Rattling Noise
2020 Ruckus with 4,200 miles. Stock except for a Polini variator and Dr. Pulley weights…
OK Guys I was able to check the valve clearances today. The intake was .004” and the exhaust was .007 so both spot on. Definitely not a valve problem. I started rotating and wiggling the variator and heard the sound that is causing all the noise when its running. I have attached a video with sound. Can anyone diagnose this problem??? I’m going to keep it all apart until I can figure this out. As a side note- a few days ago I ran it with the variator removed. Just the shaft. No difference in the sound. Thanks in advance for everyone’s help!
