Frequently Asked Questions

Q: What is the recommended torque for this starter bracket screw?

A: This screw is designed to be torqued to 20 ft-lbs. Using a calibrated torque wrench ensures the bracket is held securely without stripping the threads.

Q: Why is a Grade 8 screw necessary for this application?

A: Racing karts, particularly those using the World Formula engine, generate significant high-frequency vibrations. Grade 8 steel provides the high tensile strength required to prevent the fastener from snapping or loosening under these harsh conditions.

Q: Can I use a standard hardware store bolt instead of this specific screw?

A: We strongly recommend using the OEM-specified fastener. This screw features specific thread pitch and head design engineered to grip the starter mount firmly and resist back-out, which is critical for maintaining pull system alignment during high-RPM starts.

Q: How often should I check the tightness of my starter bracket hardware?

A: As part of your pre-race maintenance routine, you should inspect all engine-mounted hardware. Given the vibration levels of racing engines, checking your starter bracket bolts before every race day is a best practice to ensure reliability.
