Yamaha should replace these AND clean the chunks of magnets out of the oil pan for free(if it exploded like mine did) no matter the mileage or age of the bike.

Oh and if you do not put the updated rotor in there your going to end up with issues when those exposed magnets go everywhere. The new updated part has those magnets covered due to so many coming apart.

Did you get this going right? My thoughts are someone had this thing together missing a spacer or something of that nature. My rotor comes right out with the cover if your not careful.

Did you try putting the bike in 2nd gear (not running obviously) and try to push the back wheel back and forth as you try to remove the roter? Sprocket tooth to tooth seems pretty tight when I replaced mine.

Looking to buy a 2008 Yamaha R1 flywheel and magneto. Let me know

I just gave mine a wiggle up down left right up down left right hahha and it needed a light tap to go in also. Just very tight fit due to heat expansion ect.

I'm hoping you might have some insight on it. How do you get the stator plugs out of the air box under the air filter? Really hoping you might know, because I haven't been able to find any info on this anywhere.

Hello so I am having similar problem to yours the starter well it’s been by the motorcycle wouldn’t the engine one and spin I have changed the starter motor and it’s the same thing with the new one is that was you problem as well .? 😭

Thank you for posting this! I was in the same situation with my 2006 FZ1. The previous owner replaced the original magnet-recalled rotor with a new rotor. But for some reason the rotor shaft had to be pressed into the rear bearing, I think. This made removing it 10x harder than yours. So for the next person struggling with this, consider the following. Make a loop in the strap and twist the strap like a tourniquet to keep it on the rotor longer, and then add a handle/bar where you can slam the strap outward with a running start. This is better than just pulling due to the sharp jerking action it supplies. If this does not work, make a similar rig to the strap but with a steel cable in a 3 ft diameter loop. Then after attaching, slam/hammer some very heavy steel bar away from the center towards the cable. A bonus is that the steel cable stay on much longer and lasts much longer than the strap. Eventually this worked and freed the rotor.

Such a dumb design by Yamaha not to just have a "normal" flywheel like pretty much ALL other motorcycles. Talk about over-engineering of a simple item on a motorcycle engine.

What was the cause of this in the end??

I like your idea here, using your thumb to hold the rotor up while tugging was very smart of ya. Trust me most would not have thought of that.

I see you have the old-style generator rotor. The magnets fall out of those about every 40,000 miles. It has happened to me 3 times now. :-( The new part number is 2SH-81540-00 and that has a metal ring to hold the magnets in. Make sure you don't lose the collar (5VY-11445-00) from the back. It likes to drop off and it is possible to forget that it should be there, with rather bad consequences for the gears and starter clutch. (it can fall down into the sump past the crank). I made a metal puller to pull my rotor out. Your way is simpler. (first picture here: photos.app.goo.gl/AzKzGSgcnnsFfJWA8 )

Why change the whole case?? That bearing can be pulled out of there
