I had made a post earlier about my disappointment with the torque spring. As is the case sometimes, it was operator error. I was not adjusting the variator weights, and when I installed the torque spring, my rpm were getting above the sweet spot. You have to adjust by putting heavier rollers in to compensate.
I installed rollers that would keep my rpm at slightly below 6K. Then, after installing the 1500 torque spring, my rpm would stay at a steady 7200. I compared this to rollers coupled with the stock spring that kept my rpm at the same 7200, and the 1500 torque spring gave better acceleration and hill climbing. The torque springs affect acceleration a little differently than rollers. This part is definitely an upgrade. If tweaked correctly, you can achieve noticeable performance upgrades with this relatively inexpensive part. I should have given this part more of a chance before I poo-poo'ed it earlier.
In my constant quest for 60mph out of a 139qmb, I stumbled upon the right setup for the torque spring that I had written off for dead. Next up, when I get the money, the high dollar performance clutch.

Doors your 1500 spring hang on deceleration?

I don't know what you mean by hang, but I haven't noticed any issues with it.

I don't know what you mean by hang, but I haven't noticed any issues with it. When you release the throttle, the clutch stays engaged until around the 1700 rpm range

played1.....That's exactly what it's supposed to do.

When you let off of the throttle, the engine doesn't go back to idle speed. It works exactly like the factory clutch, it just "shifts" you to a lower gear quicker on hills, and during acceleration. It works with the RPM very much like rollers. If your scoot runs at 6K RPM, installing the 1500 clutch spring will make your scoot hold steady at 7500. It affects acceleration and hill climbing better than just rollers, or sliders, IMO. Just get some heavier weights to accomodate the spring raising your RPM.
