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?
Why did you up to a hotter plug? The jetting is possible depending on your location/altitude. Stock jetting is 35 pilot jet, 75 main jet. Take your carb out and check whats in there. Also you forgot to mention which belt?
Your correct on the plug I had it backwards. The stock belt shredded after a 100miles? Thats not common id double check your cvt, all I run is oem bando’s and have had many last over 1k miles. What belt is in there now?
i’m not looking for a limiter but there is surging above 9k. i know what the stock limiter felt/heard like. I’ve seen this turn 10300 on the tach before.
Yes the NCY CDI has issue at higher RPM. Most can not tell but both that I had would surge at higher RPM it was 9500 and up. I never run any of mine over 9800. I really noticed it when I was riding beside my son. I could hear a very slight cutting in and out. I ended up switching both to the EVI from Rolling Wrench and the issue was gone. I have read about others having this same issue. Most people cant even tell.
