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

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?
Here: https://www.shopyamaha.com/parts-catalog/lines/snowmobiles?nw=yamaha-motor-company
( 1996 - 1999 ) Phazer-II 480 Mountain Lite
( 1995 - 1996 ) V-Max 500 & 600
That just take me to the online parts order. Can you link me direct to a page?
# 10 = 41°
# 30 = 43°
# 50 = 45°
# 70 = 47°
# 90 = 39°
I looked in the 99 Tech Book, one of them was wrong.. the -90.
MrSled 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*.
10=41
30=43
