Thanks everyone. Dave this bike was years ahead of it's time. It incorporates two counter rotating crankshafts similar to what Yamaha is using today in their Moto GP bikes. It is a 1,000cc's with 250 cc's in each cylinder. The cylinders fire 1234 instead of 2 and 2 like one would assume. This makes them sound like no other bike on the road. It has a quick detatch rear wheel. Pull one axle and the wheel slides out leaving the rear sprocket, chain and brake drum attached to the bike. Also uses a Plunger type rear suspension. The style is actually a bobber from the era. Highly modified from stock by the owners father. The engine was originaly built by AJ Lewis in Los Angeles and it set a record at Bonneville. Since then it has seen some pretty rough treatment including throwing a rod through the cases. Had to be completly rebuilt.
