Dear Johhny Jeez,
I apologise if I came across as tarring every biker with the same brush, but it was not my intention. As in my previous post, I have observed bikers stopping before the ASL, even when it's empty.
My primary concern about motorbikes in the ASL can be illustrated by watching the scooter rider in this video;

I have had this experience with bigger motorbikes, especially on my commute to work in Bristol which goes past a certain well-known large motorbike showroom (Bristol cyclists will know where I mean). Maybe the vicinity of the showroom skews my experience in the ASL due to the increase in the number of motorbikes in the locality.
However, I'd like people in london who read this thread to do a little experiment. On your commute, just stop for 5 mins at an ASL near you. Observe how many motorbikes stop before it on red or just enter into it. I think you'll all be surprised at how many motorbikes fail to stop and it seems to be a cross-section of those on PTW's ranging from scooters to the big machines. I don't think it's a hardcore of people, just general ignorance of the Highway Code. It is also not tarring alw-abiding bikers, just simple observation of what is happening in reality.
There was a few years back an experiment run by the Dept of Transport which looked at the possibility of allowing PTW's into the ASL at some junctions but I believe it concluded that it wasn't a good idea due to the size of some motorbikes.
I don't think PTW's should be allowed into the ASL for the very simple reason is that it encourages others (rather like pavement parking by drivers) and the last thing that cycling needs is the ASL's to be blocked by motorbikes. This is especially important in London where cycling seems to be booming at present.
Finally, the original post did ask for people's experiences with PTW's. Some, but not all, of mine just happen to be a bit negative.
