I do not know much when it comes to clutching. I was talking to gentleman whose whole family runs srx's. He said that the bender racing secondary would max out at 100 mph. Would get up and going fast but never more than 100mph. I was wondering if I should leave what I have or find a stock clutch to get a few more mph. I'll add some pictures. Mabey he is wrong or had bad set ups in the past. Also how can I tell which bender set up I have? Also should mention my speedo is not working as im to lazy to pull the drive and replace the insert in the drive.

the number of the helix or code of it is engraved inside the helix, you have to remove it to read the code, for example 9870, which would mean 1998, 700, snowmobile.

Thank you. Darn more work 
. Do you think it would reduce top speed by 10 or more mph.

How warm are your clutches? RPM's? But the wrong helix will slow you down. Not sure about how much. Need to know the angles. And you need to know what's in the front clutch for weights.

Typically on a Bender helix, TP indicates triple pipes.
