On the FD boot there should be NO oil leaking out of that dust boot. It is designed to keep dust out not hold leaking oil. There is no groove for the rear end of the boot to seal into.
You do need to hold the speed bleeder up high, but I agree it is pretty easy to use other than being a little slow to empty it out for re-use.
Yes, I realize the FD should not leak, but it does. A $21,000 motorcycle shouldn't leak at all, but I've only had two vehicles that leaked more than my LT. A 1971 Beetle and a 1979 Chevette, and both had 50,000 miles before the leaks got as bad as my LT is at 27,000 miles.
My LT is leaking oil from at least two places and possibly three. I am losing oil under the "bell housing" so either the rear main is leaking or the front transmission seal is leaking. And the leak at the FD boot means either the pinion seal is leaking or the output seal on the tranny is leaking. I just checked the transmission and FD oil levels and the tranny appears to not have dropped at all in 2,000 miles so I am not sure it is leaking. The FD also appears to have not dropped much, but it is harder to tell as the level was 10mm or so below the fill hole (see below) at the start so a slight drop is harder to see. The tranny started to slowly leak out the fill oil so its level is right where it was when I changed oil 2K miles ago. The engine loses a quart every 5K miles or so, but I have no idea where the oil is going. Could be a combination of leakage and some burning.
I am a long-time fan of synthetic oils, having used Delvac/Mobil 1 oils since 1977 or so. However, both leaks on my LT started after the dealer put in synthetic oils at the 12,000 mile service. After consulting with Tom Cutter, I went back to Castrol dino oils and filled the FD with only 220 cc rather than the 250 or so called out in the BMW manual. He said that he has had many leaks go away after making these two changes. I only have 2,000 miles since making the switch, but the leaks still persist. I think they may be slowing somewhat, but have not gone away by any stretch.
I was hoping to clamp the boot better so I could keep the oil inside and just release it every 500 miles or so by loosening the clamp. That way my LT wouldn't look like an AMF Harley all of the time!!
You'd think for the price BMW charges, they could make bikes that don't puke gas (QDs) and oils, but apparently not.
I may pull the FD for a pre-emptive rebuild next winter, but really don't want to do that now just as the riding season is commencing.
