A lot of weirdness, correctly ridiculous custom motorcycles have appeared lately. I found another one, and this one is so good I think it’s the best yet. The 1972 Honda Double 750 Salt Flat Racer “Anti-Christ” is a beast housing two Honda CB750 engines working together to set Bonneville speed records.

I’m a big fan of doubling vehicle engines. There’s something a little silly about adding power through the “more engine” solution, and the end result is often beautiful, especially on a motorcycle. For Boris “Bob” Guynes, this twin-engine custom motorcycle to come at auction embodied his love for Hondas and racing.

Guynes, who died late last year, lived what sounds like an incredible life. Mecum Remarks that the Army veteran has accumulated more than 60 years of racing and building motorcycles. He would try to set a speed record at Bonneville on one motorbike and then race the infamous Isle of Man TT on another.

His collection of bits of two-wheeler history rides Mecum thanks to his son, Lawrence. You will quickly notice that almost all motorcycles are Hondas. Like Lawrence Explain in Mecum, his father really liked some vintage Hondas:

“He loved Honda’s mechanical theory; he was always passionate about engineering and subscribed to the philosophy.

The piece de resistance of the Guynes collection is the 1972 Honda Double 750 Salt Flat Racer, nicknamed the Antichrist. According to Lawrence, his father dreamed up a build so extreme that even Honda itself wouldn’t create it.

The Antichrist starts with a pair of modified Honda CB750 engines. It was a good base for a machine as wild as this. As silodrome Remarks, the CB750’s advanced engineering has made it the benchmark for superbikes. It featured a transversely mounted inline-four with an overhead camshaft and rock-solid reliability. Many of them are still on the road today, which is a testament to their durability.

A single CB750 engine is good for 68 horsepower. This? It makes at least 136 HP before changes. Mecum explains some of the changes. Most importantly, the motors are linked together via their primary drives.

The monster is powered by two carburetors per engine, drawing air through stacks of velocity. Normally each engine would get air and fuel from a rack of four carbs.

Lubrication for the creation comes from a dry sump oil system with an external catch canister.

The exhaust is also quite impressive, as it goes from eight pipes to four.

It all sits on top of a custom-built frame that’s topped off with a fuel tank from a Honda 450 twin. And yes, it’s just as heavy as it looks at 1,000 pounds.

Stopping all that weight are giant vented four-shoe drums. Lawrence says this bike was meant to make a statement to Bonneville that his dad didn’t play.

I believe the message was successfully sent and received.

Guynes’ friend Ray Byrne was able to pilot the machine, but unfortunately Mecum doesn’t note how fast the thing actually is.

Mecum also warns that it is not road legal. However, with the addition of a brake light, turn signals, and mirrors, a number of states would issue a license plate to this thing.

Lawrence hopes whoever buys the Antichrist doesn’t try to race the unruly bike. But if he tickles your imagination, your encounter with the devil is at Mecum in Las Vegas on January 27. I would love to see it with license plates on a highway.
