2023 is the last year I will produce PORTED big bore kits with my own two hands.
I will continue to sell and market my custom pistons and gaskets and manufactured cylinders.
Starting January 1, 2023 you need to call or text for an appointment because I have limited space
in my workshop. No more sending engines without paperwork or a clear ability to pay for the work.

Welding Services

Eric Gorr here. Shawn the welder is the most prolific welder in the sport of motorcycling.
Shawn has welded all of the cylinders and crankcases sent to me since 2008.
In addition to that Shawn was the manager of the welding and boring department at Millennium
and he welded tens of thousands of cylinders since 2000. I'm helping Shawn start a new venture
welding crankcases, covers, heads, and crankshafts.

Shawn the welder is the best kept secret in the motorcycle industry, and now he works for you!

Here is a list of all the things Shawn specializes in, and I set up an order form (coming soon) so you can
direct work to Shawn through my shop address.

  • Typical Engine Damage And Repair Cost Scenarios
    Shawn the welder offers services bundled together with clean and prep, welding, and machining.
    Here are the popular examples. You can always text Shawn a picture of the damage and get a fast quote!
  • Exploded Piston Damage To Cases
    When the piston explodes the framents can become wedged between the crank and cases and bust-out the case.
    Shawn welds and trims and mills the cases flat so they seal well. Starting at $100
  • Derailed Chain
    If the chain derails it can smash the guard and break or groove the cases. Shawn can weld the damage,
    sculpt and polish the weld and re-drill the mounting holes for the guard. Send a new guard for alignment.
    Prices start at $100
  • Stripped Drain Plug
    Often times the drain plug gets stripped from over tightening. Shawn welds up the damage with a wider margin
    so the plugs hole is stronger and resists stripping. Starting at $50
  • Gearbox Damage From Fragged Gears
    When gears break apart they can cause damage to bearing porckets and the outer cases.
    Shawn welds and sculps the damage so it clears the whirling gears. Starting at $50
  • Rock And Collision Damage
    Rocks and logs can destroy cases and covers. Shawn can weld and polish the chips and nicks.
    Another common problem is worn engine mounts. Shawn can weld, surface, and remachine th engine mounting hole.

  • Kickstart Backfire Damage
    When a big bike kicks back it can break the lug in the case. Shawn can repair the crankcase and the cover,
    and even relocate and weld the starter lug on Yamaha kickers! Starting at $100
    Shawn also offers compression releases to the cylinder head to help prevent kick back and backfires
  • Custom Compression Release Installation
    Shawn offers a variety of compression release mods for different applications.
    The most common is a KPM decompression button that gets welded and machinind in the original cylinder head.
    The cost is just $125 for air cooled bikes and $150 for watercooled bikes 250-550cc 2-strokes.
    This kit includes bead-blast cleaning, welding, machining, threading, surface facing, and 1 - KPM button.
    Replacement decompression buttons are $30 each.
    Another custom option is a lever operated compression release that is often used as an engine brake
    and is popular in Vintage dirt track and enduro racing. The machining labor starts at $75 for air cooled bikes.
  • Precious Antique Or Discontinued Parts Repair
    If you have a precious antique dirt bike or a discontinued part that is damaged, then Shawn can save that
    expensive part and make it like new. Welding of aluminum, magnesium, and cast iron is possible and based
    on the job description. Shawn has a special program for dealing with museums and large scale collectors.
