OK, this is not about motorcycles, well to some extent it is.
My Jeep transmission - Borg Warner WC T5 - kicked the bucket at 300 000 miles and yesterday I bought New Process 435 from this old timer in MD. It will take Novak's adapter to marry it to Dana 300 but the final solution will outlast me.
With the old timer we talked jeeps first - he had two CJs parked in his yard, together with a mix of other vehicles - but when I mentioned old Yamaha he had there too - just frame and engine, we got to motorcycles and sure enough, he has 1975 CB750f, parked since who knows when, next to it HD that was produced only a year or two, his daily rider was a small newish HD, he has 2007 Honda CBR900RR for the need-for-speed moments and he is fixing 1976 Moto Morini.
Oh, I forgot 2 stroke Yamaha in the shop.
Nothing beats talking vehicles with an old timer.
