Title: Kymco stumbles at cruise speed?
Post by: JJJoseph on December 06, 2023, 03:32:02 AM
Here's one for the trivia collection!  My Kymco 100 started stumbling at moderate cruise speed (about 60-70kph).  The rpm's would drop about 100rpm every 10 seconds or so.  Really annoying!  I went through everything, clutch, variator, carburetor, plug, coil, etc.  Nothing!  It doesn't have a computer for diagnostics, so I had to figure it out the old-fashioned way, replacing everything one by one until I found the villain.  Well, guess what it was: it was the stator.  It appears they get old like the rest of us and then then start stumbling!  Anyway, I ordered a new one from the dealer in France (AZ Motors), and it arrived 10 days later, plus a flywheel removal tool from Amazon Prime) and after an hour's work it was installed and running like a new one!

Now here's the takeaway for other Kymco owners trying to order parts.  My stator is identical to a Kawasaki KFX90.  There's no Kymco/Kawasaki interchange for parts, and Kawasaki denies that their parts are the same as Kymco parts, even though the Kawasaki parts say "Kymco" on the part.  This time I wasn't sure, so I had to actually order the part from France.  Sure enough, it turned out to be the same as a Kawasaki stator!  Now I have one more Kymco part that can be replaced by a Kawasaki part!

The stator for the Yamaha Majesty 250 fits the Kymco Downtown 300i perfectly!
