Decoding of the YVX secondary clutch parts... ?

[Lasse]

Hi !

I need some help to decode some Yamaha part #'s for the YVX-secondary ( 1995 ---> ) clutch

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

Helix:
* 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°


* 8BV-17604-10-00 ---> ??°
* 8BV-17604-30-00 ---> ??°
* 8BV-17604-70-00 ---> ??°
* 8BV-17604-90-00 ---> ??°



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


Are there any driven spring charts with tension numbers ?
Are there any helix charts ?

Had a chart saved for the springs, but can't find those part numbers for the missing helixes listed in my saved notes or Aaen tuning book.
