Can't help ya on the spring but if my memory is correct the helixs are 10 = 41, 30 = 43, 50 = 45 and so on.

Those springs that you wrote down are under Secondary & alignment spec in the Clutching and Jetting section.

If my memory is correct the helixs are:
# 10 = 41°
# 30 = 43°
# 50 = 45°
# 70 = 47°
# 90 = 49°

Anyone who can confirm this ?

My appolgies. I did not READ it .. I feel like a real dumb azz now. Sorry. I assumed that were the same I have not seen these numbers before. The tech manuals only ref secondary springs and cam angles with the number in those charts. Where did you find them?

# 70 = 47°
# 90 = 39°

Helix:
* 8BV-17604-90-00 = 39°
* 8BV-17604-10-00 = 41°
* 8BV-17604-30-00 = 43°
* 8BV-17604-50-00 = 45°
* 8BV-17604-70-00 = 47°

90=39
10=41
30=43
50=45
70=47
I believe that if there is not a zero(but probably a 1 in its place) it is one of the following:
1. A revision.
2. A second production run.
3. A design change.
IE.....a 31 is still a 43*.
