Lin Jarvis: “With Valentino, Ducati will be a formidable opponent”
Lin Jarvis between Jorge Lorenzo and Valentino Rossi.
(…) “After seven seasons as successful, do not you fear to arrive today at the end of a cycle?
I’m not saying the result will be easy, but we have no reason to be really worried. Rossi is true that before we were a bit lost. In fact, Yamaha has gone astray after the accident at the end of 1993 Wayne Rainey. Confidence and passion then disappeared, and it took over ten years to found the right path. That said, since 2003, MotoGP has become a very important part of business Yamaha, and I am confident that we will not repeat the mistakes of the past. I’m not so far as it will be easy because the competition is fierce. Valentino, Ducati will be a formidable opponent. Read the rest of this entry »
A mixture is measured on the relationship between air mass and mass of fuel, more balanced relationship is called stoichiometric (value 14.7), with lower values results in a mixture “lean” or “poor”, with higher values have a mixture “fat” or “rich”. After the trial period, the rich mixture is preferably used, because it presses the motor to extend the speed and then to go out more. It should be used a mixture that is neither too fat nor too thin, because both can seriously damage the motor of the mini.
The mixture too rich could flood the engine and cause problems start, the lean does not ensure proper lubrication of various components. The break is the time when you are 3 / 4 fuel supplies to the minimoto, minimoto here settles well.
At the beginning you should not run at full throttle, it could be damaged. The structure should be checked: brakes, fork, tires. All mini bikes have a clutch that standard should be kept as it is delivered, but you can also change the clutch, putting an adjustable according to the needs of performing pilot. For the development of the engine it will take several attempts, errors and patience. Do not forget to check out candles when you buy the mini candle is white (ceramic is out).
When the candle becomes amber means that the motor is used well. If it is gray or white, there may be problems: maybe the mixture is lean. They mean trouble ahead, even traces of oil and a black, a mixture too rich. Each bike has a mini air filter (filters the air going into the carburetor), which is standard.
We must always keep these filters clean (removing the hull at the bottom of the pocket bike), not to stifle the engine. The tires are very important: those of the mini are full of air (air), the pressure should be checked.
The braking system is used to record: push coincides with the right front wheel, the lever to the left rear wheel. We must ensure sufficient braking but not restricted, dangerous because it enhances the wheels from locking while braking destabilizing the half.
You can do it yourself all maintenance of your mini, but you should ask an expert for the more sensitive issues to be addressed, not to do “damage.”
Security on minibike
A pocket bike is always a two-wheeler and must be very careful not to create danger for themselves and for others. It seems banal to say it, but you should use a helmet, preferably full, always. Different matter when you race so do not forget the strict protections on the elbows, shoulders, back and knees. Falling is easy and even break something. There is need for adequate clothing, such as overalls and gloves.
The mini must follow the same rules that apply to driving on mopeds and motorcycles, in fact for the Highway Code, “a vehicle is any motor driven by the man on the street, with certain minimum requirements and measures, including speed, than 6 km / h “. The mini guide and those who are subject to the same bureaucratic rules and behavior of mopeds, as defined by art. 97 of the Highway Code, or of motor vehicles in accordance with Art. 93 of the CdS.
