Aluminum gas tank(leaked and inconsistant tune), dynamite fuel filter (un-tunable, lean one second rich another, newguy can back me up), anything hotbodies.

I have bought so many useless hopups that sucked and sucked my wallet dry that I can't even think of none. That's how many there was.

I calculated what I spent including my maxx in the first two years of owning it. I came up with $1500, and all I had that was decent was a motor and tires. After fully scoping out the UE stuff I know not to buy anything else except UE or "supermaxx approved" product.
