Formula Waaagh!

Waznex checked his fuel tank for the third time. He had been looking forward for this moment very much. He´d been dying to show Big Boss Gruntsnig that he was twice as fast as the bikers from the Hollow Bones warband. Waznex looked up from the fuel tank and made the thumbs up sign to his lads that he was ready. "Everyfing okay Boss!" he yelled. Gruntsnig nodded in reply.
On Waznex´ left was another biker; Morgug. He was said to be the fastest boy in the Hollow Bones. His bike was very impressive, with lots of chrome and red paint.
"But ´is bnike ain´ as good as mine." Waznex thought to himself.
Waznex bike didn´t have as much chrome, but it was very much redder.
"Bikeboyz, start yer engiens!!" a huge Nob roared.
Waznex kicked his bike into life. As he revved it up, he shouted to Morgug: "Don´ya know dat da red wunz go fasta!?" A huge blast from a shoota marked the start and Waznex and Morgug was off in a cloud of dust.

Morgug and Waznex raced almost head to head. They were also dangerously close to each other. Suddenly, Morgug changed into a gear that Waznex didn´t have. He roared past Waznex with ease and shouted: "Eat dust, Groxbait! Hurhurhur!!"

Morgug´s laughter disappeared in the roar of the engiens. Waznex gritted his teeth over this. He would show Morgug why his clan was called Da Twisted Nex and why they´d choosen that particular name. But then he remembered what the Mekboy back in the pits had said: "If ya get inta trouble, jus´ press dis button."
Waznex took his eyes off the road and looked down on the controlpanel of his bike. Between the speed-o-meter (a Mekboy invention) and the fuel gauge (another Mekboy invention) was a little red button.
"Red makes bikes go fasta!" Waznex thought and pressed the button.
What Waznex had taken for an extra fuel tank sprung into life and he accelerated dangerously fast as the second motor kicked in. The power given from the motor was enormous. So enormous Waznex almost lost control of his bike. Waznex felt joy flowing throughout him as he felt the wind whip his face.
"´Ere I go! ´Ere I go! ´Ere I go!" he started chanting.

As he closed with Morgug´s bike, he pulled out his slugga. Morgug was going to be less that Groxbait when Waznex was done with him.
"You´re gonna end up wiv a flat ´ead an´ a flat tyre, Morgug." Waznex thought to himself as he got within firing range of his slugga. As the gun kicked in his hand, Waznex smiled maliciously.
