K&N YA-1515 Washable Air Filter Increases Airflow in the Yamaha T150

The YA-1515 product side view for the Yamaha T150

The YA-1515 is designed for excellent filtration and added airflow

Yamaha’s “underbone” frame-style T150 motorcycles are big sellers world-wide for good reason. The Yamaha T150 is badged in various markets as the Exciter, Sniper, King, Jupiter, or more subtly as the Y15 ZR. The little bikes are nimble, rider friendly, and affordable. In short, they are a fantastic mix of scooter and motorcycle.

Anytime you are dealing with a limited displacement motor like the 149.7 cc single in the Yamaha, a boost in performance is a welcome thing. That is the design goal of the K&N YA-1515.

The YA-1515 features K&N’s free-flowing cotton gauze filter media that increases airflow to the engine. That boost in intake volume often results in crisper throttle response and quicker acceleration.

The same pleated, oiled, cotton gauze filter material that provides ample airflow, also filters that air very efficiently. K&N’s in-house filter testing resulted in an impressive estimated overall filtration efficiency of over 98% with the YA-1515.

That estimated efficiency will keep the Yamaha T150 running clean and safe. You can access all of the test protocols and results by clicking on the "Air Filter Test Data" link on the product details page.

A couple of the most appealing features of the Yamaha T150 are the bike’s low-maintenance requirements and environmental friendliness. The washable and reusable nature of the YA-1515 enhances these traits even more.

Cleaning is made simple with the K&N 99-5000 filter recharge kit, and K&N’s Million-Mile Limited Warranty means you will not need to buy another filter for the life of your Yamaha.

When you combine the YA-1515’s excellent filtration, reusability, and the possibility for a bit more power, it emerges as the clear air filtration choice for your Yamaha T150. Check the application list below, and consult K&N’s easy-to-navigate online application tool.

Mechanical Issues and Race Contact Keep Greg Adler Off Podium in LOORRS Opener

Adler battled to the third position in both races in Chandler, Arizona before having truck issues

K&N-sponsored Greg Adler and Team 4 Wheel Parts began their assault on the 2017 short course off-road racing season in Arizona’s Valley of the Sun. The season got off to a hot start…literally. The temperatures at Wild Horse Pass Motorsports Park, in Chandler, Arizona, were unseasonably hot with temperatures flirting with triple digits for the Lucas Oil Off Road Racing Series (LOORRS) season kick off.

The series' marquee Pro4 division drivers took little time in demonstrating just how anxious they were to get back to racing and to put on a spectacular show for the fans in attendance. That first-race adrenaline manifested itself in an abundance of aggressive driving. The first three laps of the race were littered with caution flags and extreme contact. Doing his best to stay free of the carnage, Adler methodically worked his way through the field.

"After a few days here at the track setting up, testing, and then qualifying for the race, these guys were ready to go today," said Adler. "It took us the first three laps just to get a clean start, but when we did, it developed into a great race. There was plenty of beating and banging but that's what Pro4 racing is. This is not a sport for the timid."

While trying to steer clear of some of the unreasonably aggressive driving at Wild Horse, Adler continued his pursuit of the leaders as he battled towards podium contention. With ten laps to go in the 18-lap main event, he made his move with a strong pass to capture into the third spot. Unfortunately, as Alder battled to maintain the position, there was a mechanical failure that abruptly halted his advance and ended his day.

"We were on a good run and had the speed to finish strong today. Things move quickly out there. We raced hard, made some passes, and moved through the field to put ourselves in a great spot. Then in a moment, the truck has an issue and your race is done."

After a late night, Crew Chief Mike Seat and the 4 Wheel Parts team had the 900-HP Pro4 ready for the second race of the weekend's doubleheader. A solid qualifying effort secured a second row start for Adler. When the flag dropped, a fantastic start resulted in Adler moving into the third spot. With a tightly packed field jostling for position, Adler’s #10 truck made contact with another racer. The contact damaged Adler’s front tire, which would present a serious dilemma just laps later.

Just after the mid-point in the race, Adler was solidly planted in third but was facing a difficult choice. He could opt for a tire change or he could stay on the course and risk potentially catastrophic damage to his truck. Adler elected to pull off the track and into the pits.

Even with a quick return to the track, Adler found himself a lap down to the leaders, a gap that would prove insurmountable. While he finished the event, the result was not indicative of the on-track effort and pace he maintained throughout the day.

"It's disappointing," said Adler. "The guys were up late to give me a great truck and we came out battling for a podium. Today was a much different race. For the most part, everyone kept it clean and there weren't a lot of opportunities for us to get caught up with the field. What we do know is that this team has a strong chin and can take a punch. We stayed on our feet to make sure we brought it home to the finish today. Now we're going to be coming out swinging in Ensenada."

Certainly Adler and Team 4 Wheel Parts will be chomping at the bit for the return to Chandler which is scheduled as the site for the season finale. However, there is a lot of racing in various venues before that return will come to fruition.

Ricky Stenhouse Jr Picks Up First Career Win in the Geico 500 at Talladega Speedway

Ricky Stenhouse Jr celebrating his win at the Geico 400

Ricky Stenhouse Jr. won his first Monster Energy NASCAR Cup Series race of his career, coming in his 158th race and did so in serious fashion. In the Geico 500 at Talladega Speedway, Stenhouse Jr. passed Jamie McMurray on the final lap, beating McMurray by 0.95 of a second, propelling him to reach the checkered flag for the first time.

"This is for all the guys at the shop--we’ve been terrible for a long time," Stenhouse said. "This year, every race, we’re just getting better and better. We knew Talladega was a good race track for us. It’s been a good one in the past.”

The win was an uphill climb for Stenhouse, as he led for the first 13 laps of the race, and did not lead again until the penultimate lap. Stenhouse received 49 points and 5 playoff points. He currently sits in 12th place in the Monster Energy NASCAR Cup Series standings.

“It feels really good to get that first win here” Stenhouse said. “I remember sitting in the bus watching this race and knowing that this is a racetrack that we've had good success at, we've ran well. You know, so close to home. It feels awesome to get the first win here.”

Jamie McMurray finished in second place, 0.95 seconds away from finishing in first, and getting his first win of the season. McMurray was passed by Stenhouse Jr. on the final lap, after passing Kyle Busch in the process.

“Like there's times when you feel like you're going to have a good run and you don't, and then there's other times that it happens,” McMurray said. "So it was a good overall day for us.”

Kyle Busch finished in third place, who led three times for 48 laps. Busch led for a race high 39 straight laps before being passed.

“Overall we had a great car,” Busch said. “We were up front the beginning part of the race, kind of fell back, like McMurray said, through the middle stage of the race, and then got back up there at the end. We were in the dog seat and the position to win, we just had to hold him off, and we didn't do it.”

A crash on lap 169 wrecked 18 of the 38 cars in the race. Chase Elliott tapped the back of AJ Allmendinger’s car, and flipped onto the hood of Joey Logano’s car. The stoppage took 26 minutes to clean up, Busch restarted in first place.

Dale Earnhardt Jr. finished in 22nd place in his last spring race of his career.

Kyle Larson continues to be in first place in the Monster Energy NASCAR Cup Series Standings with 428 points and 7 playoff points. Martin Truex Jr. is in second place with 374 points and 10 playoff points. Brad Keselowski is in third place with 367 points and 11 playoff points.

The next race in the Monster Energy NASCAR Cup Series will be at the Go Bowling 400 at Kansas Speedway.

K&N-Sponsored Superbike Racer Kyle Wyman Rides to Top 5 Finish at Road Atlanta

Kyle Wyman catches air on his way to a top-5 finish at Road Atlanta

Kyle Wyman rode his Excelsus Solutions/KWR Superbike to a top 5 finish Sunday at Road Atlanta in the second round of the MotoAmerica Superbike series. The K&N-sponsored road racer put up a career ride in the Sunday race in Atlanta, Georgia.

Wyman started the weekend impressively by posting the 5th fastest time overall in the qualifying practice sessions. He was less than a tenth off of the factory teams, which is an indication of the blazing one-lap speed of the non-factory rider.

"Friday was a bit of a bumpy start with some mechanical gremlins, but we were still able to put in a time," Wyman said. "Friday's sessions are important because it determines the top 12 riders who will move on to Superpole Saturday morning. Being fifth overall and the top rider after the factory teams is our goal and we were able to accomplish that."

With that goal realized, Wyman moved on to the next phase of his Road Atlanta plan. Wyman had only a 30-minute session Saturday morning before Superpole to dial in a race-setup for the bike which is crucial for the 21-lap races scheduled for Saturday and Sunday. Wyman was able to qualify in 8th position in Superpole, which he viewed as a disappointment after his Superpole performance at the Circuit of the Americas (COTA) in round one.

KWR Racing worked out setup issues for a strong race two

"We tried some things in the morning practice to see if we could make the bike better over a full race distance," Wyman said. "In Superpole my goal was to get back on the second row of the grid again like we did at COTA. I made a mistake in my first sector of the “Q” (qualifying) tire lap and it cost me some time. We would have to settle for the third row of the grid."

In race one on Saturday, Wyman felt that he and the KWR team shot themselves in the foot with a failed setup decision. That experiment gave Wyman fits in the 21 lap race, especially with the bike's rear end.

"In race one I got off to a bad start and it got worse from there," Wyman said. "From the get-go I felt unsure of the rear end. We tried a different setup for the race compared to qualifying and the bike was just really hard to ride from the first lap. We still were able to hold on to a respectable finish."

While the 9th overall and the 6th in the Superbike class in race one was respectable, Wyman clearly wanted more from the Sunday race. The KWR team went back to the drawing board to come up with setup changes for race two. Those changes proved to be just what Wyman needed to post an incredibly impressive 5th overall on Sunday.

"(In) race two, I actually got off to a horrible start again, but was able to make quick work of some guys and make good passes," Wyman said. "After I cleared the Superstock guys I was pleasantly surprised to see my pit board climbing up and the gap growing like crazy behind me. For a long time I was just a second or two off the lead group and could see all the shuffling that was happening up front."

Wyman built up a 17-second gap over the 6th place rider by the finish, and chalked up his best ride of 2017.

Setup success and race result progress is the key to the early season rounds, and that’s exactly what KWR Racing experienced over the course of the Road Atlanta race weekend.

"Overall I'm super happy with the result because we made such huge progress over race one, and eclipsed my Superpole time twice during the race,” said Wyman. “My crew has been working so hard to give me a solid bike and they have done a great job. I can't wait to continue at Virginia in a couple weeks where I know we will be strong."

If you own a Yamaha R1 and are looking for the same filters that Kyle trusts on his bike, look no further than K&N. For the 2015-2017 Yamaha R1, K&N makes the YA-1015. And if you track your bike and want a little more airflow, you should check out the YA-1015R.

K&N-Sponsored Formula Drift Driver Vaughn Gittin Jr. Finishes 4th at Orlando Speedworld

The trio of K&N-sponsored Formula Drift drivers entered Formula Drift's second round of the 2017 season, with Matt Coffman, Chelsea Denofa, and Vaughn Gittin Jr. all looking to build on their performances from Round 1 in Long Beach, California. Orlando Speedworld marked the first banked oval of the season, and the abrasive 3/8-mile asphalt track caused some challenges for the teams who needed to find a balance between pushing 800+ horsepower to the ground and making a set of tires last at least two full laps, a requirement of the Formula Drift regulations.

Friday’s qualifying session had a mixed bag of results for the K&N drivers. Coming off of a Top 8 finish in Long Beach and a class win at the Oregon Trail Rally, Matt Coffman was the top qualifying K&N driver in the 9th qualifying position. Chelsea Denofa out-qualified his Ford Mustang RTR teammate Vaughn Gittin Jr. in 13th place, while Gittin Jr. had some trouble with his Mustang holding too much grip in the Nitto tires and would end up with a 22nd place qualifying position. All three drivers felt more comfortable going into Saturday’s tandem battles knowing that several other drivers struggled with the conditions on Friday, and any driver on the grid was capable of bringing home results in the tandem battles.

Saturday brought a new day, and a refreshed outlook for the K&N drivers. In practice, all three drivers were feeling much more comfortable in their cars. Unfortunately, Matt Coffman had a run-in with the wall late in the morning tandem practice, and was unable to fix his car before his scheduled tandem battle with Piotr Wiecek. Although the weekend results were lower than the team had hoped for, Coffman currently sits in 11th place overall after two of eight events. Coffman is confident he can return strong results at the next round in Atlanta.

Chelsea Denofa was paired with Jhonnattan Castro in his tandem battle. Denofa had a good lead run, but would miscalculate the transition on his chase run and collide with Castro on the infield. Denofa’s exit in the Top 32 round was his second of the season, and he currently sits in 22nd place overall. Denofa is feeling more comfortable in the Ford Mustang RTR as he continues to get more seat time, and is still building familiarity with the rest of the Mustang RTR drift team. Denofa is confident that his results will turn around soon as he looks ahead to the next round at Road Atlanta, a favorite track for Denofa.

Vaughn Gittin Jr. would face fellow Ford Mustang driver Justin Pawlak in the Top 32 round and the two have developed a bit of a rivalry over the years. Similar to Denofa, Pawlak would misjudge his transition when chasing Gittin Jr. and collide with him. Pawlak was deemed to be at fault, and Gittin Jr. moved on to the Top 16 round. In the top 16, Gittin Jr. would face Kyle Mohan and his Mazda MX-5, but a spin from Mohan in the chase would give Gittin Jr. the round win and move Gittin Jr. into the Top 8.

Fredric Aasbo narrowly edged out Vaughn Gittin Jr in the Final 4

Up next, Gittin Jr. would face Ryan Tuerck in what would be one of the best battles of the day. After a first set of battles wasn’t enough to decide a winner, Tuerck would face a mechanical issue in his chase run and shut the car down early, which gave Gittin Jr. the pass into the Final 4. Facing Fredric Aasbo, Gittin Jr’s day would end as Aasbo’s car was much faster in drift, and Aasbo would go on to win the event. For Gittin Jr., the turnaround from 22nd qualifier to 4th place finisher was a welcome one, but Gittin Jr. still felt he had the car that could have won the event. Gittin Jr. currently sits in 5th place overall, just 55 points away from Aasbo in the overall championship chase. Gittin Jr. is the defending Atlanta winner, and has podiumed at the track a total of four previous times.
