General Air - Call them up and ask. I took some classes from them after purchasing a mid-end 220v Lincoln wire feed, and it was all I needed for steel welding. The motor mounts I built from that teaching are handling 250hp/700 lb/ft torque (cummins) after 5 years and 20K miles in an old Ford pickup. I took the class in Colorado Springs, but they are all up and down the front range. If they don't teach bike frame specific welding (lighter metals, alumn, scandium, etc) check with race car builders, especially those racing up Pikes Peak. Or find a bike frame builder - they are in the Springs, and certainly parts up North. Find some old free busted frames to practice on too!
