Our Custom Engine shop is capable of producing some of the most powerful Harley rebuilds in the area. We do custom head work, boring big inch machines and stroker motors. From stock builds to radical V-Twins, trust your performance needs to Lawrence's. We also are one of the only shops in the USA that still works on Flatheads, Knuckleheads, and Panheads. We not only work on them, were experienced with them, and have been doing them for over 30 years. Call Lucky for a quote 1-208-664-8032 (shipping available)

This is our Milling Machine. We use it primarily for our custom Head work and the fabrication of vintage parts. Note: Valve Seats cut  with Sunnen tooling.
We do all of our cylinder boring & honing  in-house. You can also see we have a metal lathe for fabrication of restoration parts on antique bikes. Notice the Sunnen LBB-1660, it precision machines tappet blocks, Cylinders, Rods, Valve Guides, and Panhead rocker boxes. We also use it to line hone cases.

Big boring some Shovelhead cases with our Quick-Way boring bar, don't you love the sound of a big inch Shovelhead. 

Finishing up on some cylinders. Did you know that a deviation of 1/3rd the diameter of a human hair can cause premature ring and piston wear. The maximum tolerances allowed at our shop is .0002 or 15 times smaller than a human hair. 

Heads getting a work out. Did you know that more than .002 runout in a valve seat can cause valve or guide failure. It causes heat buildup and can reduce the effective pressure a valve can handle by over 4 times. 75% of the heat is dissipated from the valve seat (concentric seats are a must). We keep our runout at .0005 or half of a thousandth. 

Restored 45 cases, just like new (or maybe even better).

The view of a finely finished cylinder, how big do you think this bore is?
