    The DTRE CDI for example revs to 10K restricted. Earth the green/black wire and it's full power.

    The late DTR models had a horrendous amount of restrictions on them.

      @goprokid95 I know that... 2004 bike, the crank its diferent, and the stator fits in the engine cover.

      i already try the DTR 2002 stator in a 2006 DTRE CDI unit it works, but no reving mutch.

      i run 35.000km with no problems full stock bike \ all eletrical working since factory.

      i already make som mods on my engine... my bike was one of the first bikes with 200cc kit in portugal. i let the youtube link here

      https://www.youtube.com/watch?v=oPKfwwHDOKQ

      But now i want to put the bike full oem becose the police....

      i have 2 engines, 2 eletrical systems

      1 complete swap from a 89 dtr

      1 complete swap from 2005 DTRE ( thats my blue bike )

      so my problem its the 2005 DTRE Stator burning...

      As i said i try diferent ways to run the 2005 swap ( oem Bike swap )
      the stator is burned like i said. And i try one other stator from 2002 DTR (from other bike)
      I make some adjustments to fit a 2002 stator on 2005 engine, it fits realy fine, the wires i connect color with color and it runs, but dont rev mutch (im thinking provably its out of timing)

      aniway im thinking, maybe the best solution is rewind the oem 2005 stator (Source Coil)
      Do you guys know a place to do it cheaper, or maybe know how many counting turns have the source coil ? tks

        @calum the ignition curve on DTRE changes when you make earth with black\green wire ?

        i already have that done... but honestly i dont feel diference between that...

          @karumaspt I think it's more the fact that the powervalve is retarded after 10k RPM.

          And you're not doing it right then, as it's a massive difference.

          I remember saying the same thing back in the day when I tried it. Then I went from a OEM CDI to a Zeel, which went faulty and back to the OEM and the difference was mad. But unfortunately I snipped back the wire (thinking that I'd never go back to OEM) so had to reearth the wire and it was a big jump.

            @karumaspt only place I know to rewind stator is a UK company. West country windings. Very reasonable prices and they do postal service. Check out their website, westcountrywindings.co.uk (+44)01279731172

              @karumaspt

              There were 3 types of stator, 1988-1997, 1997-200? Then the dtre ones. Iโ€™m guessing youโ€™re the later re one?

              If youโ€™ve been through that many stators you have a problem with wiring, rectifier (if fitted) you need to troubleshoot the loom and other electrical parts to pinpoint the cause...
              Sorry I cannot be more specific...

                No. You'd need to swap out the crank, stator, CDI and a whole bunch of other things.

                    That can all be sorted.

                    https://www.bikerstoolbox.co.uk/acatalog/Multi-Block-Connectors.html

                    This guy stocks many Japanese connector blocks so that you can just reinstall them onto your wiring loom.
