Quite an increase in output.

How does it affect everyday riding? MPG? RPMs at 70 mph?

Is the rest of the drivetrain up to the task?

Forgive me for failing to do my due diligence and research, but what were the original numbers on your scoot?

RPMs to MPH will be the same unless he changed the gear ratio somewhere in the drive train. Adding HP/TQ alone will not affect it.


MTrider,

Great numbers! Looks fun so keep us posted on how it does for everyday riding!

Nice job. Just take care of the bottom end. No high revs and dumping the clutch. Be a big uh oh. If it's tuned right, should get 40-42 mpg easy.

*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.

I didn't do a baseline dyno on the bike when new, but based on what I've read, a stock CVO would be 80-83hp.
After the 1,000 mile break-in, the only change we did was replace the factory pipe with a Python Rayzer(short 2into1) and ended up with 90.24hp/113.31tq after tuning, so I gained an honest 35hp with the 117 kit.
