What kind of results are you wanting to hear? It's internal upgrades. Pretty self explanatory.

I would like to hear more about the installation of this kit as I am going to upgrade one day soon.
Sounds like removing the drive coupler is a bitch.

Removing the drive coupler would be the least of my worries. You don't just slap pistons and rods in the block. The block will need machine work, you will need to know how to file fit rings, check clearances, install pistons, and torque rod bolts. Unless you feel very confident in these processes, it would be best to let RIVA assemble the shortblock. I would also caution against just using some random machine shop who does not have experience with SHO motors.

Does the intermediary shaft have to be removed to get off the magneto housing?

Yes, and the OEM tools to do it properly are about $500-$600
You can get the big ass coupler wrench from R&D and save a little money.
Well, before I was so rudely interrupted by the site not responding at all... Again...
This is the generator with the transfer shaft still installed
These are the tools except for the one you need for the transfer shaft

I did not remove the intermediate shaft and magneto housing when I rebuilt my engine last spring. These components are better left on the crankshaft if there is no particular reason to remove them. All machining and balancing work can be done with these components assembled on the crankshaft.
Doing a good rebuild takes good knowledge, time and proper equipment. It is not out of reach for people who have reasonnable experience at building performance engines. However, the fact many aftermarket parts are typically installed in a performance engine rebuild makes the whole thing much more complicated.... never assume all aftermarket parts out there are better than genuine Yamaha parts. There are many performance parts that don't mix well with one another...... and that can ruin an expensive engine build quite fast.
