Hi Joe, Your problem is caused by unsynchronised carbs, make sure your fuel levels are identical and mixture screws are set identically before you synchronise the carbs at approx 1200 rpm, also make sure you have absolutely no vacuum leaks, cheers, Tadpole..
ps...I have a brand new 07 and let it be tillit had 1600 kms up and then did the job, now purfect.
