2000 Secondary Clutch Helix part number?

[snocrazy_web]

Hello.

I have in my possession 2 Yamaha secondary clutch helixes.
Both of them have different part numbers.
One of them I think is for the SRX and the other is for a Viper.

Here are the numbers on the outside of the helix.
8BV51
8BV31

Does any one know which is the stock one for the 2000 SRX?

Thanks.

please note that the numbers listed are not the yamaha part numbers. They are the numbers stamped in to the part.

Thanks.

Looks like snow tonight in the Chicago area!
