Rd400 engine rubber mount rear

[rd400greenhorn]

Yeah so iam seriously in doubt..
Many engine i have seen have the 2 small rubber bushings
in here

But what is it?
I believe i have seen this in haynes manual but also means i have one big rubber mount in spare from the Kit 🤔

[stresa]

One big rubber mount is enough 😉
That's a fault even in the Yamaha parts list which also shows 2. And Haynes and the replica producers took this fault over....
