2021 Honda Rebel 1100 is leaking oil from the left side. Near the gasket/stator. Low miles under 2k. I have read about this problem on other 2021 models. Becoming very common issue. Same spot, same leak.

Honda Rebel 1100 motorcycle footrest has too much vibration at 55 to 70 miles/ hour speed. thus after an hour or more makes the feet num. When i took it to the honda dealer they said that the engine will vibrate due to balance problem. this is dangerous. Look at youtube and other facebook sites and most of the Rebel 1100 users are complaining about it. This engine has to be balanced asap to reduce the vibration at 55 to 70 miles/hour that is the normal riding speed in USA. I almost fell down when i tried to stop at the stop sign.
