I'm certain I'm going to raise someone's blood pressure with this one.

 

Don't let the metal blanking plate/ disc jump out of your angle drives. Perhaps made more likely by adding viscous lubricant to the housing . . .

   Back to work...Throttle body day

Thanks to Lucky Phil's thread [ link ] this is easy enough for anyone to do at home. 
I didn't think to take a lot of pictures before starting, but the bottom of the throttle shafts were DEEP with what looked like the bottom of a '74 Ford 460 oil pan. 
My throttle blade screws weren't peened or center punched, they had simply been hit once with a chisel, looked like; turning them out was easy enough probably could have without damaging anything. I used a set of duckbill pliers to squeeze the end together a bit while not flattening the threads. Came out surprisingly easy though probably won't go in as well. Certainly going to touch them with loctite going back, may try new screws if the hardware has the correct pitch in brass. 
Went to the very back of the 'special tools' drawer and drug out a 5/16" valve guide driver (8mm) a perfect fit for the bushings. Easy to feel when centered, a couple medium whacks and when the seal shoulder stopped, stuck the old bushing on to drive the new ones home to the shoulder. Easy peasy.
The old seals were so dead they actually fell out as I pulled the shaft. 
Finish tomorrow, everything soaking in Boraxo/dishsoap to soften the road armor covering the linkage arms and TB bodies. 

Upside-damn-down again, WTF 

Turn your head lol

My bolts on the main shaft was hit by something big. Had to grind to get the bolts out. Grinding the shaft flat does a thing with the airflow, a smart German guy mentioned. 1 Very stubborn bushing to remove, otherwise wise not hard. It’s a Guzzi l know, but l like them best possible tuned. Did you use Yamaha seals or. 
Cheers Tom.

I was very surprised to find the screws so lightly secured. I'll try to remember to photo the other TB. The bushings came out fairly easily, a 9mm tap halfway in and a punch from the other side. The new ones seemed a bit tighter in the bores, but not enough for concern. Only the one bushing on the bottom RH side showed any perceptible wear, but I have them and I'm there. The seals were the big shock, they were loose on the shaft and in the bores. I used the *very* expensive ones listed in Lucky Phil's thread, iirc they're about $12 each. I searched for a couple hours and found zero else available, I could have put together 2-3 purchases of old Yamaha stock but these are viton and should last the life.
