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!!

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.

Hi, Michael there are few things you need to look at when trying to troubleshoot your scooter for power loss. How does it sound? If you run it wide open throttle when warmed up, does it peak out? or stutter? is it loud, or very quite the symptoms can help decide what to try. When you are going full throttle, the engine should get to a high RPM and sound smooth here are a few things you should look for:
1. Plugging air intake- will start well cold, but be hard to warm up and not reach top speed. The engine will stutter at high RPM.
2. Open air intake- to much air or air cleaner is disconnected- engine will not have power at high speed, make vacuum cleaner sound. Acts like it's running out of gas. ( sounds almost the same as a dirty carburetor.)
3. Plugged exhaust port the engine sounds and runs good, but has no power. Slow to take off. Same as plugged muffler, but if the muffler is plugged you get a very smooth exhaust note at idle. Humming instead of pop pop pop pop.
4. Fouled spark plug- backfire. If you get backfire, pretty good chance the plug is fouled.
5. On models with belts, the gear ratio drops as the belt gets thinner (most hondas have belts).
6. On a moped with high mileage, the belt will cause slow top end speed if worn thin.
7. If you have a bike with chain drive in an oil bath and you "OVERFILL" the oil amount in the chaincase, that makes for slow running as it requires too much power to turn the oil.
8. If your engine does not rev up well and stutters or sputters, like when it is cold with the choke on, the engine is running too rich. (too much fuel).
9. Is the air filter soaked with oil? Clean with soap and water!
10. Is the air opening in the airbox plugged? Very common for a spider or mud wasp to build a nest in one of the intake holes.
11. On some scooters it is common to get a leaf stuck in the intake port of the airbox, causing a 10mph drop in top speed.
12. Don't try to adjust the screws on the side of the carb to get lean or rich, as they are for the idle circuit only.
13. The idle air screw should be about 1 1/2 turns out on most scooters.
14. Say your engine revs but kind of wheezes or acts like it runs out of gas it is common to have a buildup of hard carbon on the inside diameter of the hole in the main and pilot jets, and it must be carefully removed.
15. If your moped does not idle the pilot jet is likely plugged.
16. Anytime a moped has not been used for 1 year or more, and still has the same fuel in it, good chance you will need to clean the jets.
17. The poor quality of today's gasoline has made this a rather steady bet.
18. Mopeds are affected more than most vehicles because the small size hole the jet requires is easily plugged, even by thick oily fuel, or water.
19. Drain your carb once in awhile! Most have a screw of some type at the bottom (where the drain needs to be) of the carb.
20. Make sure the air boot to the airbox is not on wrong, kinked, hard and shrunken.
21. Don't oil the air filter if you got the stutters.
22. On some scooters, you can leave one snap loose on the airbox lid to allow it to crack open, to get full rpm.
23. "WARNING" too much lean out on the gas, and since the fuel cools the piston, the piston can "MELT"
24. Still slow? Check the muffler tip. Make sure no carbon buildup is inside the tip, stick something in as far as it will go.
25. Common on some scooters to have the tip bent over on a curb, then carbon up solid. common of all types to have the whole muffler plug.
26. When you have the muffler off, is it heavy?
27. Can you get the baffle out to see if the holes are plugged?
28. Check the exhaust port on the cylinder.
29. If you can't see all the way into the piston, use a mirror and a flashlight to make sure the piston is ok and the port is not plugged where it meets the piston.
30. Common on all models to plug here, Just scrape it out so the hole is full size again.
31. Don't worry about the small film on the inside of the port, I am talking about a very thin film that forms a wall in the exhaust port right next to the piston.
32. A 1 1/2 inch hole can be reduced to the size of a pea...... With a thin film of carbon.
33. If you can see the piston ok, it's not the problem.
34. If you are in doubt regarding your exhaust pipe being plugged, put your hand behind the muffler to see how much pressure is expelled. compare to another bike.
35. It should blow pretty good and have a distinct pop pop pop pop sound while idling, not a steady humming.
