What engine number did the larger (19mm) capacity oil pumps come in? My K2 engine has a 16mm pump and I'm wondering how many people are still running the earlier 16mm pumps.

Also, I've been looking for the service bulletin on the subject, but with no luck. Can anyone post a copy or send it to me?

I think it happened at K3......

my SL350K2 has the 19mm oil pump, and it is original.

The later 350's shared the same part.....

Should I be concerned that my bike has a 16mm pump? I'm guessing there must be quite a few bikes out there running these without problems.
