Basic Screaming Eagle Assembly
You may need to refer to the 'How To Build A Go Kart' page for further instructions for the rest of your build.
Attach Rear Swing Arm
Attach the swing arm to the rear of the main frame using 5/8" bolts. Hold the bolts in place with ni-lock nuts so that the arm can swing freely. At this time you can also mount the rear axle and tires, Be sure to put the brake disc and axle sprocket assemblies onto the axle loosely at this time.
You can now mount the rear shocks. The upper shock mount location is height adjustable. Be sure to use four 5/16" bolts on each side of this weldment for proper strength. There are multiple lower mounting locations on the swing arm for the shocks. The positions you use to mount your shocks will affect the ride height and stiffness of the kart to some degree. Note that the lower shock mount can be flipped around to fine tune the mounting location as the 2 sets of holes in it are offset. Example: using a lower shock mount location that is near to the swivel point where the swing arm and main frame attach to each other will make the shock compress more easily. Mounting the shock at a lower position on the upper mount will give you a higher ride height. You will probably need to make several adjustments to the locations you us to find what works best for you.
Install Front A-Arms
Now you can install the two front a-arms using 5/8" bolts with ni-lock nuts like you did for the rear swing arm. The front shocks mount in a similar way to the rear shocks. With the upper mounts being adjustable height wise and having multiple lower mounting locations. The mounting points in relation to ride height and softness will also be similar. Once you find the mounting points you wish to use you will need to adjust the angle of the spindle mount to adjust the tire toe out/in.
Mount Floor Pan
To mount the floor pan flip the frame over. Position the floor pan in your desired location, clamp securely, and center punch holes where you want to add bolts. IMPORTANT: If using a floor pan with a top and bottom side that is different be certain you have it upside down at this point. Drill holes through the floor pan and frame at the same time to be sure they will line up when done. Now remove the floor pan and flip the frame over, and bolt the floor pan on.
