Rizla Suzuki's Chris 'Stalker' Walker took his best qualifying position of the season securing second place on the grid at the 12th round of the Bennetts British Superbike Championship at Donington Park today.
Stalker spent three practice sessions building up his effort, slashing his lap times every outing on circuit. He started strong in qualification but left his best effort to the final minutes, setting a blistering pace at the 2.5-mile long twisting and challenging circuit.
Cal Crutchlow was vying for the top spot on the time-sheets during every session and was challenging again in qualification but was held up by traffic on his quick laps, eventually ending up fifth fastest and heading up the second row.
In previous stories I talked about carburetors Rich conditions and Lean Conditions, this is all fine of course if you know how to detect if your engine carburetor is set Rich or Lean.
To help with that, I will explain simple means to detect the setting of your bike. With a perfectly tuned engine you will get the power you need, it amazes me sometimes what people spent on kits to improve performance, while all they needed to do is get the settings right.
Okay that said what is a Rich Condition, while a black, scooty spark plug is a sure sign of richness, there are other indicators that are a bit subtler and better ways of dialing in the carburetor jetting.
If your engine responds crispy at low throttle when it is cold, chances are the main jet is one size larger than it needs to be. Assuming, of course, that the idle circuit is correctly tuned.
Poor fuel mileage is another sign of richness and because of the way most of us ride our motorcycles, that richness is unusually the result of a needle that is too small.
Valentino Rossi sealed his tenth front-row start of the season ahead of tomorrow's Japanese Grand Prix at Motegi today, the Italian taking second place on an all-Michelin front row in between Dani Pedrosa and Nicky Hayden. Colin Edwards also had a good session, qualifying seventh at the head of the third row.
After making a poor start to the weekend by finishing 14th yesterday, Rossi made a step up this morning and put in the second fastest time in free practice. His qualifying session did not get off to plan however as he made an off-track excursion in the opening minutes and then found himself down in 18th place mid-way through. Edwards meanwhile, was doing little better in 17th, but both began to steadily improve as they worked on refining their race settings and finalizing their tyre choices for tomorrow
Once it came down to qualifying tyres it was clear that Rossi especially was on top form and his first run put him in second place, before improving again with his second tyre and moving one place higher
Kawasaki's Randy de Puniet and Anthony West overcame soaring temperatures and exhausting humidity at the Motegi circuit this afternoon, to qualify their Ninja ZX-RR machines on the second row of the grid for tomorrow's 24-lap Japanese Grand Prix.
Kawasaki wild card rider, Akira Yanagawa, will be chasing his team mates from the seventh row of the grid, after qualifying in 19th position today.
De Puniet opened proceedings this afternoon by switching to a qualifying tyre just before the halfway point in the session, capturing pole position with his first attack lap. The 26-year-old Frenchman held onto the top spot until the final six minutes, before finally being deposed by eventual pole sitter, Dani Pedrosa.
At 21, Casey Stoner sits at the top of his chosen sport, one race away from being crowned champion of the motorcycling world with the customary shower of champagne. Casey Stoner, met his wife Adriana Tuchyna, 18 at Phillip Island four years ago when Adriana asked him to sign her stomach.
In March, Stoner won the opening race of the MotoGP championship in Qatar, forcing Valentino Rossi, the sport's biggest name, to settle for second place.
It was no fluke. Stoner has now won eight of 14 races this year and enters the Japanese Grand Prix tomorrow (Midday, 12:00 pm Thai time) having virtually lapped the field. But if you're thinking he is an overnight sensation, think again.
This little desktop engine produces real exhaust noise, and it is the latest motorcycle engine gimmick and it runs on unleaded 98 or better USB computer power.
I belief that the company who makes them makes two models Kawasaki 'W1' and triumph 'T120 motorcycle engine. This little engines give motorbike riders the feeling of the open road during the long days as office slaves, the little Motorcycle Engine is a single vertical cylinder engine type. When the USB cable is inserted in the USB port, the piston drives bangs with USB bus power, you will hear engine sounds and the little bugger moves like he needs to go.
If sound and the feeling of the engine movement not foul you, then you in for a surprise the engine produces the right vibration it feels like you have a real engine on your desktop, this gimmick is a sure need for any motorcycle lover who necessarily needs to stay in the office the whole day.
Rizla Suzuki's Cal Crutchlow set the third fastest time in the dry morning practice before the rain fell in the afternoon at the 12th round of the Bennetts British Superbike Championship at Donington Park in Derbyshire.
He was just 2/10ths of a second behind the fastest rider in the morning and while the second session started dry the rain started to fall with just under half-an-hour remaining, scuppering his chances to improve. He was seventh fastest in the weather interrupted afternoon practice.
'I'm very happy with my pace in the dry," explained Cal. "I started with my Rizla Suzuki set up exactly as I left it at Cadwell Park and tried a couple of tyres this morning. It was extremely windy so I had to be careful. In the afternoon I started on a used tyre with softer suspension and it was comfortable but never had a chance to try fresh rubber and go for a lap time before the rain fell.'
In some previous story, the tuning of a carburetor, I talked about using a Dyno, we got several reactions about this. A Dyno by motorcycle mechanics or dynamometer for English Professors, is a machine used to measure torque and rotational speed (rpm) from which power produced by an engine.
Okay this Dyno's are not something you would buy just to tune your carburetor, hence it is cheaper to visit multiple motorcycle tuning shops, until you have the right performance.
So if you don't have free access to a dynamometer, don't worry, I did years without also. With a stopwatch, tachometer, and some imagination you, too, can measure the power output of your engine accurately enough to get your carburetor dialed in correctly.
Consistency is the key to these types of performance tests. When doing any of these tests take into account air temperature and humidity.
Scorching sunshine welcomed the MotoGP paddock to Motegi today as the fifteenth round of the season got underway at the Japanese track. Temperatures reached a maximum of 34 degrees during this afternoon's free practice and it was a difficult day's work for the riders and teams alike, with Fiat Yamaha pair Colin Edwards and Valentino Rossi finishing the day 11th and 14th respectively in the combined standings, which were topped by Dani Pedrosa.
Just five days after his spectacular victory in Portugal, Rossi got off to a less auspicious start today, finishing the morning session fifth but dropping to fourteenth this afternoon after his number one bike suffered a technical problem and he was forced to complete the hour on his second machine. Edwards meanwhile did not fare much better, finding himself down in 13th this morning and climbing just two places in the second session, despite making some improvements to his set-up this afternoon.
Rizla Suzuki is ready and raring to go racing at the penultimate round of the 2007 Bennetts British Superbike Championship at Donington Park in Derbyshire this weekend after a three-and-a-half week break from track action.
Cal Crutchlow piloted his Rizla Suzuki GSX-R1000 to his best ever Superbike results at Cadwell Park at the last round in August with a fourth and fifth and is looking to make the elusive step onto the podium at the challenging 2.5-mile long Donington Park.
"I feel that I am riding better than ever and my Rizla Suzuki is doing everything I want," explained Cal. "For the last few rounds we have made very few changes and my results have been getting better and I think it will be more of the same this time out. I want a podium finish before the end of the season and will be doing all I can to achieve it at Donington Park."
