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!

I can only view the first page of comments in the new forum.  At the bottom of the first page I see:

I've asked before from time to time, but yet to find an answer. I have a  100cc Kymco Kiwi, exactly the same as a Kymco Sento, but with a much bigger engine & transmission.  I can't find where it comes from, so I can't find where to buy parts.  The engine top-end is the same as a Kawasaki ATV, and the drive also has a bigger ATV clutch. Does anybody have an inkling where these come from so I can find a source for repair parts? PS: FWIW, it's a really excellent small scooter, good for 90km/hr, probably the best small-frame scooter I've ever come across.

I'm trying to find a way to order Kymco parts.  There's some excellent on-line catalogs in places like France and Germany, but I'd like something in North America if possible due to the cost of shipping.  All that a mechanic needs is an illustrated parts catalog like this one:

https://www.bike-parts-kymco.uk/

It's a UK site, but based in France. It's an excellent online catalog for Kymco parts, but it doesn't have North American models.  Also shipping parts from France is really expensive. Does anybody have info on a North American site?

After beating my Kymco Sento senseless trying to get just a little more speed, I finally broke another crankshaft and scrapped the entire machine. I then found a rare Kymco Kiwi from Taiwan, which is a 100cc Sento which is a real rocket compared to the 50cc Sento.  From a slight distance, the two machines look exactly alike, but the stock engine in the Kiwi is really snappy, capable of 95km/hr compared to the stock Sento's 45km/hr.  The Kiwi can manage local highways no problem.  But my question for the forum is"Where do I find tech information on the Kiwi?"  It looks like a bigger QMB engine, but it's obviously a real thumper compared to the 50cc version.  But there's no online information on the Kiwi, no forum topics, no parts information, no nothing (as the saying goes).  Does anybody on this forum follow the Kymco Kiwi?

The crankshaft on my Sento 50 broke, so I'm looking for a complete used engine to replace it.  Does anyone in the Kymco community know if  the 50cc Kymco Agility engine will fit in a 50cc Kymco Sento frame?  The engines look similar, but I'm shopping on eBay and it's hard to tell from the photos if they're exactly interchangeable.  My reason for asking is that there's lots of Kymco Agilitys being parted out, but very few (as in none) Sentos.

Following my question about getting along without a Kymco dealer is the problem of diagnostics without dealer tools.  I'm OK with my 10-yr old GY6 powered Kymco, but can't figure out how to maintain a new fuel-injected Kymco without Kymco diagnostic tools like on cars with OBD-2 ports.  I can't see a source for Kymco diagnostic tools.  Any suggestions?
