Just bought a white spring, 90508-60007-00. I wouldn't call it white. It's totally black with a white dash on one coil. Is this normal? Just checking to make sure it is correct. Dealer says this is the strongest secondary spring available from Yamaha and what they use on sleds going out West to ride the slopes.
Yes the white dash is the marker and name of the spring. I thought the same thing and expected the spring to be white. The one you take off will be black also with a pink or other color on the spring. It is the way they grade their springs.

If in doubt, count the coils and measure the thickness of the wire. Thats the REAL determination.

You would have to take the offset into account this way also.

Not necessary, there are no two springs that differ by just offset, and if there were, you would just set a different degree of twist to make them identical.

What degree do you set this white spring at. Do you leave the front clutch stock? Thanks Guys. I just bought a 2006 apex rtx.

There are holes in the helix and sheave. Install the ends of the spring in the 3rd hole of each, known as 3/3 or a total of 6, then twist the helix just past the first ramp for engagement. I have done nothing with the primary, but for real close fine tuning Thundershift (FetBros) "Heavy Hitters" is a good choice.

Thank-you.
Thank-you.
As I'm still waiting for my first Yamaha, and have serviced Doo's for many years, I also have a question about servicing the secondary.
Do you need a "clutch dog" tool to disassemble it and change the spring on an Apex/Attak? Or is is pretty easy to do without any special tools? Doos are wound so tight and sometimes are so difficult to separate the halves, that a big clutch tool is very useful, but with skinned knuckles, sore forearms, using all three of my hands, a lot of banging with a heavy rubber mallet, and of couse an appropriate string of profanities, I could usually manage to change a spring & helix or reset the spring tension without buying the $100 tool.
I guess what I'm really wondering is whether Yami's secondarys are easier to service than Doos.
Thanks!

Working on Yammi's secondary is easier than SDoo.
No special tools needed.
