RS Venture TF Secondary Spring settings

[Yammi-Rider]

Can someone tell me what the stock spring setting should be on a 2005 RS Venture TF. I had my secondary apart last night for cleaning and it popped open and the spring fell out before I could check the settings.

The inside sheve has 1, 2 and 3 markings. I know where the outside sheve was because I marked it before I attempted to separate the two sheves.

The spec sections says 70 degrees. How do you determine 70 degrees?

I cut and pasted this from the TY Tech forum...hope it helps!

To change the secondary spring and helix it is easiest to do this on the snowmobile. Lock the parking break, take a 12mm ratchet and remove the 3 nuts on the end of the helix posts but push in slightly on helix evenly to preload secondary spring. Once the helix is removed, there are 3 holes on the sheave that the secondary spring goes into. Those holes, in combination with the helix holes, when using Yamaha springs, will give you the degree of twist. For example, sheave hole #2 and helix hole #6, 6+2=8x10=80 degrees using Yamaha std springs. This will change with the use of other then Yamaha springs due to the spring ends starting at different places. When you put the new helix and spring back in, once you have found your degree of twist, you will have to slightly twist the helix so the ramps line up with the buttons and the holes line up with the studs on the sheave. Stiffer secondary springs will require more twist force to line up properly. Secondary clutch center main bolt will not have to be removed to do this procedure.

6-1 would be 70 the helix should be numbered too 3-6-9 and the clutch 1-2-3 so 6-1is 70

Thanks for the responses guys. I guessed right when I put it back together. Nice to know it's back where it belongs.
