AMA Pro Racing announced today that Mat Mladin has been disqualified from the August 16-17, 2008 AMA Superbike Championship presented by Parts Unlimited round at Virginia International Raceway following the outcome of post-race technical inspections.
The crankshaft from the #6 Rockstar Makita Suzuki was sent to AMA headquarters in Pickerington, Ohio, and was compared to other production crankshafts from the same model. Upon this inspection, the crankshaft was found to be in non-compliance of the 2008 AMA Superbike Championship Rulebook.

Superbike, 2.4 Crankshaft
Only the homologated crankshaft is permitted with the following modifications:
