Easy
i,m a back yard mechanic and this was a treat to put together. directions were easy to follow, but if you own a 2007 with efi don't forget to upgrade the electronics to feed the new horses

nice fit
easy to understand directions, took one day to get the bike up and running, one thing is that going from an 883 to 1250cc you need to add electronics to feed the monster i installed, but now i have a very hot running bike.
