91 750 Rear head removal

In the 91 service manual it indicates that the front head can be removed with out pulling the engine but not the rear. Wondering if anyone out there has proved this wrong and if so how they did it. I have a stripped spark plug hole in cylinder 1 (back left). I have a replacement head and gasket enroute. would like to do this as painlessly as possible, specially to the pocket book. I've never worked on the heads of an engine before how ever i did split the lower case on my maxim 2 years ago to fix an issue with a primary chain guide that shattered. That was an experience and a nightmare.

 

I just looked at Cundallini's bike and it looks like there is plenty of room to pull the rear head off, I was suprised how much extra room there was. I would try it myself, let us know.

 

I am going to poke around and see if this is possible and how much more of a pain either pulling the engine or pulling just the head will do.

I looked into it, a shop will charge me $200 to helicoil with the engine in the bike. looking at 400-500 for them to pull the head and helicoil it. I have a new to me head en-route and I may as well just do it right the first time. Shop won't guaranty their work with the helicoil... I've also looked at other inserts such as timesert and Spark Plug Thread Repair Inserts

 

Well I decided to follow the service manual... they claim the rear can not be removed, so I got started removing things like the seat (duh), the tank (that's an easy job how ever the off switch isn't 100% off), the airbox, the plastics (I think a naked version of the bike would be nicer for working on), drained the oil and removed the filter. That all took me a about 3-3.5 hours, being a used bike there's a few oddities like i don't think there's supposed to be expanding foam holding in the signals and I'm doubting honda used a couple robertson bolts on the plastics.

next i've got the radiator, disconnect the oil cooler, exhaust, carbs and i dunno what else.
