Регулировка карбюратор Стелс 500

Регулировка карбюратор Стелс 500

Большинство двигателей современных автомобилей комплектуется системами впрыска топлива. Но при использовании на мототехнике преимущества подобного оснащения неочевидны. Именно поэтому многие производители квадроциклов по-прежнему устанавливают на свою продукцию карбюраторы. Такой подход вполне оправдан, при условии, что деталь изготовлена качественно, а регулировка качества топливной смеси и оборотов произведена правильно.

Get gas into the carb

Open the tank and check the fuel level. Most carbureted motorcycles do not have a fuel gauge.

From there, the fuel tap (petcock) has to allow fuel to flow. Often you’ll see three positions marked on a petcock: “ON,” “OFF,” and “RES.” The “on” position should be fine unless the fuel level is very low, in which case you’ll want to use “RES.” «RES» is reserve, a spot on the petcock that draws fuel from the very lowest point in the tank. If you’re not sure if there’s enough motion-lotion in the tank, use «RES.» (Or, to save your time, just put some gas in it and use «ON.» You gotta put gas in there some time.) If they’re not labeled, or there’s just a knob like on a Sportster’s «winged» petcock, make sure the knob runs parallel with the direction the outlet faces to open it.

PetcockHere’s a winged petcock. Note that the wings of the normal flow (front) and reserve (facing the camera) are both perpendicular to the bottom-facing outlet — indicating this petcock is off. RevZilla photo.

Other bikes may have “PRI” instead of “ON.” You can use either setting, but the prime function is really just a way to get fuel into the bowl of a bike equipped with a vacuum petcock; that’s a petcock that turns on and off automatically. (That’s the theory, anyway. I hate the damn things and retrofit everything to a normal gravity feed valve.) Older Harley Big Twins (pre-1965) have a petcock on the top of the left tank; that needs to be unscrewed. (Or unscrewed and lifted, if you’re looking for the reserve in the case of a bike with empty tanks.) And if you are working with an unmarked aftermarket unit, usually when the lever is in-line with the petcock’s outlet, you’re flowing fuel in the “ON” position.
