Jetting means

[UNITED_BANSHEE_10]

My friend just bought a banshee 06, and hes asking me about eveything part of shee, what is it and what it does. I explained everything to him but there are some that he didnt understand and im fedd up of explaining. Could you give me your explaination of these words. He might understand in a different way.

 

Jetting:

Carbs:

Pistins:

Porting:

 

Thanks, you pple are life savers and there are pple that make me so angry like him my friend

for jetting click benbb's jetting FAQ in my signature. It'll explain carbs too. For some basic 2 stroke theory, just do a google search. There's tons of websites out there.

tell him that jets control the mixture of air and fuel that go into your carbs. your jetting is the size of the jets you have and you need to change your jets depending on your elevation and temperature because depending on those your engine will need more fuel or air.

 

carbs suck in air and gas, mix them together and sends it into the cylinders. with the help of reeds it is atomized, goes into the cylinder gets compressed fires bing bang boom your engine revs when you hit the throttle because you are opening your carb slides which brings in the air and fuel.

 

The pistons are what move up and down in the cylinders. the movement pulls the mixed gas and air from the carbs through the reeds. into the cylinders and then combusts inside the cylinder which causes causes power. the more throttle you give it the faster they go. rpms = revolutions per minute. your crank revolves which causes the pistons to move up and down.

 

porting has to do with removing material from the inside of your cylinders, reed cages, or carbs. when you grind away the metal leaving bigger ports you get more fuel and air in the cylinders which = more power.

 

i think. i dont really know what im talking about. i could be totally wrong. but from what ive gathered that sounds right. can anyone correct me?

All in all I'd say that sounds pretty good. You could make a few minor additions to what you said, but it doesn't sound like it would make a whole lot of difference, because it would be some technical details, that go beyond the basic concept.

That's more or less it. Cept that primary function of reeds is to act as check valves - only allowing the air/fuel mixture to flow into the case/cylinder and not back out through the carbs.

lol. and i was unsure the whole time. thanks for confirming me guys. but do the reeds atomize the gas and fuel too? or is that done in the carbs?

Atomization of the fuel and air takes place in the carbs. Like Wallrat said, the reeds essentially serve the same purpose as traditional intake valves do in a 4 stroke engine, however they are moved by the suction (opened) or pressure (closed) created by the movement of the pistons, as opposed to by the cam, lifters, pushrods, rockers (or cam and followers in overhead cam applications) in the basic otto cycle engine.
