of the links in this thread (thanks guys) so that should be here in a few days.
There's only 1 or 2 magnets that are actually broken and all of the parts seem to be stuck to the stator so I'm not too concerned about metal in the engine.
I will change the oil and have a route through it with a magnet to be certain but I'm hopeful that it should be simply a case of old out and new in... job done ??

[snapper]

ouch that looks nasty
to be honest I think you've got away lightly that good of been so much worse

[Gnasher]

That's about what you get and what I've seen plus no noise, or hardly any.  The magnets just get pulled in as the bonding fails, so long as they're pulled squarely down on to the coil assembly, the rotor assembly just spins around and produces no charge or very little, the fun starts if one does  :eek

You've had a result mate, in that it's not done any real damaged other than the generator. 

[Dudeofrude]

Yeah i feel like the luckiest guy in the world ??
Nah I know what ya mean, its the best of a bad outcome although not a welcome expense given the current situation ?
Least once it's done I won't have to worry about it again for the life of the bike

[robbo]

Well done Dude, glad you’ve got a result, even if rather painful on your wallet. But hey, things could have been a lot worse. Just enjoy the peace of mind when your bike’s back together, and you’re out giving her some stick. :thumbup

[Fazian]

So glad I did mine as a preventative measure last month, looks like you are a lucky man today  :thumbup

Yep,   I'd give Yamaha a call, state the fact it's well known almost common fault and that they've made an up graded part.  They may just fobb you off but they may not or at the least they may contribute, I've had similar results before.  You've got nothing to lose by trying mate 

[Dudeofrude]

Haha funnily enough I was gonna ask of anyone had any luck getting anything in the ways of compensation out of Yamaha? I would imagine I'd be pissing in the wind but might be worth an email ?

Send the pictures and stress the fact they've up rated that part because of failures, why no recall etc etc.

FFS!  That was a close call.  Hopefully you are not missing any significant bits.
Good to hear you are on your way to getting it sorted.
What years were affected with this?

Well with the Fz1 I believe it affects the 06,07 and 08 but also affects the R1 from 04 and the FZ8 from 10 (i believe) possibly even a few more that shared this engine

[VNA]

Good to know.
Hope yours is up and running again soon Dude.
