I am a new Spyder owner 2015 RT Limited with CB and XM Radio. I use a headset for listening and sometimes when starting out I get an audible "dong, dong" in my headset. Can find nothing to identify this. There are no indications of a failure on the dash readout. I also get a vibration felt strongly in the floorboards around 70 to 74 mph. Also, felt at that speed when climbing a hill. Is this possibly from the drive belt? I find gas mileage around middle 30's. Normal? Installed the La Monster stone guard and find it chaffs on the tire. Any input will be appreciated.
