It feels like the fuel is cut off intermittently really fast and the rpms will bounce around, sounding like the bike is sputtering as you described and like this...

And this at about 14 seconds into the video...

It should not cause your engine to die though. Sounds like you may have other issues. Mine kicks in at 6300 rpm and sounds exactly like the bikes in the videos. Bike just stops pulling.

when mine hits the limiter, the cut-out sounds way more aggressive than either one of those 2 bikes.

it sounds like i'm not getting a typical sportster rev-limiter experience. Since mine cuts out rather than sputters i have other issues.
Thanks a- lot for everyones helpful comments.....

Maybe you can take a video clip of it happening and post it so others with experience on carbed Sportsters can maybe give you more info and suggestions.

No problem at all. I'm not sure if the carbed Sportster version of the rev limiter produces a different result but I wouldn't think the engine should completely shut down. I hope you get it figured out if it is an issue with soemthing else.

I have experience with two FLHTC's a 99 and a 09. Both bikes were bone stock and the rev limiters reacted very different. The 99 had what I would call a soft rev iimit where it would just level off when it hit the set max rpm's. The 09 has a hard rev limit where it is like you hit the kill switch when you hit the set max rpm's. The 99 was much more pleasant to drive when I was getting on it. The 09 is much more touchy when you get on it and if you hit the max rpm's in 1st or 2nd say goodbye to any good acceleration.

INTERESTING......sounds like they can all react differently. My rev limiter sounds more like your '09. Makes me wonder why some are more aggressive than others. Have you done anything to your '09 to correct it? Does the rev-limiter live inside the ECM? If so, do you think re-setting it would help? Does a code come up when the rev-limiter is triggered?

Perhaps on the carbed bikes the limiter can only affect ignition, since the carb cannot be shut down instantaneously. On EFI, the injectors can be shut down instantly, so maybe they limit fuel supply.
