Does anyone know wich of the 2 main Oliver Tiger 15 (2.5cc) motors is the exact copy of the original MkIII ?
I have a MkIII that I have chesished for years, but it has had a repair to the crankcase.
I would like to replace the crankcase but am told the "CS" versions might have slightly different dimensions but the Australian ones might be correct ?
Or, on the other hand, does anyone know where I might be able to get an original O.T. crankcase
