As was mentioned, there is very little to do on the new UCE powered bikes.
You will probably want to get a complete set of metric wrenches and sockets because the RE nuts and bolts are made to the European standard.
Hex sizes like 13mm aren't common on the Japanese bikes but I've found several on my RE.
Although they are adequate for the job, some of the Indian steel fasteners aren't the greatest thing around and in many places the steel fastener/plug screws directly into cast aluminum.
Because of this I highly recommend buying a good torque wrench if you don't already have one.
The only machining I've had to do is to modify some of the aftermarket parts I've installed.
Apparently the idea of precision tolerancing and fit hasn't made it into the designs of some of these and I have yet to install something that didn't need a hole enlarged or elongated with a rat tail file to fit.
