Noisy Chain

its an Izumi chain.
I'm sure he'd rather not buy another one as he just bought this one! Damn

The chain did come with oil but I put a bit more one as it was so noisy and the cog and chainring were so dry.

is possibly issues with chainring size/chain size as all the above have said, but also keep in mind that izumi chains almost always (at least every one that i've had/my mates have had) sound like tractors. loud chains. get kmc/hkk/did instead. or even sram. much quieter.
