Sometimes, when we are riding, the bike will suddenly not run right - sputter, but not stall - no power. Then it will go away - and then it will start up again. Engine does not fail to start, but applying throttle causes sputter and inconsistent rear wheel spin.

This has been happening intermittently with my 2016 Kymco Super 8 150. Today, it didn't go away as quickly as usual, so my daughter's boyfriend came and picked us up on the side of the road with his F150, and we dropped the scooter off at the Scooter Genie. I needed an oil change anyway...

Of course, it did not act up for him - but, from what I described, he seems fairly certain that the CDI is acting up. Now, the Scooter Genie primarily deals with Chinese bikes, so he doesn't have a CDI replacement for my scooter. The part number (from my CDI) is 30410-LFC4-E10 - an 8-pin connector. $69.

is most inexpensive I can find online (Amazon - www.amazon.com/MODULE-KYMCO-SCOOTER-SUPER-30410-LFC4-E10/dp/B07252Z1QV/ref=sr_1_2?ie=UTF8&qid=1493512245&sr=8-2&keywords=30410-LFC4-E10)

Scooter Genie says "CDI's are a tuneup/maintenance item - you should always have an extra one on hand - they are only $16.99 or so". Well, if they are about $20 apiece, I'll take 2 - but not at $69.

!

Anyway, while riding later in the day, it happened again. I pulled over, removed the battery cover, unplugged the CDI, plugged it back in, started scooter back up, and all was well.

So, what do we think, good people? Is it likely my CDI that is causing problems?

Parts for Scooters and Scrappy Dog don't have 8-pin connector CDI's...

And of course, since it is an electrical component, the CDI is not covered by warranty...

Floridagull,

My old Chinese 150 did the same thing, and it indeed WAS the CDI. I'm a big Kymco fan, but the little parts DO cost a lot more than universal Chinese makes. I'd try the Net to see if you might find one cheaper, maybe on eBay even.

I'd advise you to get a new CDI as soon as you can though, and keep it with you, just to avoid a long walk n' push... Kymco parts are known for being very long-lasting, but they CAN go bad like any others.

Best wishes for many more happy miles!

I just checked eBay, and OEM CDI's are pricey! However, I did find this one ("New Racing" brand) that appears to interchange with yours.

eBay item number:
311840687916

This "blue" "New Racing" CDI may be very good. I replaced my bad CDI on my old Chinese 150 with one, and it was GREAT. No rev-limiter, and the engine REALLY liked it... and it lasted!

Hope this might help.

PS: Do NOT get it wet! NO CDI including Kymco factory ones take well to spray-washes... REALLY!

Thanks! That e-bay item number took me to a 5-pin connector, though - and I need an 8-pin...

Did I miss something? Can you give me a link to what you saw, if it is different than this - www.ebay.com/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR0.TRC0.H0.TRS0&_nkw=311840687916&_sacat=0

That is the right item. I'm not sure which CDI's made for Chinese scoots might be the correct 8-pin, but it's likely you can find one on eBay. Your Kymco probably uses the same CDI as my old 250, but I've never removed it to look at it.

If you search eBay, you should find one that works... Sorry about my mistake. I did have great results with the "New Racing: brand, in spite of the stupid name... LOL!

Here's another couple to check out. Sorry, but I can't get the links to show up.

The last number you provided - the 729 number - looks right!

www.ebay.com/sch/i.html?_odkw=272641260654&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.X272434453729.TRS0&_nkw=272434453729&_sacat=0

Why is it $36.

, when all others are $69.

- $75.00?

Stopped in at my Kymco dealer to see if he had a CDI in stock - and how much it would cost. Turns out the CDI IS covered by the warranty -

- if it turns out to be that... Bobby seems to think that "if the CDI is bad, it wouldn't be intermittent - when they are bad, they are bad"...

I guess we'll see...scooter is at his shop..of course, no problems on the way over there...

GREAT NEWS!

My Chinese CDI definitely DID go bad "off-and-on" (simultaneously with the Chinese coil, off-and-on) Cheesh, what a pain to diagnose!!! I finally replaced the CDI which "cured" the erratic running about

%, then I replaced the coil with a Japanese Bando coil and THAT finally fixed the electrics for good.

I'd think your Kymco dealer could run a diagnostic test while you're there for little or no cost, and then you'd know for sure. Even my stone-age Grandvista has a lot more electronic voodoo going on than an old-school Chinese ride. These Taiwanese rides are a little more "car like" in design, while the old Chinese rides were a little more "lawn-maintenance-equipment like"... I think, but am not sure (LOL) that a Kymco dealer should (?) be able to diagnose the problem for certain, and, HOPEFULLY the fix will be fully covered by warranty.

From my experience with the old 250, as well as contact with other Kymco riders, these scooters seem to be almost "bullet-proof". Well, Almost... LOL! But certainly among the best made scoots out there.

From two years of basic maintenance, and digging into the wiring to set up LED driving lights, I'm more than impressed with the quality of build. These scoots are beefy, heavy-duty and are literally "little family sedans on two wheels".

Best wishes for a quick, cheap fix... and Ride safe!
