Harley Davidson Motorcycle Thread Repair

Eric Grafton at Jerry’s Broken Drill & Tap repairs the thread of a Harley-Davidson Motor Headbolt using a BigSert Oversized Time-Cert Thread Repair Kit. The wrong thread repair kit was originally used creating and over-sized head bolt hole. The Harley thread repair was a success after careful rework and using an over size big cert thread insert.

I love anything to do with Harley Davidson and have two beautiful children and a beautiful partner. In my spare time i like building websites and love anything to do with the internet.


  1. this guy definitely doesn't know how to use a tap because you always back the tap out as you're working the tap in to keep the threads clean and keep the tab from binding

  2. Thanks for vid. Question-When you clean out with the air, the shavings are still in the case to be circulated. Wouldn't you want those shavings out of case? Vacuum maybe?
