attakmod you could remove pin first and give that a try, or try o-s-o spring.

Wouldn't switching to a spring with such a lower finish rate cause it to shift out too much and keep it out of the sweet spot horsepowerwise?

what was the distance you were running?
attakmod said:I did some testing today.
g-force clutching-stock spring 105mph.
g-force clutching-hc spring 106mph.
super rats-hc spring 3gram ball + 1,5gram pin 106.
super rats-stock spring 3gram ball + 1,5gram pin 104.
super rats-hc spring 3gram ball 106mph.
super rats-stock spring 3gram ball 106mph.
Condictions were not great but as you can tell all the clutching changes made about the same mph, the only diffrence is the super rats pull "ALOT HARDER" then the ones from g-force, my favotite compo was the super rats with stock spring y-s-y it pulled just as good as the hc spring and got the same speed with out the engagement being to high.
The distance was anywere fron 600-700 feet, Condictions were not good, the g-force weights had the same setup as when I hit 130mph in 1/2 mile on speedo so that should tell you what it was like. yamadog1 I tryed with the pin and without the pin and with the stock and hc spring. with the hc spring, 1.5 garm pin and 3gram ball the engagement was very high but pulled the right rpms, with out the hc spring it only pulled 10,000rpm but engaugement was good and pulled to 104mph.

Best "spot on" clutching I've ever had. It revs up to 10,700 and then backs down to 10,200 or 10,300, then climbs slowly back to 10,800 or so. .
Just to let you know that's not spot on clutching. Spot on clutching on any sled takes you right to the power band out of the hole and holds there with maybe a slight climb of RPM's on top.
Nice cool clutches is a true representation of spot on clutching!!!

spot on clutching takes you to where peak torque & hp meet & let rpm,s slowly rise from there.
You wanna be 10-10,200 climbing slowly to 10,700+. done this once or twice before testing against other sleds.

"spot on clutching takes you to where peak torque & hp meet & let rpm,s slowly rise from there."
Torque = HP at 5252 rpm. Below 5252, torque is higher and above 5252 hp is higher.
When do torque and hp meet?

Peak torque is always lower then peak HP power. Torque is what moves you. So you want to come out on torque. HP is what pulls you on top. So you want your clutching to shot out to your peak torque rpm and then you want to let it climb into your peak Hp range.
One of the reasons four strokes are easier to clutch is they have wide power band. You don't have to try to hit a 200 to 300 rpm band.

I might swap out the black HC spring for the ysy spring as recommended. Attakmod also recommended this.
