Thanks. I await your replyI have a 99 T bird that I got last December but have only put about 200 miles on so I don't know if I'm much help. They are old carburated motorcycles and the vibration your feeling might be normal, I don't know for sure. Next time I take mine out I'll concentrate on your issue.
I'll do that and post my findingsI would check your chain and sprockets for adjustement and wear .
