i have a 2004 sporty 883 and have never had any problem with the bike, but recently i have been hearing some, what i think to be engine noise but i guess it could be from the tranny also i'm just not sure. its only when i shift thru gears 2-4 that i hear the noise and it is a pretty loud tinging, there is no noise in 1st or 5th thats why i'm not sure if its engine or tranny, i would appreciate any help i could get

 

If it is a loud clanking sound, I would check the obvious first which is your primary chain

 

Also, how many miles are on the bike?
