the gear in question is the center gear. gear on left is a known 13w 42t hyvo, center gear is 13w 40t ?, gear on right is a known 15w 40t non hyvo. I'm thinking the center gear is a non-hyvo looking at the teeth but would like some confirmation.

THESE GUYS ARE RIGHT ON. THESE GEARS WERE THE HOT SET-UP ON THE 98-99 SRX FOR RACING. 3:16 (yammie tony)
Can somone explain (maybe with pics) the difference between hyvo and non?
This shows the chain, but what about the gears?

the pics in this post show the differance, the gear on the left is the hyvo gear, note is has a rounded tip and the valley of the gear is also more rounded.
The other 2 gears in the pic , center and right one are std silent chain, they have a pointed tip and more of a "V" in the valley of the gear.
