Question about 2002 Harley Davidson FXSTB Night Train

1 Answer

Upgrade the exhaust

I've got an '07 Night Train. I'm looking to upgrade the exhaust and have gotten about a million different answers none of which is helping. My question is can I just upgrade the exhaust with something that sounds and looks better than stock without going into all kind of mods right away. I know that half the fun of owning a Harley is customizing it but for now I'm just looking for some advise on the pipes. Do I have to install a race tuner ?? Do I have to get it Dyno'd ?? What advantage is there to using an entire new exhaust vs. slip on's ?? Do I need the high flow air filter?? I understand the Harley dealers love to upsell but do really need all that stuff just to get some better looks and sound ??

The 07 bikes have the 02 sensors hat self adjust in cruise mode. The problem is that the mixture is real lean in this mode for EPA regs. When you add just slipons, the mixture will become a bit leaner and the 02 sensors will self adjust. Problem is they can only self adjust so much and are at the edge of the air fuel ratio that will give you a good running engine. With the addition of a fuel adjusting unit, whether it be a SERT or a PC III or TFI, the fuel will be richened up to a more workable ratio and the bike will run better and cooler. The Stage 1 intake is optional but consider the addition of the stage 1 with slip ons and a fueler of sorts will add about 10-12 HP and also TQ which will make the bike run better and a bit cooler also.

Hi, Alex and the usual suspects are:

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.

Will not idle down


You have to take it into the dealer and have them adjust your idle with the digital tech, thats the only way to set the idle on these newer injected bikes.

Security System


You need one of the key fobs, or the access code to release it through the handle bars. you should have gotten these when you purchased the bike.
If you have access to neither, then you will have to take it to your local HD dealer and have them reset the system for you.
