I use Carsons , they seem to prefer booking for ride in ride out ,so they have a tech available, always worth negotiating a price based on other qoutes,and they fitted to my xjr 1300 and my mates gsx1400, both had centre stands.
I know they have a multistand for bikes without a centre stand, if they have turned someone away maybe it was before they updated their stands........you can always take the wheels in loose as well
