Yes, you are correct, those are the two pieces that could solve your problem, but i would go first for your cdi, you may choose to have it tested first also, before you jump out to buy a new one.

2007 KTM 450 SXF no spark


Hi, Tanner and the usual suspects are:
1. Fouled spark plugs.
2. 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.
3. 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.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or electronic control module.
7. Faulty pulse coil.
8. Faulty CKP, CMP, or BAS sensor.
9. Faulty ignition switch.
10. Faulty run/off switch
11. Tilt sensor needs a reset.
12. Security alarm failing to disarm needs reset

I have a 2007 KTM 450sxf after i ride it it dies within a minute


I'd start with simple things like checking the plug and doing a few electrical tests.Some tests you may be able to do yourself like resistance checks.Compare the following spec with what you get ; Primary coil . 25~35 0hms Secondary 5050~7550 Valve clearance inlet 0.10~0.15 exuast 0.15~0.20 both cold and in mm.

STALLING AND LOSING POWER WHILE RIDING


If battery is running down. The engine may not be charging the battery. Check charging system. If running on battery, the bike will run fine for awhile then die as the battery can no longer provide spark to the engine. If charging system is less than 13.0 volts could be a ad stator or regulator. Make sure the battery posts are clean, a bad ground can cause problems too.

2005 ktm 450sx not starting


I also had a bike rebuilt on the top end, which also poped when kick starting. I thought it was going to start, but never did. I used a compression tester gauge on it and found that I had 60psi instead of 100psi. I had it rebored buy a different shop and they informed me that the last shops equipment bored the cylinder oblong instead of cylindrical.
I was out the money from the first shop but I did get it fixed. Hope this helps

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.
