Hi everyone,
so the "D" shaped mounting point of my centrifugal advance unit is damaged by a previous owner
obviously the end of the cam needs some clean up also
I see the part number as: 12 11 1 356 286
the bike is a 1971 R75/5
it looks like the factory changed the unit and part number around 1973 to a different style
I found something on the internet that stated the earlier plate had a quicker advance for better fuel, and that the later plate was preferred due to fuel quality....
hmmmm.. maybe?
I was thinking that I would find a new unit, that had a correct "D" shaped mounting point and try to clean up my mounting and hope for a better fit
I assumed I should buy the one for my year and the early characteristics.
but thought I would still ask... to see... if it is recommended to upgrade to a slower curve?
is that a recommended improvement?
thanks for everyone's time
