My brother has a 2004 ktm pro senior 50 went for a ride after 20 minutes it died and now the spark just comes and goes..can someone help me, please


Hi, Bowe the following applies to carbureted also fuel injected models and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
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. 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, 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. Air/fuel mixture screw improperly adjusted.
10. Water or dirt in the fuel system, carburetor or filter.
11. Restricted, blocked or kinked fuel line.
12. Fuel tank empty.
13. The gas cap is not venting properly or fuel tank venting system blocked.
14. A failed fuel pump, pressure regulator and or fuel injectors.
15. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
16. Needle and seat stuck closed in the float bowl.

'87 Yamaha ProV 50: Will cold start and idle well. After a full throttle 1-2 min run will begin & continue running very rough near idle. Will die without addtl throttle imput.


Hi Roderick:
I'm not familiar with your engine configuration, but on some of the older bikes, vibration eventually can cause a wire to break in the coil. When the engine is cold, the wires make contact and it runs, but as soon as it gets hot, the connection is broken or compromised and the spark quits or drives you crazy.
Since your bike runs when cold and quits when hot, I'd be looking for electrical rather than fuel problems.
Hope this helps.

Ktm 625 wont idle when hot


Sounds like idle jets are still clogged, they are really small and unless you check them, a standard cleaning of the carbs may not clear them. I use a nylon bristle pulled from a scrub brush to **** out the pilot jets.

New spark plugs last 10-15 minutes of riding


Hi and welcome to FixYa,

Offhand, the only factor to be checked that could foul a sparkplug for your bike would be the 2T oil injector/pump. There is too much 2T oil going to the combustion chamber. Either the injector would require restricting or for some reason, there is also 2T oil in the fuel tank (pre-mix).

Good luck and Thank you for using FixYa. Happy Holidays.
