G2 Squared Dyna Wide Glide
“I have a passion for big motors with a lot of power — like blown, alcohol speed boats,” said Andrew.
ANDREW: I got this Dyna Wide Glide as a stolen retrieval bike from an insurance company. It had no handlebars, no exhaust pipes or anything. The G Squared motor is its most outstanding feature. It’s naturally aspirated, big bore, big cube, and big horsepower. It’s the motor you would normally find in a drag bike.
The G Squared engine can only be ordered in parts; you can’t get one assembled. So to fit it together required lots of machining which meant the need for a full machine shop like APL Performance Bikes — not just a regular bike shop — because it meant clearance rods, cams, pumps, cases, barrels, a unique pump — it’s got a high-volume scavenging and oil pump system in it. Everything is built similar in design to an Evo or Twin Cam but twice as strong and twice as big.
ADAM: We ran into an issue with how to drive it from such big horsepower to the gearbox because nobody in America makes parts for Dynas. So we went to Newby Engineering. Wayne Newby is a top number one, three-time Australian champ. He designed and wrote a CAD program for a BDL 2000 to fit on a Dyna. Belt Drive Limited (BDL) in America wouldn’t do it so we just had to do it ourselves. We had to accommodate the power and keep the integrity between the motor and the gearbox, strength and support plates. It was a major project.
ANDREW: When you put that size engine into a Dyna — because of the rubber mounting and the swing-arm setup — the gearbox has a tendency to swing around and snap off from the primary, so we had to accommodate the power of the motor and make sure we had no failures.
It also has drag race characteristics—it has a breather that breathes crankcase pressure straight out.
ADAM: It’s got a S&S D-Series carburettor and you would probably swear that it was fuel injected if you rode it because the carb is the right size for the motor. People commonly make the mistake of sticking a D carburettor on a 100-inch motor or something smaller; the D carburettor is for drag race motors. When you ride it, you just tap it and it’s nice and smooth and fast.
The barrels go deep into the cases which gives it integrity. It’s got huge pistons; that’s how you get up to the 126 cubic inches. It’s four and three quarters across the width.
ANDREW: A guy by the name of Dan Murdoch was, in his day, a pioneer in flame work. Unfortunately, he got sick with cancer, sold up shop and died. It’s special having his paint on this bike because that’s the right era. It’s a 1994 model, Harley-Davidson Dyna Wide Glide and the eagle, the silver, all correspond with that era.
The foot pegs are a bit unusual with the skull heads on them; got them on one of my many trips to the States. I used to have a foot-stand too with the femur of the leg standing out, but it used to get in my a friggin’ road, man.
It’s got twin Performance Machine calipers on the front-end, ProOne floating discs, and that front steering brace which was also done by Wayne Newby.
ADAM: It probably hasn’t got the ideal rake for a drag bike, definitely not, but it’s a compromise for something that looks good.
So… for drag racing, it’s a Pro Street but they’re letting it in the 124 Class with added weight. We’re sticking with the 180 rear wheel because we don’t need any big, fat 250 tyres sliding around down the quarter. We want to run it down the quarter, have fun on a Wednesday night, whilst still sufficing the need for something else after the boat racing.
