    My problem was a faulty vacuum controlled fuel tank switch. The engine stopped after a couple of miles as no fuel reached the carb. Removed the vacuum switch and blew it clean. Now, the valve opens easily and petrol flows as it should. No need to buy a new one. $ 0.
    Hope somebody finds this helpful.

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, John and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the choke.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
10. Carburetor float stuck.

13. Quick disconnect check ball stuck.
14. Compression below 75 PSI.
15. A stuck-bent-burnt valve.

17. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
18. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
19. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections are loose or connected to the wrong cylinders.
20. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
21. Faulty neutral, clutch, kickstand safety switch.
22. Faulty fuel pump or fuse or relay.
23. Faulty or corroded run/stop switch.

2006 Kymco KY-SC10 service manual


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.

U may not have enough power to start the bike, it happens on bikes, get a "house" charger from a local autoparts store if you don't ride it that often. If NOT then your starter may be sticking or a bad connection.
