I’ve got a 2020 ruckus that has about 900 miles on it that I’ve put on it in the past month. It’s stock other than Ncy Cdi, Ncy coil, ngk iridium 9 heat range plug, polini variator and a mix of 4.5 and 5g sliders.
Periodically it feels like the power surges when at or above 9k. Any chance that a dealer would jet the bike leaner for higher elevation? Any other ideas?
