So I just bought a used 2003 999 with 10000 miles on it. It has an upgraded evoltione slipper clutch other than that it is all stock. If I speed up let's say around 40 or faster and I pull in the clutch and slam on the brakes ( to maybe avoid something ) it stalls. That is the only time it ever stalls. It is fine at stop lights and never even sounds like it is going to stall. I dont know if this is a default in the manufacturing or maybe something with this new clutch. Just wanted to see if anyone has had this happen to them.
