What elevation?
Hi,
You did not specify what el. you were wanting to run them at.
Mine orig. had psi twins setup for about 6500 ft.
Mains- 151
Needles in 2nd position
Primary spring- 3, 30, I don't re. the color.
Arms- Weights- no rivets.
Shiftout- about 8400 rpm. ( too much in my opinion) so adding some weigh to the arms would be good.
Cheers
