First time I've heard about this "decompressor" system, but sounds more like the culprit for the starting issue. Seeing how the 899, 1199, and 1299 (from a quick search) all have starting problems and also have the decompressor system, kinda surprised no one's suspected it yet.Ride Apart said:One interesting system bundled into the 959 Panigale is the “Decompressor” engine starting aid. This system modifies cam lift during engine startup in order to keep valves slightly open, reducing combustion chamber compression. This reduces load on the starter motor and battery, in turn reducing the required size of each. This results in an impressive 7.3lbs vehicle mass savings. However, it must be noted that on one occasion, the engine flooded and took several minutes to finally fire up under a cold-start condition. The root cause of this fault was not determined, but it’s hard to ignore the possibility of this decompressor system acting as a contributing factor.
