You can not turn off the gas at the petcock, you leave it in the turned to the bottom position all the time. You only use prime position after it sits for a few months and of course the reserve when you are running low on fuel.

It ran out of gas put new gas in and now wont even turn over everything turns on but nothing when i hit the switch

Hi Dick and the usual suspects are:
1. Ignition switch not in the "ON" position.
2. Engine run switch in the "OFF" position.
3. Discharged battery, loose, corroded or broken battery cables, especially the "NEGATIVE" cable at both ends (solenoid chatters).
4. Bank angle sensor tripped and ignition/light key switch not cycled to the "OFF" position and then back to the "ON" position.
5. Security alarm needs a reset.
6. Starter control circuit, relay, or solenoid faulty.
7. Electric starter shaft pinion gear is not engaging or over-running starter clutch slipping.
Good luck and have nice a day.

What position should the fule petcock be in when running. vertical or horizontal?

It can depend on the type of bike but usually verticle or down. Straight down (6 o'clock position) -- Normal
- keep at normal position when bike is on and off unless special circumstances require use of the following two positions.
3 o'clock position -- Prime
. - use if you need a steady unrestricted gas feed/flow, usually used when there's trouble starting or gas line was disconnected, etc...basically whenever you feel there's need to use it ( beware it can flood the engine as well as leak if left on too long
9 o'clock position - Reserve
. - usually used when running low on gas, helps get the last bit of gas to make it to a gas station....ive also used Prime in some instances when I ran low on gas and the bike wasnt getting enough gas in the normal position.

Hope this info helps,
safe riding - Shays

Change battery in Stratoliner

You didnt say if it is a cruiser or street so here is both:
  1. Cruiser
    • 1 Remove the seat from your motorcycle. Turn the key to the "On" position and hold it there as you lift up on the seat to unlock it.
    • 2 Put on the gloves and the safety glasses. Remove the plastic cover on the battery compartment.
    • 3 Detach the cables connected to the terminals on the top of the battery. You can pull the cables off by hand. Remove the negative (black) cable first, then the positive (red) cable. Cover the negative battery terminal with black electrical tape.
    • 4 Lift the battery out of the compartment. Be sure not to touch the terminals to any metal components of the frame or the seat.
    • 5 Position the new battery. Connect the positive cable to the battery first, then the negative cable.
    • 6 Reattach the seat.
    Street Bike
    • 1 Lift or remove the seat on your bike. Use the ignition key to unlock the mechanism holding the seat in place. Depending on the model, tilt the seat back or lift it completely off the bike.
    • 2 Locate the two anchor bolts on either side of the gas tank. Unscrew the bolts using an Allen wrench. Hold on to both the bolts and the bushings on the underside of the bolts. The bushings prevent your gas tank from rattling during operation.
    • 3 Tilt your gas tank up to reveal the battery compartment. It is necessary to prop up the gas tank or have a helper hold it for you as you work on the battery.
    • 4 Detach the cables connected to the battery terminals. Remove the negative (black) cable first, then the positive (red) cable. Cover the negative battery terminal with black electrical tape.
    • 5 Lift the battery out of the bike, being careful not to touch the terminals to any part of the motorcycle or your skin.
    • 6 Position the new battery in the bike. Connect the positive cable to the battery first, then the negative cable.
    • 7 Reposition the gas tank and secure it by tightening the bolts.
    • 8 Close or reattach the seat

fuel lever should be set to on. When you run out of gas in the on position then you switch to reserve. Turn the gas valve to off when not riding

2001 TW 200: i got the bike to start it ran for about 1 min the...

Make sure you've covered the basics: fuel petcock should be in the "on" position; ignition must be in "on" position; kill switch must be in the "run" position; bike should be in neutral. Make sure there's fresh gas in the tank. Check the oil through the sight glass on the right side of the engine, with the motorcycle balanced and level. Check the spark by taking out the plug and holding against the engine while you crank the starter. There should be a blue spark that appears with every second revolution of the engine. Check the gas flow by pulling the gas tube off the carb and turning on the petcock under the gas tank. Gas should flow freely from the tube. If all of these tests check out okay, you may have a carburetor problem, such as a plugged jet. This is quite common if the bike hasn't been used for some time. Removing the carb and cleaning it isn't overly daunting. Check the TW200 forum at There's lots of info there. Also, download a copy of the shop manual. Good luck.

Positions "Reserveswitch"

The On position is where you run the bike after filling the tank. The Res position is when you are almost out of fuel and the motor stutters you turn the switch it it and that will give you about 1/2 a gallon of gas left in the tank to get to a gas station and refill. Pri is for priming the carbs only. If you have ran out of gas after using the reserve fuel you switch it to this position to fill the float bowls with fuel. Do this for only 30 seconds and switch it back to On position.

Just wanted to determine, for a Kawasaki bayou 220, the fuel lever positions for fuel Off VS On (ON = vertical?).

The valve is open when the lever and valve are parallel. Generally that is down. When the lever is pointing across the valve it is closed. Think T vs. I. If the lever and valve cross it's closed, if they go the same way it's open.

That applies to a two position valve, if your Bayou has a reserve postion it could be different. That would be three positions and across one way would be open, down would be reserve, and across the other way would be closed. Should be marked on the petcock if that is the case.

Fuel switch

The fuel switch has three positions:
The arrow on the handle points to the position selected.

ON = Normal operation setting. Fuel will not flow through the hose to the carb until the engine is on. Gas in the carb bowl is used to start the engine. The arrow is DOWN when in the on position.

PRI = Fuel flows through the hose to the carb at all times. This setting is used if the bike has been sitting around and the fuel level in the carb may be too low to start the engine. For safety use this setting only to fill the carb bowl with gas or for brief testing.

RES = If you run out of gas, this setting will provide extra gas so you can hopefully find more.
