Hey All

Having a read on the forum and I have a couple of questions I’ve not been able to find the answers too..

Looking at the H1 H2 & J (SP) models I note that the SP engines are stamped with a J on the RHS below the heads..

Are there specific engine & Frame numbers for these
models?
Do the H1/H2 have another letter stamped on the motor?

My RD350LC are model specific with 4L1 (250) and 4L0 (350)
