Replace damaged stator/ Upgrade RMstator Yamaha R1 2008 RN19 4C8

[@tkaxxdavexx6874]

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!

[@ciprianandronescu3339]

Thank you for given my channel a chance. Agee with you about OEM parts definitely better. I couldn’t get the OEM so i had to go for next one after and same like you had a bit of looking and all guys recommended the RM stator. Thanks one more time

[@kokobeatz7222]

Yup. Put an rm stator in my fz1 last week just for preventative maintenance. Seen a ton of people using them. Well the bearing races are thinner. And I believe it took out my bearings.

The bearing races surfaces on my rm stator were marginally thinner than the stock ones. I believe the rm stator caused my bearings to fail. I’ll be posting a video about it soon.

@@kokobeatz7222guten Tag zwar schon eine ganze Weile her aber kann es sein dass das heulende Geräusch normal ist, ich habe das auch seitdem ich den neuen überarbeiteten Original Yamaha Rotor verbaut habe. Andere haben dieses heulen oder hohe Pfeifen auch schon geschrieben. War bei dir etwas nicht in Ordnung etwas defekt oder ist das Geräusch vom neuen Rotor einfach ein anderes?

Thanks bro, great video

Thank you for your video! How is that stator and rotor holding up? I just ordered one is it a good thing to do and quality piece? 09 FZ1 . Thank you for your time.

[@ciprianandronescu3339]

Thanks for watching and appreciation. I have done 2 .5 k miles since that video and just took it apart again to check and also do a leak on the starter motor. Everthing looks as i fitted yeasterday, and also charging 14,3 v in race mode and 13 v in iddle. So go ahead and do it. RM all the way. Also did bearings now but no problem with the old ones . I will have some more content about R1 soon.

Hello there, how is the RM stator holding up? I have to change mine. OE cost twice more and Rick's motor stator $166 compare to $320 OE. RM only $135. Should I use RM for my 2006 Yamaha vster 650? Thank you for sharing this video

is the bike still running good? how many times have you rode the bike since changing the bearings? could you do another short video of how the bike runs now?

[@ciprianandronescu3339]

Hi mate, yes the bike runs perfectly since i had replaced stator and it’s charging 14, v all the time. I had been riding only twice because of great brithish weather. There is a short video on my channel but I didn’t took video of the rides because I didn’t had my go pro with me .

[@bradstreeservicellc2894]

Thanks buddy, mine did the same thing, i dropped the oil pan, but im a little concerned maybe i should rebuild it...

[@Gezenguz123]

how work your's generator whitout magnet? :D will you looking where is yours general problem? how did it fail?

[@ciprianandronescu3339]

It still got magnets on the flywheel but they are behind that sleeve. Upgraded flywheel

[@timothyharper5673]

The oil and heat breaks the proxy down over time.look at the new upgraded stator which he's used with one solid magnet

[@TommyLidal]

nice video, but you didn't change the bearings ? hope it works out for you.

[@ciprianandronescu3339]

Those bearings are sitting in oil, they are not sealed unit so we can say the grease wears out. There are bearings in gearbox how come we don’t need to change those? I’ll do more research and change them if needed.

Do you think oil pan should be taken off and cleaned out is it necessary

[@ciprianandronescu3339]

It depends more on the state of the assembly, rotor &stator , on the how bad it looks damaged. I guess mine happened and damage was minimal as you can see kinda everything stayed inside the flywheel. Best yes oil pan taken out for your piece of mind but i think new oil mixed with a can of engine flush and drain and then new oil and filter should do the job, also check the old oil through a cloth for pieces.

[@timothyharper5673]

Apparently after 2008 the stator were much better.did you put a upgraded back in with a solid magnet or did you go for a later stator with the 16 magnets

[@timothyharper5673]

I see you used a up graded stator sorry

[@ghuether0]

Hey I put the washer and spacer on the flywheel gear before I insert it back into the bearing but there was no click sound, I can’t get the spacer to fully press down onto the washer, there’s a tiny space between..any suggestions

[@ciprianandronescu3339]

I don’t think i heard that sound either. Aslong that you got them back in same order and that spacer with baveld edge facing correctly I should be fine. Check the paperwork and schematics. You can find it on forums

[@TALEX-07]

Hello there, Do you know by any chance if on a 2015 model FZ8 is this problem with the flywheel in case? Thanks! 😊

[@ciprianandronescu3339]

Hi, i’m not sure, sorry.

[@carpandrei8008]

The fz1,fz8 and r1 have the same problem

[@timothyharper5673]

Think I read something about they were better stator after 08.there a upgraded stator with a solid magnet inside.maybe its worth changing

[@GurillaRon]

What were the symptoms of your stator going bad?

[@ciprianandronescu3339]

Subscribe 4 new exciting videos. So easy just to ask stuff but so hard to do this kind of vid. Also got other stuff about R1 on my channel. If you already subs i do apologise. Now back to you.- not so long before i had the issue with stator i had myself fitted a voltage meter because i knew the problems of this model. When it was ok stator was putting out 14.3 v , one day after a while went out for ride and it dropped from 14. to 12.something volts and very quickly went to 9v . And dead. It had to be failed stator and thsnks to my vastly and superior knowledge I didn’t try to jumpstart or push it or do anything else because it’s then when pieces of stator falls inside the crank case. Hence all the gone engines. Got a van , took it home , took everything out and as you can see in video, it was busted but it stayed in the flywheel. Enjoy.

Salutare, am acelasi model de motocicleta si a inceput recent sa se auda un suierat care creste in intensitate odata cu acceleratia si pare sa provina din zona la care lucrezi tu in video. A avut si la tine zgomotul respectiv inainte sa schimbi rotorul?

[@ciprianandronescu3339]

[@ciprianandronescu3339]

Nu te mai da cu motorul pana nu schimbi statorul si rotorul ca risti sa se dezintegreze si automat distrugi motorul daca bucatele ajung in baia de ulei.

Would you go with rmstator again?

[@ciprianandronescu3339]

No issues since fitted that on the bike. Also for the sake of few pounds for a new gasket you can take it off after 2 or 3k miles and inspect and a voltage display will also help alot keeping an eye on , if it’s always 14.something volts you know everything it’s ok.

[@ciprianandronescu3339]

It’s a common fault of R1’s engines before 2009 big bang. The rotors flywheel has all magnets xposed and after so many miles they go loose and starts grinding and disintegrate the stator

[@Anatatto]

@@ciprianandronescu3339 High rpm may be one of the problem's? I have read the rotor double the rotation of the crank.. You dont remove oil pan to inspect contamination?
