Max RPM setting 103 modified?

Curious, what rpm do you have your rev limiter set at? With what setup?

I have stock springs/heads with a S&S 551 cam (SE255 very similar) 2011 103. My bike makes all of it's torque/HP 2200-4500. I can't really see a need to bump the rev limiter. If I do, maybe a few hundred.

What is a safe max RPM on the 103 in your opinion?

2010 fatboy Lo with 103, 10:5:1, 259E, no head work but new springs and my rev limiter is set at 6200. I also hit it it occasionally as it get there fast in 1st and 2nd gears.

Yeah but your talking pretty serious compression/cams and high performance springs. Bet it's a fun ride!

2012 Street Glide, Woods TW-555 Cams, rev limiter set at 6200 and can find it in the first five, pulling power all the way, very quick in the first three. I wouldn't want to set it any higher than that, though.
