Lion-O

I used Castrol T4 10/40 its something like that i went to halfords and the have a book off bikes and what oil is used for what so you know what you are buying. the clicking noise hasnt stoped the bike from handling or running smoothly it just doesnt sound right...

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.... chrs
