just bought a thundercat and i been riding it for a week sounds lovely!!! 
 
today i put oil in her cos she was low and carried on riding i been giveing her some welly 
and i changed between first and second but hit neutral but it made an odd noise and now the engine clicks 
when idle and clicks faster as you rev her i was doing about 50 when i changed.... 
 
can anyone help me on what it might be as this is my first bike and im new to riding....
