Help with decoding of YVX-secondary clutch parts... ??

Hi !

I need some help to decode some Yamaha part #'s for the YVX-secondary clutch

I need the angle of the helix and the colour and tension numbers of the springs.

Helix:
* 8BV-17604-11-00
* 8BV-17604-31-00
* 8BV-17604-50-00
* 8BV-17604-71-00
* 8BV-17604-91-00


Secondary spring:
* 90508-500B1-00
* 90508-536A9-00
* 90508-556A2-00
* 90508-556A7-00


Are there any spring tables ?
Are there any helix tables ?

...but obviously not all helixes !


Helix ( with straight angle )
* 8BV-17604-91-00 --> 39°
* 8BV-17604-11-00 --> 41°
* 8BV-17604-31-00 --> 43°
* 8BV-17604-50-00 --> 45°
* 8BV-17604-71-00 --> 47°


Where can I find a complete list of all OE Yamaha Helixes ?


Secondary spring ( Soft to Hard )
1. * 90508-500B1-00 --> BROWN
2. * 90508-536A9-00 --> RED
3. * 90508-556A2-00 --> GREEN
4. * 90508-556A7-00 --> SILVER

helix in question is 45*.

as far as where to find a complete list, the numbers change over the years and its best to have access to current yamaha publications, or easier yet to ask when in doubt.

1. How many Straight angled helixes is available from Yamaha ?
and what part #'s + angles ?

2. How many multi angled or proggresive angled helixes is available from Yamaha ?
and what part #'s + angles ?
