I personally prefer Amsoil over Mobil1 - I used Mobil1 V-twin for about 1500 miles (1 1/2 years), then switched to Amsoil - I *think* overall it's a little smoother.
But, FWIW - I still use Mobil1 in my wife's Touareg and my M3 with no issues.
As others have stated - any synthetic is great for an oil change, then if you'd like, change your flavor for your next one and see if your bike likes it better.
And of course, follow Lesley's advice - no torquing the drain plugs!
