Is the 2000 harley heritage softail classic fuel injected or carburetor ?


You'll have to check with either a dealer or look in a "Black Book of Motorcycle Values" to see if H-D offered that year model with fuel injection. Look for a listing for a FLSTCI. The "I" indicates that the bike was fuel injected. I don't think fuel injection was available on the Softail until 2003 but I may be wrong on that. I am not a dealer nor have I ever worked in a Harley dealership. I'm an independent mechanic that worked on Harley-Davidson for years. I'm retired now.

Good Luck

I have a 2003 heritage it started poping through the intake and has no power drain the gas and put new gas in and it still pops and has a hard time pulling its self only 8000 miles


I'm going to assume that this is a carburetor equipped machine. The spitting back out of the carb sounds like you're running lean for some reason. I'd check for a vacuum leak somewhere. If you don't find anything obvious, do a compression test on the engine and see what you get. There is a possibility of the cams being out of time but with only 8K miles, highly unlikely unless something has went terribly wrong.

If the bike is fuel injected, I don't have a clue what's wrong. I know nothing about Harley fuel injection.

Good luck

How to slow fast idle in heritage softail


Sorry but you have to take it to a dealer or someone with a box that can adjust the idle speed. Your fuel injected bike is just like your car, there isn't much can as an owner can do to them anymore. It's been headed that way since 1999. The days of fixing your own motorcycle are slipping away quickly. That's why I'm keeping my old bikes. I can still work on them.

Good Luck

Stalls on cold start up


Now, I don't know a lot about the electronic fuel injection systems on Harleys but I would guess that there would be an engine temperature sensor on the engine somewhere that would tell the computer that the engine is cold and to enrichen the mixture. The engine should go into high idle speed until the temperature comes up to a certain point as well.

I have a 2001 softail duece, fuel injected that idles too high.


If it's fuel injected, the dealer will have to set the idle speed for you unless you have another type of computer on the bike.
