As someone new to LC4-s, then I need some help identifying this thing. It should be 620SC from 2000 but I don't get the all oil in frame vs separate thing. SC should have no oil in frame? Also it is missing the microfiber oil filter. So it isnt SC? Maybe the frame is from something else? Also the headlight is not from SC or am i wrong? Been googling this for over a week now and still confusing to me.
