secondary spring

[Doowithblue]

Which vendor is working on an updated spring? Has anyone looked at this one? SLP 167-4078?
Falls between cat red/white and yellow. 4 coils.

Ulmer has a new spring available on his website, helix as well to upgrade his clutch kit.

So does the older cat torsional fit our SW? Is the diameter the same?

What is the stock SW secondary torsional rates?

Doesn't look like he's selling it by itself. I'm VERY interested in how this spring differs from stock.

fit my clutch with a dalton helix nicely

The million dollar question is: has anyone found an overall better setup out back that doesn't sacrifice top end but delivers improved holeshot and corner to corner? Where is this magical spring? Winter is almost done and we still have a secondary that is weak at best.

I'll ride stock this year and wait it out until we have plenty of feedback.

I have a XYZ secondary spring coming should be here in next few days. Unfortunately I already have. Left and at cabin for five days. 180 in today. But I will post pics and thoughts as soon as I get spring. Suppose to be stiffer then stock an also 1 less coil. Not a 100 until I get it and compare to stocker.

They just use everyday dalton stuff

I remember back in 2001 doo came out with a white stiffer secondary spring and it lost top end. Everyone put the good Ole beige back in at 19lbs and got all their speed back. Maybe terry is on to something? Would a slightly weaker spring wound tighter be the ticket? Yamaha white?
