My RSV4 RF had exactly the same problem in Almeria , It arrived back in the UK on Saturday , dropped it at Aprilia Performance in Tamworth Saturday afternoon , Griff got onto it first thing yesterday , called me yesterday to say it was sorted , it ended up being a loose wire on a MAP sensor connector block. All sorted , No charge > Excellent service from Griff and his team at Aprilia Performance Centre. I was going to pick it up today , but my fuckin van packed up.
