      Hi all, sorry if this isn’t the right place, i was having a look at the shop and was considering picking up some new coils and an uprated reg rec, my question is how can the regulator be plug and play, wouldn’t the connections and or wiring layout have changed over the years? Thanks all.

      Hey Pete!

      Great questions there.  Hope this answer helps!

      1. ALL “GT125” since 1998 use the same coils , same CDI , same regulator.
      2. They started with a small grey regulator –> then they tried a slightly bigger black regulator a few years later (since 2010 i should say)
        (but both fail too much!)  They can’t even do 14.6 volts!
      3. They tried to use a newer coil from a 250-EFi (which also works with Carb bikes)
        However, no power difference whatsoever.

        The upgraded reg/rec uses MOSFET tech regulators, which are much more efficient than 1970’s serial/diode tech (Hyo).   Very common on big Kawasaki machines, so you know the Japanese don’t like for things to fail.

        And I know Kawasaki machines myself,  so i studied their electrics in comparison to hyosungs.  For example, I would know which pins are plus / negative , how much volts per wire etc…

        650 owners = 2 major mods they always do = Drop a 250cc Ninja Magneto &  Regulator as the 650s REALLY do cook their stock regulators , so an upgrade was necessary.   Hyosung would just keep on sending the same stock ones which would again blow up.  No change.

        125ccc = All standard hyosung regulators cause so many problems, it’s beyond belief.  Just go on our facebook group,  also chinese versions have set the bikes on fire & smoke on dashboards.

        So I never ever sell them, (too much liability)  – Kawasaki tech wins.

        Wiring Harness =  125GTR / GT125 Nakeds (all) –  Same plug, No change whatsoever.

        Ignition Coils = Also a bolt on fit , just look at the shop gallery, so many bikes  2007 plate , 2016 RC ,  2012 model etc…  Kawasaki race parts here again.

        People tried Suzuki SV650 coils on 125, they don’t work.  Placebo effect lol.

       

      Remember, no one goes to a mechanic under my watch,  I got you! –
      For a total novice biker Even clutch change was done at home without paying a random mechanic £200 to do it!

      Oh by the way! – It’s a great shout check your spark plugs , if they are the “stock ones”   (CR8E)  – Just bin them.   Too heavy & fouls too much.

      CR8E IX”  (Blue iridium)  or  CR8E-Lasers work best! – The coils & reg rec work best with IX or Laser plugs definitely.

      Remember, this colour below = a very happy hyosung motor (Good sparks, fuel, air)
      (All coffee brown ring/dark biege center)
      ngk laser iridium plugs hyosung cr8e ix

      If there is anything i missed, just let me know!  Have a great weekend.
