Got my S4 back on the road today, its been fitted with SPS cams by Ducati John, seems a top job.
Only taken it 6000 rpm so far as I need to make sure the fueling is correct by taking it to a dyno centre but the cams so far seem a good investment, thought they may have screwed up the bottom end torque, not at all, its smoother and the induction noise is wonderful now!
