Sorry, don't have any experience of the problems you encountered.

Probably there's different batches of components that are worse but my (early) -07 still have the original stator and rectifier/regulator and it passed 85kmiles.

 

I'm not sure how your charging output to batter was and from the stator. Try putting a new Yamaha oem Rectifier/regulator,thats where my money is at, they updated to a new version...plus new oem stator and an oem stator which I highly recommend because its one solid magnet. If its still frying up the stator, gotta bust out the multimeter and check for ground.

 

Hi!
Did you found whats burning stator....I have same sh**t and I cant figure out whats the problem is....

 

Something is going to ground or your reg/rec is bad. Check the reg/rec and if it tests good, start checking your harness.

 

Reg/rec is new (could it broke down after 2k km?) and also check harness (seems ok, no burned wires). Could it be flywheel? Maybe some magnet doesnt work properly?

 

Could be the rotor if it touches the stator.

Reg/rec's fail. If it got hot in 2k miles, it could be bad. If the thermal paste wasn't top notch inside, it could be bad. Anything can happen, assume nothing.

If the harness is good, ohm the relays to ground and see if any have failed. Something is dodgy.

 

I also thought, maybe, rotor touches stator, but NO! Flywheel is new style with protected magnet. There are no signs of attrition om stator I call many places and two guys said, its flywheel (sometimes magnets changing poles and bla,bla, bla...). Today, I ordered new flywheel. Maybe this will solve the problem ( if not, then probably next stop is at Yamaha service). Ok, I will try to measure relays and I hope, reg/rec still works (its expensive gadget😬).

 

You'll get it bud.

 

Did any one ever figure this issue out? I am going through the same thing with an 06 R1. Recently replaced the stator, rectifier and flywheel. All new OEM parts. Rode the bike maybe 3 times. The last time I rode about 140 miles and the stator has failed again.

 

so it seems like there's a bad connection from the rectifier to the battery, but before I tell you to do some 14 gauge wire splicing and soldering if that's the case, what is your charging voltage at idle? it should be at 14v constant.

 

Nope!
I'm thinking about to sell this problem to other...no one has idea where to look and how to solve this

 

Manual says 14.4v at 5,000 rpms.

 

Yes it should be at that range, a healthy charging system with a good flow from the stator(AC) to the regulator/rectifier(converts to DC) to the electronic components and battery, it should read high 14 at idle constantly

 

Wasnt this a common failure part, this is the upgraded part.

 

Yes it is, that is the #1 replacement you' ll have to do the rotor assy, also check your guys rectifier/regulator on your bike because it might be the wrong one or out dated, I found out that this was a big issue with my low charging output. In the picture below the original R/R that came with the bike is the top one that says (FH0 12AA) which is out dated I believe, and the new updated R/R is the bottom one (FH0 20AA) Part number 1D7-81960-01-00. After I got this new R/R replace it fixed my charging issue. Let me know if you guys have the R/R that says FH012AA on your R1 because i'm curious if it came stock.

 

Has anyone find solution , i have same pronlem , stator keep burning up , i checked amps on stator , on idle it draws around 20amp per phase , but from rectifier it goes around 8-10 amps ( few amps on batery ) can anyone measure amps on stator on bike thats ok ?

 

20amps? That'll do it. The wire won't carry 20. I don't even have to rip into my bike to check my amp draw.

You've got something going to ground bud.

 

Yeah i know but there is nothing connected , a soon as i connect rectefier on stator , ( nothing conected on out terminal ) it goes up to 30amps per phase , when i connect out terminal id drops down to sround 20amps , as i go up on throtle over 11-12 000 rpm it goes up to 33 amp per phase , from rectefier to engine and acu around 10 amps , when i disconect rectefier , bike runs normaly on acu , there is no power surge

 

The check the mega ohms on the stator. Not enough varnish me thinks.

Is this an oem stator? Or did I come from Rick's motor sports? Or is it some other stator?

 

I have replaced around 12 of stators , oem , china , rewined .... and everytime same thing , changed 3 types of magnet , same thing , whatever i do there is around 20 amps per phase ..... i have this problem for years , changed ecu , el instalation , everything posibile ... new batery , when it stsrted i could go around few moths until stator burn , as the time goes on the time intervals got smaller , and now as soon as i started it it start to burn

 

You're going to have to take it to somebody. This isn't something I can troubleshoot from my house over the internet unfortunately.

I was going to recommend Rick's stator, but, if you are just burning up stators, that probably ain't gonna cut it.

You've got something going on with the ground circuit. Grab you a bucket, fill it with kitty litter, add some water, throw a copper rod in it, run a wire from the rod to the bike, and check the amp draw on that puppy. If it's high like that, then it's something going to ground. Start unplugging @#$% and see when that excessive amp draw stops.

That's the best I've got for you boss.

 

Have you replaced your R/R?
