I'll try to be brief, the vertical cylinder isn't turning...
This is my 3rd 2v valve adjustment, I feel relatively confident and things had been going smoothly. I measured everything and while they were all within Ducati's specs they weren't quite up to LT Snyder's, so I pulled all the shims to measure them and see if I could just do some simple swapping or sanding to bring the gaps where I wanted them. Again, everything going well, I was able to do some switcheroos, sand down one of them and one I'll need to replace. On to installing the shims, I started on the vertical cylinder, exhaust valve first, all good. On to the intake, as I'm installing the collets (what a freaking pain in the dick) on the closer a collet goes flying and I was pretty certain it jumped forward towards the center of the engine around the throttle bodies/air intake. I grab my magnet and fish around for a WHILE, no luck (I do have the valve chamber drain hole covered with a bolt...). So I move on, grab a spare collet and finish installing the closer, pop the opener on and go to turn the engine to reset the rocker. After a few spins I start getting more resistance than seems "right" so I do a quick once over. No obvious obstructions, so I give it a BIT more muscle and not unexpectedly I shear the weak ass nipples of the engine turning tool... Fuck.
So I pull the belts, horizontal cam spins as it should, vertical cams won't freaking budge. I reinstall the vertical cylinder belt, put the bike in 6th and give the wheel a try, it's really really tough to spin. Ok, get ready to cringe... I... uh... kind of go back and forth in a "whacking" motion with the wheel, giving it quite a bit of muscle reverse and forwards... I'M SORRY!!!
Well, that made bad sounds so I stopped...
Some noteables...
Yes the plugs were off
A very small amount of of oil was weeping out the horizontal cylinder exhaust valve chamber
A small amount of oil was weeping out the crank where I attach the engine turning tool
I can visualize the piston in the vertical chamber, it's not at TDC
All the valve seals appear fine
I'm assuming I need to pull that head? Please tell me there's an alternative!
