Add Performance to Twin Cam Harley-Davidson Engines with K&N

Sep 14, 2006

The Twin Cam Harley-Davidson engine was the first engine change for Harley in more than a decade. It boasts 88 cubic inches, dual cams, O-ring based gaskets. Twist the throttle and there is a difference, the bike passes instant power with a twist of the wrist.

K&N Engineering developed a RK-Series Air Filter Assembly (RK-3909-1) built around the legendary K&N High-Flow Air Filter. The latest addition is designed to get more horsepower and retain the stock appearance for 1999 to 2012 Twin Cam Harley-Davidson engines.

Custom Air Cleaner Assembly for Harley Davidson Motorcycles

"The custom assembly (RK-3909-1) keeps the factory appearance by using the stock air cleaner cover," said K&N Powersports Application Coordinator Lisa Watson. "There is superior filtration and performance with a K&N stamped laser-etched beauty ring."

The new RK- Series Assembly has a powder coated billet aluminum backplate that eliminates external breathers and features a built-in, dyno-tuned velocity stack. The result is a significant airflow increase to the engine without sacrificing filtration.

At this time the RK- Series Air Filter Assembly (RK-3909-1) does not fit Twin Cam Engines with the Magnetti-Morelli fuel injection system. "The Magnetti-Morelli systems have an oval port," said Watson. "This K&N kit fits a round port."

As with all K&N Motorcycle High-Flow Air Filters, the RK-Series Air Filters can be cleaned, re-used and is backed by the famous K&N Million Mile Limited Warranty.

U.S. Nationals Stock Eliminator Winner at O'Reilly Raceway Park uses K&N

Sep 13, 2006

It was a good day at the 52nd annual Mac Tools U.S. Nationals at O’Reilly Raceway Park at Indianapolis for NHRA Racer Dan Fletcher. With his 1969 Summit Racing Camaro Fletcher defeated David Edwards in Stock Eliminator.

Fletcher’s final round win in the $2.6 million NHRA POWERade Series was his fifth NHRA National Event win. “I drag race for a living, almost every weekend,” he said. “It’s been a good year.” The race is the 18th of 23 events in the NHRA POWERade Drag Racing Series.

Fletcher has raced full time since 1997 and spends weeks on the road. “I drive to the races from about the middle of February until the middle of November,” said the 40 times National Event winner. “The hardest part is being away from my family, but it’s better than having a day job.”

The Churchville, New York resident also uses K&N Engineering Air Filter and Oil Filters. “My cars performed flawlessly with K&N,” said Fletcher. “With K&N products my engines outlast and outperform other cars.”

The next stop on the NHRA POWERade circuit is the 22nd annual Toyo Tires NHRA Nationals at Maple Grove Raceway in Reading, Pennsylvania on September 15th through 17th.

Team Babbitt's Enxus Oil Kawasaki Readies for BooKoo Arenacross

Sep 12, 2006

Team Babbitt’s Enxus Oil Kawasaki is gearing up for another season of BooKoo Arenacross.

Josh Demuth BooKoo Arenacross Champ

In February, Josh Demuth won the BooKoo Championship Title in the 2006 BooKoo Arenacross Championship Series presented by K&N Engineering. Demuth withstood a full season of ups and downs to take home the 250, 450 and overall championship titles for Team Babbitt. The day after the final race, Demuth announced he was retiring from racing.

One month later, the 27-year-old came out of retirement and secured a deal with AMA supercross for the BooKoo Honda team.

“We’re sorry to see Josh go, but we’re happy for him,” said Team Babbitt’s Enxus Oil Kawasaki Manger Denny Bartz. “If Josh was coming back it would make things a lot easier, but our team has another shot at back to back championships.”

Team Babbitt uses K&N Engineering products during the competition. “We dyno tested K&N Air Filter (KA-2506XD), said Bartz. “The result was one horsepower gain. That is a huge amount in arenacross racing.”

Funny Car Racer Phil Burkart Readies for Toyo Tires Nationals

Sep 12, 2006

Racer Phil Burkart is preparing for the annual meeting of avid fans and machinery in the rural Pennsylvania countryside at Maple Grove Raceway.

As he readies for this weekend’s Toyo Tires Nationals, Burkart has recently put big round wins on the board at both Memphis and Indianapolis. He has vaulted himself back into the POWERade top ten for the first time since late May.

At Burkart’s opening round win at his most recent race, the Mac Tools U.S. Nationals in Indy, the Checker, Schuck’s Kragen Funny Car driver pulled off a major hole-shot win.

“Things have definitely been better for us over the last two races, and we’re building off that,” said Burkart. “Not only that, but our second round losses were both nothing to sneeze at either. We were beat by Eric Medlen and Robert Hight in those two rounds, and we have them both a battle to the end, so there’s nothing to be ashamed of there. We went through a period of not being able to get a win light, no matter what we did, and it feels good to get off that streak.”

Burkart and his crew use K&N Engineering’s Premium Performance Gold Oil Filters(HP-5001). “The thick canister walls on the K&N Filters have extra strength and durability,” he said. “It reduces the risk of damage from debris on the race track.”

Burkart is taking it one race at a time and one lap at a time. “We plan to win as many rounds as possible,” he said. “We aim to keep going.”

Offroaders with Honda's CRF450R Get Optimum Performance with K&N Air Filter

Sep 6, 2006

In the off-road world Honda's CRF450R was one of the most significant motorcycles introduced in 2002. The 450 engine is very fast and powerful and Honda put an excellent suspension system on the motocrosser with heavier springs and slightly different valving.

K&N Engineering has just released a Replacement Air Filter (HA-4502) that fits the 2002 Honda CRF450R. K&N's MX XStream Air Filter (HA-4502) is pleated and offers a substantial amount of surface area over the typical foam filter, providing longer service intervals and lots of fresh air to keep it breathing strong.

MX XStream-Top Replacement Air Filter for Honda CRF450R

This Replacement Air Filter (HA-4502) was designed with two pieces for easy installation and removal. It comes out of the box pre-oiled and with the top off. It is easy to install the base into the airbox and follow up with the installation of the top for a snug, precise fit in the bike.

K&N also provides a 1 oz. tube of grease to ensure a perfect seal at the top and bottom of the airbox. A machined aluminum spacer allows you to tighten the filter into place, keeping the filter sung without damaging the filter media.

The K&N (HA-4502) is built with an epoxy coated aluminum wire mesh, incorporated into a back-fire screen which protects the filter element, while delivering optimum air-flow.

All of K&N Off-Road Replacement Air Filters are washable and reusable and are covered by our K&N Racing and Off Road Limited Warranty. The 2002 Honda CRF 450 is a green sticker bike, the last of its kind. It is a much wanted choice for off-roaders who want to ride on public lands.
