Out riding the other day, came across a line of slow cars on the highway and pulled out on my 2012 Fatboy and cranked it open hard and it died for a second just before I could change up and I backed off and thought WTF was that about? any ideas please.

rev limiter?

Probably good that its got one then, thanks.

I think Kimbo is quietly bragging! Maybe it's time for a race tuner/ power commander/ Thundermax/ Fuelpac etc with rev extend! then you can have more fun.
