I have bought a cat 3 damaged 998 with all paperwork from a dealer with a VNC check. The engine does not have a number on the side. The frame is a 998 with the correct numbers on the headstock. My problem is when I went to change the oil I found out it has a deep sump engine. That must mean that it has a 996R or 998S engine in it.
How do I identify if it has a 996R or 998S engine in it ?
The CPU says 996R on it but I do not know how to identify if it is a proper R engine.
Not conclusive, but try Ducati UK with the frame number and they should tell you what it "should be". The 996R ECU was fitted to a few 998's when they got Termi cans fitted. Only real way to be sure would be to pull it apart and see what's inside, cam spec's, Ti rods etc.
I guess there's no plate on the headstock so that would tend to indicate it's not a 996R although there are some without. The simple answer is to email the engine, frame and registration numbers to: info@ducatiuk.com and they will give you the bike's history.
Do you have a carbon air box? Do you have ohlins front? is it a bp or mono? The cam numbers will tell you as they make quite a difference on the power output 998 or a 998S!
