Gentlemen,

Spoke to Gary at Custom Rewind. I was looking to find out kind of information he would need to rewind my '09 stator to the '08 specs?

Of course he explained in his Southern accent, the output is a combination of the amount of copper wire on the stator and the intensity of the magnets.

Basically, Gary believes he can come to long term solution with the help of someone who is willing to send in a stator and report back to him the post-rewind results. Gary said it may take 2 or even 3 tries to get it just right.

The first try would be to reverse engineer the '09 stator and dial it back a notch.

He didn't think electrical experience was absolutely necessary and it sounded like someone familiar with an ohmmeter could record the output properly. I will venture to say electrical experience will help.

So is there anyone out there who is willing to be the candidate?

Custom Rewind is in Birmingham, AL although Gary didn't think having the bike in shop would be a huge benefit to the process.

**edit** My stator is functional so I don't want to yank it for a rewind just yet.

PS--He said not to be too hard on the manufacturer and Buell is far from the first to have these stator issues.

Why don't you volunteer? I would gladly do it...but my 2nd stator isn't failed...yet.

Avc--Same boat you are.

also, figured someone from a cold climate who can't ride yet might be a better candidate. I think a problem might be '09s are mostly still in warranty, although there was a person in the other thread who was going to rewind his functional '09 stator for preventative maintenance. Wonder if he would be interested?

Mine is under warranty until October. But in all honesty, if it fails again I will be persuing lemon law. I missed just about all of last riding season due to stator followed by clutch weep. I don't want to miss another!

I might be in for it on my 1125R. My CR is getting a new stator today. My R has not failed yet. I have been stuck with it on the road. I have had a new battery put in it. Not a lot of riding time this winter to see what it is doing. I want to get rid of the harness and do this right. My problem is I do not have the time/money to do the labor. I have the time for the bike to be down. It is going to the dealer for the IC to be looked at and see if it needs replacing. I will ask them if they will do the labor on it and get a price. Can anybody in the NYC area help out on the labor side? This will benefit all of us.

I picture the labor being done at home in the garage as it could take 2-3 times to get it right. It could get pricey to have the dealer do the work.

My CR has been treating me well all winter even with the heated gear, but you can count me in for this if things go south.

Fresno -

I missed something...what do you want done?

I have a stock (working!) stator currently in my CR.
I also have a Custom Rewind stator on the shelf.

I do not have a stator from an 08.

Can this combination of parts help your cause ?

This would be between Custom Rewind and the badwebber who volunteers.

The volunteer would pull his '09 or '10 stator and send to Gary at Custom Rewind, who would then reverse engineer it and take an educated guess at rewinding it to drop the output (probably what he has done on the 1125 rewindings thusfar.)

Gary would ship the stator back to the volunteer, who would then reinstall and take readings to see the results. Depending on the results, it may be a done deal at that point or the volunteer may have to yank the stator and ship it back to Gary for a tweek. This process will continue until the final product is deemed satisfactory by Gary.

He thinks it *may* take 2-3 repetitions to complete the task, although he may likely hit it the first time.

And as a side note, I am not sure if Gary could get the same results in house if we just somehow got him the '08 rotor/stator and '09 rotor/stator assemblies?

If someone provides a blown stator to start with I would be down as the test mule.

I can't speak for gary, but I did explain to him the fact many bikes will be coming off warranty in the near future and will be looking for a permanent solution to the stator issue. His phone might be blowing up soon. He mentioned he has received 4 Buell-related phone calls this week so I think he knows the potential here.

Again, I can't speak for the man but usually in this situation the volunteer isn't charged. The regular charge is $140.

When he (Gary) and I talked about the same thing for me...lowering the output/heat a little he said he would look into it.

There was no note with the stator when I got it back...so I was unsure what if anything he may have done different to mine.
I gave him the Buell output spec's. in a note with my stator.

I figured I'd just give what he gave me a try and go from there as far as the output and resultant heat.

And like was said, he does make it a lot more difficult for heat damage by first insulating the stator segments....then rewinding. Who know's, that in itself may be enough.

Is the output the problem or is it a manufacturing problem. It seems like superimposing the '08 spec might be totally unnecessary.

If we knew that the '08 and '09 stators were identical except in output, the output being the problem seems like a logical conclusion but from what I understand, they are not the same.

It seems like going to the '08 output is jumping to conclusions and introducing additional variables.

Stress test: Ideally the donor should be a person that racks up a lot of urban miles. Someone from the south where summer temperatures are typically higher.

BTW, my previous comments were not in any way intended to detract from the project at hand and I am thrilled that this is happening. I just had a question about it.

If I weren't in Oakland and was still in Phoenix, I'd definitely offer up my stator. Unfortunately, I am here were it is colder and the bike is my only transport.

I'm going to try the Harley "upgraded" stator and see if it works. Other than that Gary is "The Man" for correcting this problem. I spoke to him earlier this week and I suspect the reason he is getting so many calls is because of my initial phone call and posts. Gary is a class act.

plan to call and tear mine off in the next week i would test a reduced power if he can shorten down time between trials.
I am a master certified auto tech and have a fluke meter + snapon charing system anlizer.
I have a few(4-5) weeks before the dragon ride to get my bike together.
So i plan to call him monday.When i do i'll ask about testing for him or just get his basic rewire and see how it works.
Sucks being i am under warntey but 90% of my miles are 12 hours from home i don't want my bike to go down while i am in Nc

Guys, I'm curious what the belief is... I've read mixed opinions on what the actual cause of the issue is with the 1125's stator. Some are of the opinion that simply lowering the output of this stator is enough to prevent problems, others are of the opinion that there was a manufacturing issue.. (Poor material insulating the windings of the stator) which caused the stators to short. Has anyone looked at temperature differences between an 08 and and 09 or 10? Personally, my opinion is that if custom rewind has a better epoxy for rewinding the stators, that stands up to the heat, doesn't it make sense to keep the same output? I want that extra juice so I can run heat in the winter, etc. Just a thought. I am an electronic design engineer by trade, I design telecom equipment, power isn't my specialty, but certainly not out of my league with a little brush up. I'd be glad to lend a hand once my bike is out of warranty and the stator fails again. I haven't looked at the nitty gritty details of this yet, but just looking at things from a big picture view, I would be surprised if the wattage increase alone would be enough to cause these issues. It wouldn't be difficult to figure out based on the wire size and the wattage output of before and after what the temperature increase of the wire would be going from 08 to 09.

Youk, I am in complete agreement. So far, there isn't anything that leads me to believe the output is the problem.

My CR is in the shop right now awaiting a new stator from HD. However, I called this week and asked about getting the old one (I had thoughts of getting it rewound myself), but was told I couldn't have it since back.

Cowboytutt, is there really a redesigned stator from HD?

My dealer spoke to the highest ranking Buell Service Tech and that's what they said. The part number does not seem to be different though. Harley parts usually have a AM suffix if they change it, but Buell part numbers are a completely different animal. All of the small parts they ordered for me have the AM suffix. Hopefully it is accurate information. But if your out of warrenty then Gary is the man to see. -Tutt

After finding out what Buell got for a stator, we found a small company from the frozen north (Canada) who rewinds these things. They do a lot of snowmobiles which have Rotax engines and their price was very good. They have a process that let's US customers fill out certain paperwork to save paying duty on the way back. I can't remember exactly but it was right $200 US or about 25% of our local buell dealer. I will have to hunt for the invoice and post their name and address. Our customer was happy with no charging issues for over a year now.

Is your customer with the rewind using the harness?

Not sure, but I will check. He picked up the bike after it was crashed and had a hole punched in the case and I think the stator and harness were both damaged. The shop that rewind it said it looked like a couple of others they had seen on Rotax units. I will do a follow up post with the details, but my discussion with him the other day again confirmed No Charging Issues.

doesn't it make sense to keep the same output?

well, most owners don't run accessories so the '08 output would be acceptable. But your point is valid.

I also believe the lower output of the 08s was to maximize the horsepower of the first year model, which is also desirable for most owners.

Perhaps two stator fixes--one close to the 08 wattage for those who don't run accessories and want to minimize the drag on the motor and two a more robust electrical output for those who like to add farkles?

Boy, it would be great to get both the 08 and 09 stator/rotor assemblies in front of Gary. I bet in a few minutes the man could tell us exactly the problem and hence a solution(s)....

does anyone have pictures of the '08 rotor/stator and '09 rotor/stator?

Just wondering how different they really are...

They are quite different.

08-18 pole, machine wound, looks like other Rotax Stators.
09-12 pole, hand wound, looks more like a HD stator. The 09 stator is physically larger.

The 08 part looks to be of higher quality. I wonder...
