Harley riders are used to loud clunks when shifting, but our bikes are quite smooth. If the chain pulls on the rear sprocket when 1st is engaged, it is a clutch problem as it is not completely dis-engaged. Still sounds like a cable or linkage problem as 3000 miles couldn't wear out a clutch. I hope one of our forum gurus will respond as I'm not qualified. There is definitely help here. Ok guys, shed some light!
