It’s Monster Theater As The Monster Energy/Graves/Yamaha Team Debuts Its Newest Video

Thursday, September 20th, 2012


Cypress, CA September 20, 2012 – Round 10 of the GEICO Motorcycle AMA Pro Road Racing series was a big one for the Monster Energy/Graves/Yamaha team at New Jersey Motorsports Park. Two-time defending AMA Pro National Guard SuperBike Champion Josh Hayes “batted a thousand” once again on his #1 Yamaha YZF-R1 SuperBike as he earned his 9th pole position in a row, his 12th and 13th race wins on the season, and his 9th and 10th consecutive SuperBike victories this year, not to mention leading every lap from start to finish in both New Jersey races.

Meanwhile, Josh Herrin, rider of the #2 R1, battled back from the adversity of a practice-session crash early in the weekend to finish fifth in Saturday’s Race One and a strong second in Sunday’s Race Two.

For an up-close look at the two Joshes in action from NJMP, check out this video:

Also, in the video, you’ll get to meet Jim Roach, who is Josh Hayes’ crewchief. Jim talks about the Dunlop tires that have played a major part in Yamaha’s racing success all the way back to the days of Kenny Roberts and his Dunlop-shod Yamaha YZR500 GP machines.

Look for more videos to come from both of the Yamaha U.S. Road Racing Teams: Yamaha Extended Service/Graves/Yamaha and Monster Energy/Graves/Yamaha.

Dynojet Secondary Fuel Modules available from Graves Motorsports

Thursday, September 2nd, 2010
Dynojet Secondary Fuel Module

Power Commander Secondary Fuel Module

Most of today’s high performance, four cylinder Sport Bikes have two injectors per cylinder. The Power Commander V connects to 4 of those 8 injectors. In virtually all cases the PCV’s +250% / -100% fuel adjustability allows more than enough adjustment for all but the most radically altered engines. However, we recognize that there are people building heavily modified engines (extreme big bore, turbo, etc) that may require the adjustment of all 8 injectors.

Enter the Power Commander V Secondary Fuel Module. The S.F.M. connects to the upper injector rail using OEM connectors. From there, it is only a single cable connection to the PCV. Once connected, you will be able to adjust both upper and lower injectors by as much as +250/-100%

If the gear position input is connected on your PCV you will have the ability to adjust all of the injectors on a “per gear” basis (a complete map for every gear) as well as the ability to map each injector separately. That gives you up to 48 complete maps!

There will also be a “basic” mode that allows you to have a single fuel table that simply puts the requested fuel change in both upper and lower injector modules at the same time. For those of you that have modified engines that require more fuel than 4 injectors can provide, but do not need the complexity of mapping each cylinder and each gear separately, this setting is for you.

In addition to the increased fuel adjustability the SFM provides, it also allows for the use of the Dynojet Quick Shifter sensor on 8 injector bikes. On earlier Power Commanders an Ignition Module or Stand Alone Ignition Quick Shifter was necessary to use the DQS on bikes with 8 injectors. Now, you can have both added fuel control and shifter functionality at a very low price.

Graves Motorsports Prepares Bostrom Superbike Yamaha R1 For Jay Leno

Graves Prepped Yamaha R1

Cypress California, July 21, 2010 – The stars of the MotoGP World Championship made their way to California this week. They’re headed for Laguna Seca, of course, but on Tuesday you could not have been blamed for thinking the race would be held in Burbank.

The suburb north of LA is normally home to a lot of television and film production and star sightings are commonplace, but on Tuesday it was teeming with motorcycle racers… Fiat Yamaha’s championship leader Jorge Lorenzo, Monster Tech 3 Yamaha riders Ben Spies and Colin Edwards; Yamaha legends Kenny Roberts Sr., Eddie Lawson, and Wayne Rainey – even AMA Superbike championship leader Josh Hayes and Ben Bostrom were all spotted in the nondescript warehouse district near Burbank’s Bob Hope Airport – not a typical transfer point on the way to Laguna Seca.

But avid motorcyclists know that Burbank is also the location of Jay Leno’s famous ‘Big Dog Garage.’ Leno, host of the Tonight Show, is a member of the AMA Hall of Fame. His garage (actually a 70,000 sq. ft. complex with several full time employees) houses over 200 motorcycles and cars – ranging from pioneer motorcycles like his 1918 Pope to an 800-horsepower ‘Ecojet’ car tuned to run on recycled cooking oil. It’s definitely a garage and not just a collection, since virtually every vehicle is licensed and insured; Jay rides and drives all of them.

The latest addition to Jay’s fleet is fast and exotic, even by his standards – an ex-Eric Bostrom AMA Superbike.

“Last Fall, Jay auctioned off a custom Star V-Max to benefit Bailey’s Cafe, a charity that we both support,” said Bob Starr. “We were thrilled with the results of that auction; it benefitted a very worthy cause. But we realized that when he sold his V-Max, it left him without a Yamaha in the garage.”

“We wanted to make sure that Jay had a unique bike, that reflects his uniquely effective role as an ambassador for our sport,” Starr continued. “This R1 Superbike is not something that can be purchased at any price. It is virtually as-ridden by Eric. We put it into storage at the end of the 2008 season. We just asked Chuck Graves of Graves Motorsports to go through it and make sure it was ready to ride again.” The bike was a surprise gift for Leno, who thought he’d only agreed to host a dinner for Yamaha’s MotoGP riders.

It was hard to tell who was more star-struck. Jay and his garage staff met a ‘who’s who’ of Yamaha racing history. But even legends like Eddie Lawson do a double-take when they see the scope of Jay’s garage and workshop. “There are so many vehicles in here,” said Lawson, “that are just works of art.”

Since all his bikes get ridden, it will be up to garage manager Bernard Juchli to find a place to hang a license plate on this factory superbike. When we asked Bernard how he’d manage to register it, he smiled and replied, “I can’t reveal that.”

The job of going through the ultra-trick R1 fell to Team Yamaha’s Chuck Graves. Graves made a few concessions to making the bike ‘streetable’; swapping the Magneti Marelli ECU for a YEC unit, and the race dash for one with a speedometer. But the engine internals, fork, swingarm and more are pure factory unobtanium. “This bike was built before we homologated parts,” said Graves, “so really, a lot of these components just aren’t for sale, at any price.”

In all, over 100 of Yamaha’s ‘friends and family,’ and representatives from Dorna and Mazda Raceway Laguna Seca, attended the event, which included a great meal prepared by none other than Yamaha-USA’s own racing boss Keith McCarty. Tim Collins of Alpinestars presented Jay with a custom set of leathers to match the bike, and Troy Lee added a fantastic custom-painted Arai helmet, which included signatures and elements from the designs used by the legends and MotoGP riders at the dinner.

When he posed for photos with Lorenzo, Spies, and Edwards he quipped, “Yeah, this is great – I love being the slowest guy in the room.”

After dinner, as the event wound down, the riders prepared to travel up the coast to Laguna Seca and Jay – who works
