1992 Banshee Rebuild

1970713_Monster_mainEthan Grant is a self-proclaimed gearhead. He says while other kids were playing sports and going to dances, he and his buddies were wrenching on things. You see, he felt more at home building and tearing apart go-karts and mini-bikes than he did trying to catch a ball or hold hands with a girl. He caught the powersports bug early and could never shake it from his system. To this day, he’s hooked on engines, power and his 16-year-old Yamaha Banshee.

“I put so much work into my ’92 Banshee over the last year and almost $8,000,” explains Grant. “Riding is one of my main passions in life so I decided to completely customize it to my liking.”

Grant says he’s been relying on Trinity Racing to supply him with lots of parts. However, with his ’Shee, he wanted more than bolt-on mods. He desired a complete rebuild. That involved tearing down the quad to the naked chassis.

1970713_GrantStarting from there, he powder coated the frame and then focused on the powerplant. The Banshee’s trademark twin-cylinder two-stroke was in need of a boost and Trinity supplied the fix. That came in the form of a Stage IV system, single Keihin constant velocity carburetor and jet kit and high-performance reeds. A Stage IV header and twin silencers improved the horsepower and gave the Banshee a devilish note. The quad’s breathing was improved with a K&N air filter, prefilter and by removing the airbox.
The engine not only functions, but looks sexy, too. “[I added] New billet covers on both sides of the engine,” Grant says. “One is a clear cover so you can see the clutch spinning when it runs.”

1970713_Monster_FrontIn terms of bolt-on mods for the chassis, this Banshee is wider and longer and has the length and width to match its improved power. “I put a new extended plus 4-inch swingarm and extended the axle 2 inches and also added front plus 2-inch A-arms,” explains Grant.

To improve the Yamaha’s night vision, Grant added some polished billet aluminum Lazer Star headlights and a billet LED red taillight.

When building a Banshee, we’ve learned over the years the quad’s appearance is as important as its performance. Grant purchased Fullbore Innovations Plastic and a billet aluminum grill which was chromed. An RIS Designs 3-bar Banshee bumper improved this quad’s front end appeal.
Grant says he loves the AC Racing Pro Pegs. He’s particularly fond of the black powder coat finish and contrasting chrome pegs.

He added Works performance shocks up front and a rear boinger from Shock Therapy that was reworked by TCS. Even the new tire-and-wheel package (ITP Baja wheels with Holeshot tires) give the Banshee better traction.

Grant says, in September, he put his Yamaha on display in the Trinity Booth at the Sand Sports Super Show and it was the “center of attention.”
