Hi I have a Baotian 50cc bt49q 9r. Bike won't start I've cleaned the carb drained old fuel etc, bought a new battery and a new spark plug.CDI might be faulty which I have ordered or the coil pack ?

Hi, Neil and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, 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.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).
11. Security alarm needs a reset.

Why does my baotian bt125t-12 evolution scooter cut out at 5000 rpm?

Hi, Darrell and the usual suspects are:
1. Severely discharged or a damaged battery must 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. Faulty 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. Faulty main circuit breaker or ignition switch, check for loose connections and continuity.
5. Faulty system and or ignition relay, check for continuity.
6. Faulty ignition coil, ignition/electronic module.
7. Faulty 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. Fuel tank empty
11. Fuel tank contaminated with ethanol sludge.
12. Water or dirt in the fuel system, or clogged filter.
13. Restricted, blocked or kinked fuel line.
14. Faulty fuel pump.
15. Faulty pressure regulator.
16. Faulty or clogged fuel injectors.
17. Lean angle switch is faulty or needs adjustment.

Harley Davidson - FXSTI Softail standard cranks but will not start

Hi Anonymous, This one is a tuffy since I don't know what year your bike is. If you have an early model you could have a bad run/stop switch, ignition sensor, ignition switch, ignition module. If you have a late model could be crank positon sensor,electronic control module, but on the late stuff you can pull up trouble codes on the odometer and that would at least point you in the right direction. Good luck

My Yumbo Dakar 200cc bike dies after riding in 5th gear reving medium-highish for a couple of minutes, it usually just dies after i hit the clutch (coasting), but on long runs @ around 50-60mph in 5th gear...

I have a couple of ideas what may help.
First I would think it was starving for fuel.Or maybe an unusual ignition system fault- So how do we find out?
Well-you could try checking the bike for spark immediately after the bike stops.
Remove the spark plug-Re-fit to the cap-place plug resting on metal where you can see it(DO NOT HOLD PLUG-HIGH VOLTAGE)-kick over & check for spark.If theres no spark-try a new plug but if the problem persists then the bike has a faulty ignition(coil,cap,plug,stator.ignition/kill switch,wireing)
I think it is more likely starving for fuel.
A faulty fuel tank filler cap vent or carby vent tube pinched or blocked.
To check the filler cap-ride the bike & when the problem just starts-quickly crack open the fuel tank filler cap to let air in/out. If bike runs ok then the cap is blocked.
To check the carby vents -just look at them & make sure none are blocked or pinched.They usually come from each side of the carby & one from the bottom(usually clear or semi-clear hoses).
I hope that this helps you with your problem.
Regards Andrew Porrelli

Need to change the Clutch Pedal Ignition Switch; do you have instructions how to do this?

Removal & Installation
  1. To prevent accidental air bag deployment, disconnect the negative battery cable, then the positive battery cable to allow residual energy in the air bag system to drain.
  2. Remove the steering column shroud(s).
  3. Disengage the wiring harness connector from the ignition switch.
  4. Insert the key into the ignition switch, then rotate the ignition key lock cylinder to the RUN position.
  5. Remove the two screws attaching the ignition switch.
  6. Disengage the ignition switch from the actuator pin and remove the switch.
To install:
A new ignition switch purchased from Ford will already be set in the RUN position.
  1. Adjust the new ignition switch by sliding the carrier to the RUN position.
  2. Check to ensure that the ignition key lock cylinder is in the RUN position. The RUN position is achieved by rotating the key lock cylinder approximately 90 degrees from the LOCK position.
  3. Install the ignition switch onto the actuator pin.
  4. Align the switch mounting holes and install the attaching screws. Tighten the screws to 50-69 inch lbs. (6-8 Nm).
  5. Attach the electrical connector to the ignition switch.
  6. Connect the positive, then the negative battery cables. Check the ignition switch for proper function in START and ACC positions. Make sure the column is locked in the LOCK position.
  7. Install the steering column shroud(s).
Is this the one you are asking about?

New baotian bt125-t9

wont start as in run or turn over with electric starter? Not familiar with that model but all are similar. May be a fuse in the starter button circuit, key switch connection, may be bad connection at starter button or bad relay. check button for continuity check connections following wires down handlebars to their destination
