When installing a new exhaust system, you will need to fine tune and rejet your carbs. If your bike is an EFI model you will need to have it remapped to compensate for the free-breathing exhaust. The most common aftermarket tuner for fuel injection is the Power Commander

Hello, I'm installing new Thunderheader 2 - 1 exhaust pipes on my 2001 Fatboy. I need to know the torque specs on the bolts. Thanks!

Nuts (cylinder studs) - 60-80 inch pounds.
Nuts exhaust support tubes to frame - 19 foot pounds
Muffler support nuts - 19 foot pounds

Keep in mind that these torque values are for original stock equipment and may not be correct for your aftermarket parts applications. Use you common sense when installing the exhaust system. If a bolt looks and acts like it won't withstand the torque, don't try to apply it. People have been working on Harleys for years without the benefit of a torque wrench. It's not rocket science.

Good Luck

I have a 2001 FLSTFI,the bike is popping thru the exhaust during deceleration and stutters and it will cough thru the air cleaner while I am at any speed and any gear.

Check for intake leaks and exhaust leaks, this is the most common problem on these bikes. If you have aftermarket pipes the "popping" will be more distinct. Put on some gloves and cover the exhaust outlets and listen for a hissing from the pipes and around the cylinders.
Good luck, i hope this helps.

I have a new 2010 wide glide i whount to remove baffles on stock pipes will this hurt bike? or due i have to change complet exhaust and intake?

Any change or modification to any of your vehicles systems can effect your bikes factory warranty! Removing the baffles from the existing mufflers is possible with the proper tools but I think that the internal catalytic converters will prevent this. Changing the entire exhaust or just the mufflers should require the addition of a electronic "fueler" to ensure optimum operation as your bike is delivered to the showroom from H-D running lean thanks to the EPA. For the DIYer I suggest looking at for exhaust options and accessories.

Where is the oil drain on a 2000 flstf fatboy?

From the right side of your bike, look under the oil tank and find a hose or pipe running downwards towards the transmission. Follow this all the way down to the lowest part of the frame just behind and to the rear of the transmisson behind the exhaust pipe. There will be a plug in the hose or pipe. Remove this plug to drain the oil tank.

Good luck

Lightning coil

Can't go off your existing setup. But you can get a wr stator and swap it, the regulator, and the heavier flywheel onto your bike. You can find what you need on ebay. Next would be an aftermarket system.

Mikuni jetting

If it's the Sreamin' Eagle Mikuni, it should come jetted close enough to take your bike to someone with an exhaust gas analyzer. That's the best way to get your card jetted correctly with the extensive amount of changes that you have made on this bike. I would advise that you take the bike to someone that has a dynometer that is equipped with an EGA and have the run the bike up. I would not want the mixture to exceed 14:1 at any time and preferrably run about 13.5:1. It's a bit on the rich side but it will help keep your engine running cooler. I've installed the carbs before but I cannot remember what jets they had in them. Sorry. Good Luck.

Exhaust systems

must the exhaust be specific to the model is there no way to take an exhaust made for a similar scoot and fit it to the scarabeo? What is your goal? The scooter exhausts offered by Leo Vince and Malossi aren't actual performance systems. People use them because they want to customize the scoot or get more of a growl sound while also passing emission inspections. Most people in the USA never have an emissions inspection on their scooters and are thus free to bolt on any exhaust they choose. If you are looking for performance you need an aftermarket free-flow system like those used for off-road bikes and your only limitation is how loud of an exhaust you are willing to accept. There are plenty of aftermarket exhausts for pit bikes and small dirt bikes that should bolt on to the S100-4T. Personally I would start by looking at mods people have done on the Honda XR70 since it's about the same size engine and uses the same 20mm Keihin carburetor. Of course if you bolt-on an aftemarket free-flow dirt-bike exhaust you will need to replace the existing restrictive airbox with a free-flow K&N unit and either add larger jets to the existing carburetor or switch to the high-flow 20mm PE Keihin or the 24mm Keihin. Either way, the muffler is the easy part it's getting the fuel/air mix right and that's all carburetor work. ,,,
