I just find it easier to take the seat off and screw in an eyebolt, rig it, lay it over and do the clutch or whatever in there. I've done 2 Speedys 3 Americas, 1 Bonny and 1 Thruxton, all clutch spring jobs. I'm a popular dude around here in the little local Triumph pack that hooks up on the 3rd Saturday of the month. Having a lift, a warm shop and all the tools, probably doesn't hurt either. You are right though, drain it and reuse it, or add a cup when your done, all the same to me. But with the bike layed over, I don't have to crook my neck so far. Even the wavy washer stays put when I pull the cover. I lost one the first time, never did figure out where that sucker went.
