Vibration??

[89minijeep]

I just installed a remaned motor into my 89 xj. when the motor gets to normal running temp around 2000 to 2300 rpm there is a vibration from the motor. after 2300 rpm it stops. if any of you have had this problem please share... pulling the motor agian would really suck. thanks though
