Testing CVT Springs for Speed – Then THIS Happened…
2 slow 2 stroke
37,599 views
In this video, we test the performance of different CVT contra torque springs using a method you can try at home — with nothing more than a bathroom scale.
I compare stiffness across several springs, install each one, and hit the road to see which setup delivers the best performance. But it wouldn’t be a 2Slow2Stroke video without some serious drama — including breakdowns, missing exhaust bolts, and an unexpected roadside repair.
Whether you're chasing max speed, snappier acceleration, or just learning how to dial in your moped’s CVT system, this one’s packed with useful insight (and chaos).

Torque Wrench is for tightening screws, bolts and nuts.
The result is very amazing
