2003 Suzuki Intruder one coil fires and one does not put on a new and it did not solve the problem, does anyone have any ideas?

SOURCE: battery

Take off battery cover - two bolts. Take out two screws, one on each side, located near top of battery case. There was another bolt, I do not recall where. No need to remove the ones from the bottom. With the bolts out, the case will swivel a little toward the front tire. Then slide out battery.

Hi Lcyr. 
Any changes you make to the exhaust system will alter the sound the bike produces. The more you cut baffles,and open up the exhaust, the louder it will get.  What you do alter to a greater extent,is the state of tune of the motorcycle. Any changes to exhaust or inlet plumbing will require a retune of the engine to suit the modifications. This can be subtle to dramatic. Opening up exhausts can often rob low end power where exhaust port scavaging is relient on some back pressure for maximum effect.
 Best to work directly with an engine tuner to do the mods that are known you can get away with, or buy aftermarket prebuilt pipes that have a known previously tested state of tune. Nothing worse than doing something, that then costs money to put back the way it was on finding out it didnt work as well as was hoped.. Hope this has helped you steer your custom mods a little.  I can say with certainty, that I have ventured to do what you are doing many times in the past, and it has always cost me more money in tuning and... and well more parts :)  Cheers

Sounds like water in the gas. ALWAYS have a fire extinguisher on hand when working on carburetors.
For each carb > Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Put the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.

Please rate this solution. Thanks!

You need to buy a volt meter and set it on 10, or 20 v-. Start the bike and see what it says. A good charging system will show 13-14+ volts. If the meter says 11-12 volts or does not change, you have a bad stator, or rect/reg. Take to a shop to have it further tested. Chaz Moto DC

Did you sync the two carbs? If not the rear may be getting all the gas from the rear carb and none to the front. Twist throttle engine off and see if front carb cable is pulling the carb open.
Also unscrew the spark plug boot from the front spark plug wire and trim 1/8th inch off the wire and screw the boot back in. The plug wire end may be corroded on that wire.
