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.

SOURCE: i have an 1974 kiwasaki ke100

this could be really bad or really easy. first, lets hope its vapor lock. take your spark plug out and see if it will turn. if yes, kick it a few times and replace spark plug. if not then we need to see if the kickstarts malfunctioning or the motors lock. put the bike in about third gear, grab the clutch and pull it in, now run beside and push the bike with the clutch in, get some speed and dump the clutch. Hopefully the engine will start turning over, in fact if you have the switchs on you can start the bike this way. If the engine does not turn over like that then you have a drivetrain problem, without seeing the bike theres no way to pinpoint it. Lets just hope the steps above work and you dont have any major problems, good luck.

Hi, Per for this scenario you will need your service manual that has all fastener torque specs and a wiring diagram on the back pages, parts fiche, and owners manual if you can't find the best tool you ever bought for your Kymco, despair not, for a mere zero $0 you can download another one.

2006 Kymco ZX 50 will not start


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.
11. Fuel injectors clogged.
12. Fuel injectors stuck open.
13. Quick disconnect check ball stuck.
14. Compression below 75 PSI.
15. A stuck-bent-burnt valve.
16. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory 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.
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.
24. Tilt sensor needs a reset.
25. Security system not disarming alarm needs a reset.
26. Check for engine trouble codes.

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.

2013 Kymco Super 8 50 2T keeps flooding on startup


Hi, Anonymous if you take your bike to a dealer for a specific issue that costs outrageous amounts of money only to have the same problem 2 days later your situation is not unique unfortunately and it is a double-edged sword. First, you suffer the emotional stress and frustration of spending all your hard earned "Drachma" and your bike does not get fixed. Second, comes the realization that not only are the technicians incompetent but also the service manager for not doing anything about it, this isn't rocket science, it's a glorified lawn mower engine with extra cylinders and carburetors sometimes. You need to put an end to all the double talk, dancing around the issue, and a "we don't care attitude", but how you ask, very simple you exercise the "nuclear option" go back to the dealer and ask to speak to the owner or general manager if the owner is not there, then with a straight face and polite voice you ask him/her if they can provide you with the name and contact phone number of the person at your brand motorcycle headquarters in your country that can recommend a repair facility that will fix your bike because your local dealer either can not or will not. I guarantee you that is all the grease you need to get someone to light a fire under the proper persons rear end to resolve your issue "toot sweet"

Starter makes a clicking sound when tring to start it "


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.
