Are there two different types of stator design for 09 bikes ? I sent my stator for rewind and received back a different one,it has 12 poles the same but the outside of the pole is square,(looking at the pole from side)whereas my one had bits that stick out like ones i see in other pics.(if you see what I mean) I am waiting for reply from winder where mine has gone,but wonder if this is even a 1125 stator. my stator was dated 23/08 and the other is dated 49/08.

A photo of your new stator would certainly help.

I'm not aware of more than one stator core design for 09. I think you mean the end of each pole isn't wider than the shaft. As you can see in these two stock photos, the end of each pole is wider than the shaft where the wire is wound. This serves to focus the magnetic flux and retain the windings.



The plastic flange extensions at the end of the poles certainly aren't required. Just make sure the OD of the stator is less than, but close to, the ID of the rotor. Then you can reinstall, check for binding, check with a multimeter on AC at idle and 3000rpm, connect to voltage regulator, etc.

Hi,yes thats right the little bits aprox 5mm square that stick out are not there. The rewinders have now found my stator and are rewinding now so I can swop back. I am not sure how to send pics here,if I can work it out I will show the stator I received.
Your info on rewinding is great,thanks. If mine fails again I will prob try a rewind myself.
The rewind people I am using in UK say they use a size larger wire 1.6mm (1.5mm) and put a few less turns,however they wont give any warrenty. my original has lasted 9000 miles mainly without HD harness mod I disconected after a short time when the relay failed.

Think I managed to upload photo !

It looks fine to me, except I don't see any sort of epoxy coating on the windings. The coating may not be required, but it would help protect against vibration and it would help conduct heat between layers.

It looks like no epoxy,but there is a thin layer of a clear resin,(hard to see in pic)I asked about this and was told it dissipates heat better with minimum coating. Thanks for your comments.

Glad they found your original & got it back to you. Im trying to decide what stator to put in my 1125 so I called up Ricks Motorsport and got to talk to Rick He told me the Buell stators that are made in Taiwan are made on a state of the art Japanese auto winding machine. They use the same insulated high temp wire that Rick used to wind here in the States. I asked about the uncovered wire on the machine wound stator and he explained it to me this way after the stator is wound, it is electrostatically coated with a dry powder and then current is passed through the windings to heat them. This melts the powder coat and encapsulates the winds. The powder coat job is to hold the windings together. The wire is already double insulated.

I asked if he would do a hand wound stator here in the States and he said yes, but it would cost more as it is more labor intensive than the machine wound. And he would only do it on a brand new laminated stack because the plates on the old stator have a tendency to warp and bend. So, now I have to decide if I want to send $225 for the machine wound or $299.95 for the one made here in the US. He said the warranty is the same on both: 1 year.
