You will need wrenches or sockets suitable for the bolts on your pit bike, and possibly a drill for modifications.
Yes, but you may need to modify the tensioners by drilling out the axle hole to the appropriate size.
The chain should have about 1/2 to 1 inch of play when measured midway between the sprockets.
Check the chain tension regularly, especially after aggressive riding or if you notice any unusual chain noise.
CNC machining ensures higher precision and durability compared to standard manufacturing methods.
The tensioners are made of Alloy CNC.
The thread length is 41 mm (1.61 inches).
Adjust the tensioners to apply more pressure on the chain. Ensure the wheel is correctly aligned.
Loosen the tensioners slightly until the chain has the proper amount of slack (typically 1/2 to 1 inch of play).
Ensure all bolts are tightened securely. Check for any stripped threads.
These tensioners are designed for 50cc, 110cc, 125cc, and 140cc pit bikes with 12mm axles. If your bike has a different axle size, you may need to modify the tensioners by drilling out the axle hole.
