Signs I need a TBS?
I have a 2008 Wee with about 2200 miles on it. It has never had a TBS. Around 4-4,500 rpm's, mainly just cruising around town, while holding a steady throttle, many times I hear a WAH-OOH,WAH-OOH slight surging, maybe of around 50-100 rpm variation. I can hear it more than I can see it on the tach. I also have what seems to be a high-frequency vibration when the tach gets above 5,000 or so rpm's. I can feel it through the seat as well as the handlebars, while shifting through the gear or on the highway. My gas mileage is usually in the mid 40's either solo or 2-up. Does anyone think that I need a TBS to help with these issues?
