assuming you were nowhere near those rpm limits during this recent break in miles..?? and it's started all over again anyway....well..anyway, what a major disappointment man, I'd be pretty damn upset they can't make these engines and components work together normal..total bs
today I did push it hard but that is well past the breakin period I was told to adhere to.

Sorry to say this but.....welcome to my world over the last 3 months. I don't think your rev limiter is set to "6800". I believe you'll find the bike is still rev limited to 5800 rpms. Currently on engine#3 .....still in stock form for now.

I hope your bike has no more problems!
stage 3 kits are set at 6400 and stage 4 kits like mine are set at 6800 this is verified in the screaming eagle pro street software, I looked up the rev limiter setting for each kit
this does'nt matter if its a stage kit 3 or 4 from 107 to 114 or 114 to 117 (CVO)
and this is my point that they may have these rev limiters set too high on the stage 3 and 4 kits.

man, trying to wrap my head around these rpm numbers and why anyone would want their big V Twin Touring bike to go there..aren't the high rpms where most of the HP is made? just seems like oodles of torque down lower would be the preferred way to go on these bikes..they're Touring bikes not race bikes..even with my Stage 1 107 I can do 80mph winding it up to 5000 rpms in 3rd gear..and my peak RW torque of 106 is at 3000 rpms...I'm sure it would be a kick in the a$$ adrenaline rush to wind up a Stage 4 but doubt I would be wanting to ride it like that very often...but that's just me and some folks just love laying the hammer down a lot!

this is the stage 4 calibration for my 2017 SGS, the reason the 6800 is grey'd out is because this is the original unmodified factory calibration for stage 4 for my bike.

You would think they ran all these stage 4 kits at high rpms for significant periods of time at whatever the stage 4 map says to determine if the engine has any issues. Clearly it wasn't tested enough given the # of stage 3/4 failures and the need for SB 1450.

I remember this happening close to where I live. riding fast and almost wheel to wheel
26 Brother Speed motorcycles crash on I-5; traffic backs up for miles. "When we arrived on scene, it was ordered mayhem," said Lt. Mike Towner of Tualatin Valley Fire & Rescue. "There were ... two dozen motorcycles scattered across the freeway."
