Hi, Anonymous and the usual suspects are:
1. 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 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. 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.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.
9. Improper valve clearance (too tight).
10. Check for generated diagnostic codes.

Zongshen... | Answered on Jan 04, 2020


Hi, Armand if you are experiencing excessive oil coming out of the crankcase breather or air filter please drain all engine oil and replace half of the same oil that comes out. Many riders are overfilling their oil system because they do not know how to properly read their oil site glass or dipstick. The following procedure works on nearly all 4 stroke engines but to be on the safe side you should refer to your owners manual. Use your center stand if you have one.
1. Bring the engine up to operating temperature or let idle for 5 minutes.
2. Turn off your engine and let it sit for 2 minutes, this will allow the oil from the top end to drain to the bottom.
3. Hold your bike straight up or on the center stand and wait 2 minutes for the oil in the bottom of the engine to be level in the sight glass or on the dipstick.
4. Your oil level should be between the top full mark and the bottom add oil mark.
5. Never overfill your oil system it will cause problems:
a. oil leaking out of exhaust pipes.
b. oil leaking out of breather pipe/hose.
c. oil carryover into the air cleaner.
6. Your oil site glass must "NEVER" be, completely full or empty drain or add oil as necessary.
7. Your oil dipstick must "NEVER" be over the full mark and should never be below the add mark drain or add oil as needed.
