More than likely the ignition module is the cause or the ignition pickup.

Error code 2 is a motor fault, normally brushes. Companies charge a call out fee to send an engineer to you or you can always send it back yourself.

Hi, Pete you may have squeaked your top end this is commonly known as "HEAT SEIZE" the piston heats up expands and becomes extremely tight in the cylinder bore and usually occurs mainly on 2 cycle engines right after a fresh top end rebuild, but it can also happen to brand new motorcycles, these are rare instances due to better quality control and education. Overheating failures that cause pistons to seize are many and each one should be carefully diagnosed to prevent future repeat offenders and the usual suspects are:
1. Lack of lubrication due to low or no oil.
2. Among the causes of lack of cylinder, lubrication is clogging of lubricator by dirt or waste, obstruction in oil pipes/lines, leaky check valves, leaky pump packing, broken oil pipe/line, oil too cold to feed.
3. Wrong type of oil used in premix or oil tank.
4. Improper premix ratio you should start with 32:1 as a baseline.
5. New rebuild piston to cylinder tolerances set up too tight.
6. Failure to follow proper break-in procedures with a 16:1 premix ratio.
7. Loose fasteners causing intake, base, or head gaskets to leak or blown crankshaft seal, failure caused by age, overheating or walking.
8. Holes in the intake manifold bent or warped intake flange or reed cage any stray air coming into a cylinder will cause a super lean condition.
9. Improper assembly of reed valve gaskets.
10. Insufficient warm-up time for temperature conditions before WOT.
11. Broken, pinched or cracked fuel line.
12. Carburetor fuel passages clogged or restricted from stale fuel varnish, ethanol sludge, dirt, rust, or fuel level in float bowl too low.
13. Main jet size too small or partially clogged
14. Air filter improperly installed, missing or not sealing.
15. Faulty or improperly adjusted oil pump and or cable.
16. Failure to bleed oil pump after a rebuild/replacement or running oil tank dry.
17. Engine coolant level too low, too old, or improper mixture ratio.
18. Radiator clogged, fins damaged, or faulty cap.
19. No liquid circulation due to failed oil or water pump.
20. Cavitation due to air in oil or coolant system.
21. Water and oil mix due to a blown head gasket.
22. Timing retarded due to faulty CKP sensor or CDI.
23. Improper spark plug heat range (too hot) and or gap.
24. Excessive engine load, brakes dragging, clutch slipping, transmission lubricant level too low or viscosity to high.

Hi, Graeme the vast majority of service, parts fiche, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee of $15 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available and some were never printed in English. The Indian and Philippine markets are usually in E-book format only, for these rare occasions I shall look on eBay and find the cheapest one available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. If there is no $ sign after the manual link it is free to download.

the sump plug will be on the bottom of the engine but theseold Honda copy (GY) engines don't use an oil filter they have a wire mesh gauze screen that sits on top of the sump plug bolt so make sure this comes out with the sump plug and is free from any dirt/debris. so drain oil clean the gauze screen then refit and refill your oil. check your oil level if its low or black and burnt this could be your over heating problem but I would also check to make sure the auto choke isn't sticking on. Best of luck hope this is of some help

Hello P Smurf,

Well... don't feel bad...!!
The KIMCO drawing is TRASH (in my humble opinion).

Just start the engine!
- ignition switch on (powers on CDI module)
- short B+ 12V to "S" lead (small terminal on solenoid switch = cranking motor (until it starts (or within reason... do not burn out starter)).

Really... you can short BATTERY to the starter solenoid... as long as you have the ignition on... It SHOULD RUN (if it can).

You only have the REAL two issues you need to start...
Fire & fuel... (everything else is mere confusion).

IGNORE IT ALL... until you get the engine started...!!

I've been reading schematics, circuit drawings, operational diagrams... All of it for more than my adult life... (mere seconds away from 70) amateur radio, patent holder & highly skilled professional... (into full spectrum optics)....

I pulled up the appropriate Kymco "drawing"... and while I'll say it is very pretty (colorful) it is also TOTALLY USELESS...!!
(top reference below... avoid it!).

Whom-so-ever (clown who posted it) that put it together
didn't (still doesn't) know their posterior from 75 cents
(six bits).
I can't even tell if the generator & starter are one-in-the-same
(which would be the first place you want to go...

Useable VERSION immediately below...


Quite Useless:
http://www.enmoto.com/enmotoonline/downloads/Specifications/Kymco/Schaltplaene/Quannon.pdf

I found another source... that has the COMPLETE information:

If you don't have a spark tester just have a friend pull the HIGH-VOLTAGE wire loose enough to see the spark jump...

Else find the CDI Module/Coil... & replace it
(better to get a SPARK test tool...)...
I'm just saying

Comment me back... every tractor & tiller in the world has the same starter circuit
(some just have points & coils in lieu of CDI Modules).

I'll be here!!

Hey Tammy,
I hope you mean carburetor -- Motorcycle carburetors have numerous tiny passages, screws that need to be removed to access some of these tiny passages, jets that need cleaning, etc.
This is NOT a job for a shade tree mechanic.. Any good motorcycle dealership SHOULD have a mechanic that can clean and set your carburetor..regardless of make!!

Kymco... | Answered on Sep 07, 2017


How many kilometers has it done? Either one of these is the culprit; battery, spark plug, ignition coil, or CDI. CDI normally seems to go around 25000-30000kms.

hello, there are a few ways to find out the value of your bike/car/4x4 etc but there is a site my parents used which I would recommend. it is free, they require by law just a couple of your details and make/model/year of your vehical plus the reg number and you then get the best quote possible. I would start here and I hope this helps you. https://www.sellbike.com/valuation/

Hi, Sandra and the usual suspects are:
1. Severely discharged or a damaged battery must have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
2. Faulty alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Faulty main circuit breaker or ignition switch, check for loose connections and continuity.
5. Faulty system and or ignition relay, check for continuity.
6. Faulty ignition coil, ignition/electronic module.
7. Faulty CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Fuel tank empty
11. Fuel tank contaminated with ethanol sludge.
12. Water or dirt in the fuel system, or clogged filter.
13. Restricted, blocked or kinked fuel line.
14. Faulty fuel pump.
15. Faulty pressure regulator.
16. Faulty or clogged fuel injectors.
17. Lean angle switch is faulty or needs adjustment.
