*Everyday riding: Much better! Some loss on the very low end with these cams, but the increased displacement helps make up for that. These cams come on very strong by about 2,500 rpm, with plenty of pull through the entire range (even with 2 people and extra gear), where the original 255 cams ran out of steam after about 4,000 rpm.
*MPG: I haven't checked on paper to verify, but based on the rides I've done, I'd say it dropped 1-2mpg at the very most--still have plenty of range between fill ups.
*RPM's are still the same--no change in gearing or tire size.
*Rest of the drivetrain: Everything should be up to task with a build this mild. The clutch is working well, but likely the 1st weak point. Info from Harley varies--depending on where you read, they say the original CVO A&S clutch is good for 115-135ftlbs, but I will likely be putting an AIM kit in it soon to be on the safe side.
As SMARTY pointed out, the crank can be an issue if abused, but that shouldn't be a problem with my riding style.
