The Beattie Files: Call me Lucky

Young Mr Beattie recalls an encounter with a big character with an even bigger motorcycle

(Ed's note: These are excerpts from young Beattie's book on some of the more colourful incidents in an action-packed life. See the end of the piece for more info.)


February 2025

As we wheeled the monstrosity out into the carpark at the Sydney Motor Cycle Show circa 1986, a growing procession of bike enthusiasts followed. While show exhibitors displayed some of the world’s latest and most exotic motorcycles inside, hundreds of visitors ignored them as they congregated around our small group outside the exhibition building.

 

There was certainly nothing pretty about the bike that was drawing all the attention. In fact, to be honest, at the time it was pretty ugly; a conglomeration of unpainted frame tubes, make-do wiring and home-grown engineering. But to hardcore bikers, it was unquestionably the star of the show.

 

A lot of its appeal had to do with the massive lump of metal that dominated centre stage between the wheels. To anyone with petrol running through their veins, it was a mechanical work of art, and an amazing engineering achievement.

 

When the Douglas DC3 aircraft starter motor spun the engine into life, even more show visitors thronged out into the carpark to see what all the commotion was about.

Five litres of angry V-twin engine exploded into flame-belching life as each cylinder spat its exhaust out through stubby pipes that did nothing whatsoever to muffle the combustion process.

 

The creator of this monster, Dubbo’s Lucky Keizer basked in the glory of it all as his mechanical Frankenstein spewed fire – anyone who was within range and who wasn’t singed by the flames ran the risk of being deafened by the racket.

 

Lucky let the engine run for a couple of minutes and just to demonstrate how well balanced – as opposed to its creator – it was, he would plonk an empty beer can on top of the air filter. It didn’t even rattle, the engine’s primary balance was so good.

 

For the remainder of the show – and much to the annoyance of show organisers and exhibitors – we repeated the ritual several times, drawing large numbers of show visitors each time.

 

I was Editor of Australian Motor Cycle News at the time. One of our Sydney freelancers had heard that some guy out west was building a “mad mega-bike” in his barn, which was how Lucky and his mighty Merlin found their way on to the magazine’s stand at the show.

 

Lucky explained that he’d come up with the concept after purchasing an original 27-litre Rolls Royce Merlin engine off a farmer in outback NSW. The engine, as used in WWII fighters and bombers, had lain dormant in a paddock for years and 

bore the scars of decades spent at the mercy of drought, floods and fires.

 

“It was really buggered, eh,” said the former speedway rider. “One end of it had actually more or less corroded away, but I offered him a couple of bucks for it and he seemed glad to get rid of it.

“As soon as I saw it, I knew what I wanted to do. I made up this bloody big industrial hacksaw and got through a couple of cartons of piss over two days as I sawed out the middle two cylinders, which were actually in quite good nick.

 

“I cut through everything from the heads down through the block and the crankshaft. Then I had to think how I was going to get the bloody thing to actually run."

 

For practical purposes, Lucky ended up machining up his own crankshaft and camshaft drives, but retained most of the other major structures and components, ending up with a 5000cc V-twin engine.

 

Other driveline components were, in classic Aussie outback tradition, borrowed from the Kingswood. Literally. Linking the engine to the wide 15-inch car rear wheel and tyre was a three-speed Holden gearbox and clutch.

 

By the time of its show debut, the bike was still in pretty basic form, and certainly not anywhere near street-legal. But a couple of years later, Lucky had taken it to a whole new level. By now it was much more street-worthy, with actual working brakes and suspension, but typically he’d gone a little overboard in other areas.

 

Instead of the original four-barrel carburettor – again borrowed off an old Holden he had lying around – Lucky had installed a supercharger between the two massive cylinders. But just to be on the unsafe side, he’d also hooked up a nitrous-oxide injection system, which could add another 100 or so horsepower to the already stupendous 450hp produced by the giant twin.

“I’ve had a couple of wild experiences with it,” confessed Lucky. “The first time I used the nitrous, it blew the carby right off the motor. It turned out the nitrous spun the crank up so fast the cam-drive belts spun a couple of teeth and the motor back-fired. Think I’m gonna have to put a bit more work into it...”

 

Word soon spread of the motorcycle monster from Down Under and it wasn’t long before Lucky was accepting offers from major bike show promotors in the US and Europe to display his crazy creation. Lucky and the Merlin starred at Sturgis and Daytona, where he also ran the beast at a bike-pull. Run along similar lines to a tractor-pull, riders compete to see how far they can tow a weighted sled. In Lucky’s case, he reckoned the locals were a bit miffed at the unfair competition.

 

“They whinged because I pulled the sled further than anyone else on the night, so they just banned me from running, the sooks! It didn’t help that I was pulling the sled around like it was a trailer,” he chuckled.

 

Of course, the big question is always how fast will it go and Lucky admitted to exceeding open road limits by a considerable margin on one memorable run.

“I reckon I got 200mph (320km/h) out of it once, but it was a bit freaky as I didn’t have a fairing on it so my eyes were watering and I wasn’t seeing too good,” he recalled. “Actually, I didn’t know exactly how fast I was going at the time as I didn’t have a speedo on it, but I worked it out later from the revs and gearing. I decided that was enough because the front tyre was in pieces by the end of it. I definitely lived up to my nickname that day I reckon …”

 

Eventually the big rig drew international attention and the last I heard it was now in the hands of a private American motorcycle collector. Lucky also embarked on building and running a land speed record streamliner bike with a 351 Ford V8 engine for power, but from what I understand it never made it into the record books. Instead, it can now be viewed (minus engine) at the popular motorcycle haunt known as the Moo Moo Roadhouse, in Mooball on the Tweed Coast in northern NSW.

 

Haven’t heard from him in a long time, but I assume he’s now feeding his need for speed with another mad machine somewhere in the Outback.
