Title: B25 date
Post by: sidewaysid on 07 Oct, 2020, 08:44
I have acquired a pair of very clean crankcases for my B25 project, but when I go to order parts from Draganfly there are some variations in the model and year my cases are B25C 6031 can you tell me are they 1967/68 or are they 1969/70 it seems a lot of parts are different especially gearbox

Thanks

The cases are early1969 season (C for 1969) made in late 1968, the form of the numbers changed from November/December 1968.

My cases have what appear to be date stamped on them. On the top where the rear engine mount bolt goes through. Its something like 15 12 68. But the frame and engine number are for April 69.
