hello, when i am in first and second gear i can hear a slight knock which seems to come from somewhere near my right ankle. i can tell if its the engine or something loose. it is not consistent either sometimes its there sometimes it will be less than other times, i inspected the side of the bike though for anything loose and i found nothing. Anyone have any ideas? thanks.

 

it's too hard to pinpoint a noise if it can't be repeated consistently.

check for something loose around the ankle area.
