On, Off, and Reserve switch?

[benjamin247]

When do I switch the gas switch from ON to RES or OFF?

Sorry for the noob question....

Turn the gas ON when you've got a full tank and are going to ride. Turn the gas OFF when you plan on parking the bike for a while. Turn the gas to RES(ERVE) when you run out of gas and need to make it back to camp.

Thanks whrecked.

Does RES use less gas? I'm wondering if I should keep it on RES if I'm just going around town and conserve gas.

No does not use less gas just uses the bottom of the fuel tank. It basically is like your fuel light coming on it is there to prevent you from running dry when you don't have a fuel gauge.

when in the ON position, the fuel level will go down to a certain point and then the bike will stop even though there is still fuel in the tank, then switch to reserve and it will use the bottom e.g. 1.5 litres of the tank, to get home/back to camp. it is 'reserved' fuel for this reason, so u are not stuck out in the middle of nowhere. like DontRoostMe said and is basically and indication that u are low on fuel and u should get back to camp/home asap.

A picture might help.. as stated, when 'on' the fuel comes thru the longer pipe. Once you run the tank down past that point, you can flip it to 'reserve' which will drain the lower part of the tank.

If you put it on 'reserve' all the time, then when you run out, you're done!

you'll know when you're running out of gas when the bike begins idling lower, has poorer throttle response (particularly fast throttle changes) and sputters. this is when you switch to the reserve supply. it's good to practice changing the petcock position while you're moving, although that's a more practical skill for street riding/motorcycles, unless if you're in a race that is.

i turn the fuel valve off if i'm going to leave the bike to sit for more than a few minutes. of course when you put it away after riding you should keep the valve turned off.

if your on a 2 stroke, it will run lean and can cause a runaway too, which is when your engine revs uncontrollably because the lean mixture is causing extra heat which causes it to detonate before it sparks

Ah...got it. Thanks everyone!
