Hi, Anonymous 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.

Hi, Asa 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. Failed 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. A failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, stator, magneto, ignition/electronic module.
7. Failed 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. Faulty or corroded kill switch.
11. Accelerator pump damaged or not working.
12. Water or dirt in the fuel system, carburetor or filter.
13. Restricted, blocked or kinked fuel line.
14. Fuel tank empty.
15. The gas cap is not venting properly or fuel tank venting system blocked, loosen the gas cap and go for a test ride.
16. A failed fuel pump, pressure regulator and or fuel injectors.
17. Vacuum line from the intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
18. Needle and seat stuck closed in the float bowl.
19. Petcock clogged or damaged.

Hi, Blades13_4ev parts swapping is common with most motorcycles when it comes to interchangeable or compatible parts from one model with another "EXCEPT" for the CDI's they are year-make-model "SPECIFIC" the best thing to do is call your local Dealership Parts Department or a reputable independent shop. If your location is not near a shop then go online and find a parts catalogue or "FICHE" and match part numbers depending on your criteria.

Hi, Anonymous the starter clutch is a separate mechanical gear driven component that is activated by the starter motor, it engages the clutch pack gear or the flywheel gear to turn over the engine. It has an internal mechanism that allows the gear to turn in one "ONE DIRECTION" only and once the engine starts allows the gear to free spin with engine rotation. If the starter gear free spins in "BOTH DIRECTIONS" then the drive gear has failed, it might be serviceable on some models but usually needs to be replaced.

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.

Hi, Anonymous 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.

2008 KTM 530... | Answered 22 hours ago


Hi, S_s_ceramics your instrument gauges and lights can alert you to most electrical and engine issues they can not warn you about failed engine gaskets or seals so your engine has to resort to old fashion alert methods of colored "SMOKE SIGNALS" here is a breakdown of their meaning:
1. COLORLESS OR SLIGHTLY BLUE SMOKE on start-up means your air/fuel mixture is the right composition and everything is well burnt in your combustion chamber.
2. BLUE SMOKE on startup is usually caused by failed valve seals dripping oil into the combustion chamber when the engine is not running.
3. YELLOW OR BROWNISH SMOKE at start-up means your air/fuel mixture is too lean. Too lean means that there is low fuel but high air mixture in your combustion chamber.
4. WHITE SMOKE on startup may be caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers. Smoke while riding is usually caused by worn out or damaged valves, seals, guides, pistons, rings, or cylinder walls.
5. BLACK SMOKE on startup is usually caused by too much fuel in the combustion chamber this can be due to air/fuel mixture adjustment too rich, accelerator pump improperly adjusted, faulty choke or not in the off position, air filter dirty and clogged, faulty carburetor float needle and seat, pilot jet too large, fuel injectors leaking, smoke while riding is usually caused by the main jet being too large or a damaged carburetor.
It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.

2. Broken kickstart return spring.
3. Bent kickstart lever.
4. Bent kickstart lever shaft.
5. Locked up transmission.
6. Locked up engine.
