Introduction: The carburetor is paramount on the 2-stroke engine, which is why the team RRD decided to sell only genuine INC sprinkler certified by dellorto certainly more expensive but it has been proven by various tests that the nozzles (adaptable , copies ...) create a power loss, bad starts, not age well, offer poor performance, the numbers are sometimes unreadable, poor machining adapting evil forms of needles ... true dellorto sprinklers are engraved INC proof of quality, durability and performance. They use a specific pattern machining, the best metals and the best machines. Thank you for your compréhension.Nous recommend tuning the engine only once honed as it takes full throttle and push the engine in the towers. For break, you better go up a little bit bigger to lubricate the engine.
Description: The main jet comes into action all the time except at idle, is its size which defines the amount of gasoline that will blend looks, giving the carburetor: the gas mixture, of course, a carburetor biggest possible to take more air so getting fatter nozzle and therefore, more gas mixture = better filling and more performance. Ditto for the air filter, filter taking more air = larger nozzle and therefore more gas mixture for performance.
These nozzles are mounted on the carburetors dellorto (DELL'ORTO) PHBH, PHF, PHM, VHSB, VHSB Racing VHSC and VHSH
The nozzle adjustment is critical in controlling a motor is determined by him your power and longevity. As soon as you change any item, check its settings. To solve it you will first adjust the idling jet and nearly set the wealth tighten thoroughly wealth screw (with great moderation) then loosen ¼ see 1.5 rounds towers. For the needle must be notched banal to the middle. Then start with a normal spray and a cold-type spark plug NGK B8 and B9, DENSO / MALOSSI W27 or even original for testing. We can not stress enough that the candle too cold B10 do not offer a good enough car for cleaning quickly and correctly perform carburetion settings! The nozzle size varied according to the airbox, engine, horn ... So on generally new carburetors are delivered with the proper nozzle at the beginning. After your short test ride, check the color of your candle.
WHITE OR GREY = Nozzle too small because the engine takes too much air and too much can fuel: risk of tightening
BRICK / BROWN / CHOCOLATE / ORANGE = excellent gas mixture / durability and power
BLACK / GRAS = Nozzle too large: risk gumming / power loss
Sélectionez the desired size before purchase.
