OK, subframes are on. There is an order of operations here:
1) I install the front subframe first (part with the upper triple tree and fairing subframe) and use bull pins/screw drivers to hold the back struts to the engine mount holes before installing the rear subframe,
2) I tighten the front stud first (two 18mm nuts),
3) then install the telelever arm (the 18mm nuts for the front subframe are behind the telelever arm),
4) connect the front shock, and
5) install the lower triple tree, forks, wheel, etc. HINT: if the upper fork tubes (stancions) are really hard to slide into the handlebar mounts and upper triple tree, your lower triple tree is twisted/bent (ask me how I know this)
You also want to start locating the wiring harness and especially the primary ground on the top and back of the engine (under the battery tray) before you put the rear subframe on. You can still get it on with the rear subframe on but it can be a PITA if the battery tray is on. Also do not forget to route and install the clutch slave cylinder. Once the airbox/subframe is on, forget about it.
If you look close, you'll see that I've swapped out the wooden stand under the engine for a scissor jack stand (modified to bolt to the front lower lug on the engine case) and added stabilizing straps and ran the jack up against them. Solid mounting and room to work. You also might notice the white rag towards the back of the engine sump. I have another scissor jack there so it doesn't pivot backwards as I add the rear end.
Once the front wheel is in the vice, I install the rear subframe/airbox/fuel regulator/injectors, which can sometimes be easy peasy and sometimes a real PITA (such as this time). Nothing a block of wood and a 4 lbs sledge couldn't persuade (really). Also, don't forget to install the side stand before the rear subframe. If you forget to install the airbox/etc., you'll have to remove the rear subframe to install it (ask me how I know this). I install the big bolts first to hold it in place without falling, then the 2 long bolts and 1 stud on top that ties the rear subframe to the front subframe struts and engine. Perhaps this could be done another way but that's how I do them.
Also, I like to paint or powder coat the rear subframes red. An idea I ripped off of the Moto Guzzi Sport. My Tourer is candy apple red, this one is cheap engine paint, hence the orange hue. I should have had it powder coated fire engine red, next one. Really like how it looked, so...
