Yeah I figured, I will just have to see how it takes off. I still have the SS clutch and spring witch I think is an 8k spring. Not looking to launch it hard and in sand that hard engagement can spin the tires too fast and get you stuck.Change to preference. You probably know but I'll say anyways, the number of clutch spring, such as 6000, means it will engage the clutch at 6000 rpm. 8000 will engage at 8000 rpm, and so on. So the later the engagement the harder the launch.
