My dealer grabbed the spec off of the Attak by accident and put the secondary spring back in at 60 degrees instead of the 70 from the factory.
I saw speeds on the speedo 8 MPH higher then I have ever seen. I was also on very hard pack with a newly installed predator 1.25" track.
I was told I would notice a little difference down low (a little slower) and would reach top end quicker and possibly even gain some on top.
What do you think about this setup? Should I go back to the factory settings?

i think the factory setting for the attak is white secondary at 3-3 (60), the apex comes with a pink spring at 6-1 (70). also, the apex has a 24 top gear and the attak has a 23, the apex's have been putting in the 23 top or 40 bottom and using the white spring at 3-3 (60) and have been seeing alot of gain with that, i haven't heard of the attak at 6-1 (70)

What do you think of the Yammi white sec. spring? I was thinking of getting it for my 07 to see what gain I would get over stock. Should be at 3-3 correct?

You are correct.
I have an Apex ER. What I am saying is he grabbed the degrees from the spec sheet for the Attak instead of the Apex and wound the spring to 60.
Anyone else have any thoughts on this?

sorry, misunderstood, if you have the pink spring in and he put it to 3-3 (60), wouldn't it lower your rpm's a bit?

That is ok. It did lower my rpms. Which I am ok with as I was hitting 11k. Now I am down to about 10,800.
My concern is I have no idea what it is doing to my performance as I do not have a stock Apex to compare it to.
The white spring will slow down an apex. It has more side force on the secondary. What that does is slow the upshift on the driven. It is like driving on the hiway with your car allways in ist or 2nd gear & not using 3rd or overdrive. Gearing down will worsen the effect of the white secondary spring. the attack needs the white secondary spring with stock clutching because when it hooks up with the added track length it will suck the belt down into the secondary & drop rpm,s. No way no how in a skazillion years will an apex be faster on top or acceleration wise using the white secondary spring with stock clutching. Raise a sled that is close in acceleration 3 times using each secondary set up & it,s gotta be same day same conditions & you will see.

I am sorry if I was not clear on this let me lay it out again:
I have a 2006 Apex ER
I have the stock spring in it. (Pink)
The spring was wound to 60 degrees instead of the 70 degrees stock setting
Your letting the sled upshift faster by loosening the secondary wrap & as long as the belt ain,t slipping in the secondary it,s all goosd & sled should have better acceleration. Hopefully tho i cleared up some misconceptions on using the white secondary spring in the short tracks tho.

Turk: i don't understand, i was told if you change the top gear on the apex to 23 and use the white spring at 60 twist you would gain top end, i have an attak and use the white spring with the ulmer stage 2 kit, would i be better off using the pink spring for top end gain?

What about trying the stock Pink at 6-2? Thanks for the great advice on the White spring, didn't purchase it yet!Turk said:
Shark; explain to me how using a stiffer secondary spring that holds the shift back is gonna make your sled faster with more top end? Pick & choose your info on here carefully. There is some advice that I just don,t agree with. This is one of em along with using washers when mounting your helix on the secondary clutch.

Turk said:
you misunderstood me, i was asking you if it would be better to use the pink spring on the attak instead of the white spring, i would like to get more top end out of the attak, what is you opinion?
Everyone has there opinions. If you are studded, the white spring works excellent. Pretty sure Turk isnt running any studs up there. That said, I tested 3 different secondary springs on my Apex, all within 1 hour at a radar run. I had 5 runs of over 120. My best top end run was with the white spring at 60 degrees. Other mods have been done, but im here to tell you the numbers dont lie. Secondary is opening up all the way and primary is closing all the way. If the white spring didnt work, your wear lines would indicate you are not fully shifted. My primary has been machined as well as helix so it is much easier for me to determine how far the primary is shifting...BBY
Also, conditions such as Turk rides in would be no place for that white spring, so I am agreeing and disagreeing with what Mike says...BBY
