Firstly, thank you for this "how to" video. I live in Canada and have a 2007 R1, I decided to proactively change the rotor even though mine looked fine at 22k. I didn't see the need to replace the stator so just did the rotor. I had 3 options, $950.Cnd for OEM, or $250 for the RM or Kimpex (China Made) replacement. I called RM Stator first but they were unfortunately resistant to answer my questions, I found their customer service poor. I ordered a Kimpex brand one which looked exactly the same as RM Stator's. The rotor looked decent but had improper machine tolerances, the spacer didn't fit over the shaft - some people apparently sand it down but I didn't feel comfortable doing this, nor should you need to if machined properly. Additionally, it fit too loosely when seated in the bearing. Returned for OEM. BTW the OEM has updated this part and it does look slightly different than these Chinese knock offs. In a high HP, high RPM engine, I'd buy Japan made OEM... just my opinion. Good luck & stay safe!
Also my chain just snapped on my bike a few days ago. What size chain do you use. The bike I purchased came with a 47 tooth in the rear 16 tooth sprocket in the front and they 520 122 link d.i.d chain. From what I gathered online the bike actually comes with a 530 chain so I'm wondering do I have to go back to that chain I'm new to this FZ1 I'm still learning and nobody's talking about what chain they have on the bike everyone has went to a 520 conversion kit but it's for racing and they say is not good for two-up riding
Yes i would mate. I have heard so many stories about them and Yamaha didn't improve the rotor till 2015 . but i have two FZ1s and both rotors failed one at 56000km and the last one went at just over 11000km. so my experience is not a matter of if it will fail but when.
I have two FZ1s a 2006 and a 2008 both rotors failed one at 56000km and the last one went at just over 11000km. so my experience is not a matter of if it will fail but when it will.
@@photographyrides7913 11k kilometers? Man thats low. The 56k sounds average as thats what I have read usually when it fails. My 06 has 4300 miles on it(6920 km) And I have the part ordered already. Thanks for answering!
@@photographyrides7913 Replaced it last night. The magnets were already looking edged and I can see very small bits on the rotor assembly. Man I caught it on time 😳
Thanks for you video! Did you hear any rattling noises? My FZ has 28k km, I also went for a ride and the engine died and my battery dried up. I recharged the battery and it seemed the bike was back on track, but I test drive it and soon the engine died again. I recharged the battery again and started up the engine, but this time a rattling noise started . I Turned off the engine . I suspect the rotor failed.
yes mate its not worth the risk on how much damage it can do.9000 km or 90000 km its not a matter of if it will happen but when!. and The result of this malfunction is without any warning sign, destroying in most cases both the stator and the rotor. Yamaha, dealt with the problem by making a new and improved rotor in 2014
@@photographyrides7913 Thank You very much for Your answer. I called the main Yamaha dealer here in Switzerland and asked him if the problem is known and he was very surprised and said, he has never heard about it.
Thanks for the video, first I've seen that shows the damage caused when the magnets break free from the rotor. You're probably lucky none of the magnets didn't end up in the rest of the engine - were they all stuck to the stator? I've got a 08 FZ1s, 60k km, you've tipped me into checking and replacing the rotor if necessary ASAP, not comfortable having that potential hand grenade spinning around in there 😅
Yeah mate it's a good idea to replace it it's happened to me twice the 1st time on my 2006 FZ1 at 63k. The 2ed my 2008 at 23k so in my experiences it's not it could happen but when it will 👍
@@photographyrides7913 as luck would have it, the very next ride after my last comment the bike shat itself on the freeway, check engine light came on (error code 46), then headlights cut out and I pulled over. After having to transport it back home checked my generator rotor and it was a magnet soup like yours. Check and replace the rotor people, don't end up stranded like me!
@@photographyrides7913 just ordered the part and a gasket from RM stator about 190 for both after tax getting it on.....monday.....😭😭😭😭 but oh well I'll update you when I install it hopefully it comes sooner like tomorrow or at least Sunday lol

So happy I swapped out my generator on my ‘07 FZ1 at 22k. Saw and heard too many horror stories.
What sounds did you here?
@@alchemist3724 you dont hear any sounds till the magnet lets go and then it explodes. He means he heard a lot of stories.

The fz1 stock sprockets are 17t front , 45t rear and 520 122 link chain i run the 16front 47rear with 520 stock chain
Looking to buy a 2008 Yamaha R1 flywheel and magneto. Let me know
I have got a 2014 model do you think I still need to change it ?

@@photographyrides7913 could you send me a link so I can purchase the rotor
How many miles did it have when it failed?

No mate after the battery died I suspect the rotor failed. sounds like you have the same problem
Anyone have a link to purchase new rotor plz, 2008 fz1n 19k miles and going fine but would be good to have a link to purchase

@@photographyrides7913 sound man 👍
WTF were Yamaha thinking when they made the biggest bollox of an engine design.
Would You recommend a change on a FZ1 Fazer 2012? Or is this problem only for the early models of the FZ1?

@@MyTiger900 any updates did you change it out? Imo if the magnets aren't exposed you shouldn't need to change it.
Bravo! I've never seen anyone work on their bike with their bare feet! LOL
same thing happened to my 2010 and it F@$%et my stater also

It is really necesary to get the updated Yamaha original part. Or can i get an aftermarket. Original costs 550€ and aftermarket is 200€
yeah mate go for it nothing wrong with aftermarket witch this one th-cam.com/video/J1JLEPXBZ-Qg/w-d-xo.htmlo
Literally just removed the flywheel on my 06 r1 the magnets were obliterated into pieces I hope nothing got inside my engine please God 😂
dam hope everything turns out all good Mate

A little to late for me mine exploded :)
