Okay, I have a newbie question. I've only had my 2000 Classic a short time, and still trying to figure out what I bought -- not sure the guy who sold it to me even knew. I'm getting some popping on decel. Improved somewhat when I filled the tank with Premium gas -- suspect the previous owner might have used Regular. Anyway, still having the popping when I get off the throttle. Bike has V&H straight shots, but not aware of any other changes. Idles well and runs well, so no other noticeable problems. Any ideas what I need to do to correct this popping problem? Thanks.

 

Check for an exh leak first

 

V&H straight shots will require the use of either SERT (MM), PCIII or other MM compatible EFI Mgmt system.....

TC88 Magnetti Marelli EFI systems are actually sensitive to mods like that.....

Find out or look for your "Add-On" EFI management system....

 

Bob, since I don't have anything that came with the bike, if it has had a SERT tuning change, would I take it to my local HD dealer to have it retuned? Is this something I could do myself by buying the software and cables?

 

If it has/had a SERT (MM), you SHOULD have recieved the interface key with the bike......

If it is Race tuned, any HD shop with a Digital Technician can plug in and see what the cal and Race Tune status is.....

If by chance it is, you NEED to get ahold of the key, or you will invest in one yourself.......

You might find out that it has a Stage I ECM update and nothing more.....

That is not enough for that system.....

The cal that you PROBABLY have is 29489-99/DT.......

That is a 1450 Stage I Legal....

 

Thanks, Bob, lots of good info. Like she says on TV, "I don't know what it means, but I want it." Gives me more to learn and provide info to my dealer. I plan to pull the seat later today or tomorrow and keep digging into what I've got installed. I've got a lot to learn!

 

Is the bike carbureted? The post does not state.

 

Nope, it's fuel injected. I'm sure that's a good thing, but sure seems to be a lot more to learn.

 

T his is very easy to correct with a power commander.

 

Yep, I'm going to have to invest in either a SERT or Power Commander to get this cleared up. From what I've read the Power Commander is easier to use, but SERT has more capabilities. I'll keep reading on the forum to try to make a decision as to which to get.
