I bought the T111 for my 1999 Road king. Installation was straight forward. for I had asked a Harley shop what would cost for install they quoted $ 2000.00 to much for me. I figured if Iam going to pay that kind of money for install i would buy a ride on lift and do it myself. The motor was worth the cost no issues so far would have liked to choose my own cam's I have 12000 miles on it. Had to upgrade swingarm bushing's and install grade 8 front motor mount bolts this motor has torque you are going to like it
