For those of you using a late model (motor hung from upper frame spars) motorcycle engine in their build, how are you bolting the motor to your frame?

My 2004 Yamaha R1 motor has the mounting points shown below, as well as two more tapped holes on the other side. Those were not really usable in my application, so I just used the side mounting points. Here's the best picture I could find. It's a bit tough to see, but on the right hand side I have some steel round stock welded to the HSS stubs and a hole drilled to let the threaded rod through. Then on the left side, I put round stock in and tapped it with I think a 3/4" thread. Then a threaded insert goes in and passes the threaded rod through that. Once in place, the threaded insert is tightened against the engine to eliminate any fore-aft movement. Basically just replicated the same system as was on the original bike.
