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."
The Red Bull KTM Team returns to Japan this weekend pumped with confidence. The team scored victories in both classes on the famous circuit last season, the bikes are expected to do well and both Aoyama and Koyama are riding in front of their home crowd.
Last year's Grand Prix in Motegi was unforgettable for KTM. Mika Kallio out-braked newly-crowned world champion Alvaro Bautista in the last lap of the 125 cc race, celebrating his third victory of the season. Then Aoyama turned team pleasure into pure unadulterated euphoria by coming home first in the 250 cc category. "A historic day," remembers Technical Director Harald Bartol. "Of course it was our secret plan o be prepared and to do well in Motegi. Even though they don't admit this, the Japanese manufacturers are pulling out all stops to succeed at their home Grand Prix. That's what makes these two victories so valuable."
So what of 2007? First it will be an occasion for Aoyama and Koyama to excel in front of what is always an animated crowd at the spectacular 4.8 km circuit set in rolling hills about three hours north of Tokyo.
Kawasaki's Randy de Puniet will be aiming to improve upon last year's premier class outing here, when he crashed out on lap nine. In previous years, when riding in the 250cc World Championship, the Frenchman proved more than capable of conquering the circuit: scoring a couple of top ten finishes at the track. After the disappointment of last week's Portuguese Grand Prix, where a mechanical fault ended his race, de Puniet hopes for a better result at the Twin Ring on Sunday.
Anthony West is also familiar with the circuit, having raced 1000cc V-twins throughout Japan in his younger years, as well as competing in 250s, and one 500cc race, at world championship level. He also took part in an endurance race here once, his team coming second, so he's put enough laps in to know his way around. The 26-year-old Australian, who recently signed to stay with the Kawasaki squad next season, will be hoping to overcome his recent struggles with set up and show both strength and stamina this weekend.
After digging into the inner workings of several big-inch engines over the past several years, we thought it was time to see what Harley-Davidson has to offer. Along with the standard 223.52cm (88inch) Twin-Cam engine that equips most of their 2005 motorcycles, you can have a big-bore of 241.3cm (95inch) or the insane 261.62cm (103inch) stroker engine.
Having said this, we must explain that there are a few rabbit trails that you have to follow to get a big engine from Harley-Davidson.
First, if you want a 241.3cm (95inch) motor, it is only available through the Genuine Parts channel, as parts kit or as separate parts to convert an 223.52cm (88inch) Twin Cam engine. A few years ago, Harley offered these engines in special edition CVO bikes, but as of June 2005, there isn't a production bike available with the big-bore engine.
The engine's increased displacement is arrived at by increased its bore from 3 3/4inches to 3 7/8inches. This can be done by either having your stock cylinder bored out at your local bike shop (which is direct a problem in Thailand) or buying a set of big-bore cylinders from your Harley dealer.
If we look at the basics of the Yamaha Fino, it is a 115cc 4-stroke SOHC, 2 Valve, Air Cooled engine. And officially the engine is a 113.5cc engine (but guess 114cc Fino did not sounded cool enough for Yamaha marketing).
We always start our tuning / modifying with a simple study of the motorcycle, in case of the Fino, the engine is a regular visitor to our modifying shop all is this the first Yamaha Fino, the also very popular Yamaha Nouvo uses the same engine.
After we had a quick look at what the Fino is made off, we decided to not overdo ourself, as this Yamaha Fino will be mostly used by family members and collages, we surely did not wanted to forget the safety futures.
The Yamaha Fino uses a Mikumi BS25 x 1 carburetor, or Carb for the Americans, some will suggest to replace the carburetor with a more sporty one. But as we have maybe a bit more know-how, we know that the Mikumi BS25x1 carburetor can be found in much larger bikes then this 115cc Yamaha Fino scooter.
Yamaha has today confirmed that Troy Corser and Noriyuki Haga will remain with the Yamaha Motor Italia World Superbike Team in 2008.
A flamboyant and much-loved character, Haga has worked with Yamaha for many years and his WSB career highlights include second in 2000 and third title position in 2004, 2005 and 2006. Currently Haga is fighting for the 2007 title with only 41 points separating him in second place from front man Toseland, having caught up 25 points at the last round in Lausitz. With only two rounds remaining on 30th September (Vallelunga, Italy) and 7th October (Magny Cours, France) Haga is taking the fight for WSB crown all the way to the wire. So far this season he has already won four races, including taking the double win at the team's home circuit of Monza.
