Cheers for the tip. I'll take a look when I get a mo. Sidetracked looking after a mate who's ran out of road on his KTM at the moment. If anyone needs any blackberries I've got a fair few in amongst plastics and handlebars of a KTM

Stator slapped backed on the bike, only 1 or 2 AC volts showing across all of the phases. Multimeter tested against another running bike stator just to rule that out as an issue. Looks as if stator is toast. My guess is that it was down to just one phase when I bought it and that's why the clock backlights flickered and now the last phase has burnt out. I've not looked at the back of my stator as I didn't pry it off the sealant holding it in the engine case. Pic attached shows it installed in case and rotor, what you reckon? It's a bit crusty in one part for sure.

My smoke issue seems to be the breather. I think that may have blown off the bottom of the air box. Certainly blows a bit.

West country rewinds have quoted me £141 for a rewind and they sell the rmstat series r/r for £126. Sounds like the way to go. WCR were very helpful btw, certainly well versed on the 1125. Is it worth doing the hildstrom rotor mod?

yes it needs rewinding

Is it worth doing the hildstrom mod or getting the updated oil spraying rotor while in there? Has anyone just run a new stator with series rectifier and had lasting success?

Anyone willing to rent out a locking tool or perhaps let me borrow one?

You MUST have the oil jet drilled into the rotor or the stator will fail again.

What about the Hildstrom rotor mod? Any suggestions for places where either can be done in the UK? Twin motorcycles is an expensive option. £70 just to get the locking tool here let alone reworking my existing rotor.

Several months later...

The original rotor has been drilled as per hildstrom's method. Done on a CNC miller with indexed rotary table so done very accurately. Also, hole countersunk to create funnel effect to further increase air flow.

West country rewinds did the rewind on my stator. They also supplied a RMStator series rectifier (RMS022-106799). Everything fitted, initial testing went well. Idle charging voltage in the low 14s.

On a 15mi test run though, voltage as recorded on dash screen around 15, peaking at 15.3. Occasionally would drop to low 13s but majority of time at 15+.. The r/r became too hot to touch. Previous experience with FH Shindengen mosfet rectifiers I was expecting barely any heat, especially as this series r/r is supposed to run cooler than MOSFET shunt. At standstill, with multimeter I get 15 revving around 5k.

Any experience with this r/r on the 1125? It's going back to WCR for inspection. As a test, I put an FH012AA to check output voltage, max indicated by multimeter at 6k was 14.2v.
