hey guys im new here. last weekend i was riding and all of a sudden i shifted to 2nd and there was nothing there only 1st was working. noticed gear lever was loose so tightened it then it selected 2nd and it worked but nothing after 2nd would work. it will actually select 3rd gear but just revs like its in neutral can anybody shed any light? and i drained my oil and there was silver shavings in it very fine but no chunks
