Ah,sounds like its knackered mate,..get rid and get yourself a nice 999.
(Well this is the 749/999 board!)
But seriously tho,
Very difficult to diagnose noise faults without actually hearing them.If the bottom end is knocking it could be the dreaded oil gallery plug has dropped out.The main bearings get starved of oil and bingo its full engine rebuild time.Why not take the bike over to an expert like Nelly at Cornerspeed fot a propper diagnosis?
