I'd have to agree with amb here - time to take it to a service centre (aprilia being the preferable one) as they may be able to diagnose it straight off - maybe give thier service guy a ring and tell him your symptoms and he may be able to tell you off the bat or say don't start it again. Call Griff at Aprilia Peformance he's a very knowledgeable guy.
