My father passed away last year and I inherrited his Harley. I've had my bike license for a few years, but don't know much about the mechanics of the bike. Little did I know, while I was away at college, the battery in the bike was dying during the winter. Anyway, I know this is a very simple task, but I need to replace the battery. I removed the bolt on the back of the seat but it is still catching on something. I don't want to mess anything up, so I am afraid to try too much on my own. Could someone please help a poor college girl out in getting this bike back on the road? :)

what year is your bike? on my 2005 dyna fxd, there is a small bracket adjacent to the battery box on the right side of the bike. there are two bolts in it. one screws in vertically upward. completely loosen that bolt but do not remove it. there is another bolt that screws inward horizontally. you can remove that bolt. the battery box/ tray should then pull down and angle outward to allow access to the battery. the negative cable should be the first cable removed and the last one connected.
Well, this is an impossible question to answer. There are simply too many variables that one must consider not to mention the unknowns. I've seen the bikes with as much as 75K miles on the bottom end running well. Top ends need freshening up from time to time. Depending on how a person rides the bike has a lot to do with how often this has to be done.
A Harley-Davidson engine, unlike the Japanese engines, have a very heavy set of flywheels. Because of the wieght of these flywheels, the engine will not stop as quickly as the other engines on the market. This is why Harley-Davidson motorcycle have the torque that they do. As for the backfiring through the carb, if your bike has the stock jetting in the carb, it's probably a bit too lean. This is set so that the engine can pass the EPA's emissions standards test. If you richen the slow speed jet up to the next larger size, this problem will be solved. As for the backfiring if you don't allow the engine to warm up enough, any engine equipped with a carburetor will do this when it's cold. A fuel injected engine has an engine temperature sensor that keeps the fuel mixture on the rich side until the engine reaches full operating temperature. There's nothing wrong with your bike, Ride it to Sturgis.
Personally, I think the H-D AGM battery is about the best value out there at this moment in my area. They are competitively priced and they are excellent batteries. If you keep them on a "smart charger" when you're not on your bike, i've seen five year lives out of them typically. The Softail is particularly tough on batteries since the battery is housed in the horseshoe style oil tank. It causes the battery to run hotter than the other bikes Harley makes. I say this simply as a mechanic that has worked on H-D motorcycles for many years. I have no vested interest in Harley-Davidson.
I'm not sure whet the factory battery is rated at because they don't give you the specs on it. I would think somewhere around 300 CCA would be required. Your best bet is to get the best AGM battery you can find. The H-D AGM battery is a good battery and is priced competitively with others on the market. I've had good luck with them.
If you purchase a battery tender or one of the "smart" battery chargers and plug it in after every ride, you'll be surprised at just how long the battery will last. I had one of these batteries for five years and it was still starting my bike well but I replaced it anyway. I absolutely hate having a battery let me down.
If the battery is getting old (4 to 5 years) it may not be able to hold a charge as well as it did. Have it tested, it may need changing. If an alarm is fitted to the bike it will drain the battery as it will use power even in standby mode.
Well his first mistake was buying a Duramax Isuzu Diesel... But with that said, Diesel has a tendency to grow bacteria in the gas tank. Flush the gas tank and change the fluids in the engine and you should be fine. You may notice that some of the gaskets on the engine may leak now that they have dried up. they will either reseal themselfs in time or with thightening or you will have to replace the gasket. I don't think that will be the case after only a few years though.
