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.

Hi,

The volume of oil is calculated by air gap. This is proportional to your weight.
BUT to make life easy, 380 to 400 ml gives a good ride across the board.

If you are planning to race the bike, I would sugest letting a pro do the suspention for you.
Although it's not rocket science, it takes a lot of experience to get it perfect.

Enjoy the ride

poor some water on it

i run mine 50:1, if i go 32:1 it doent burn clean and drips out the pipe

Check gas cap vent by running with cap loose.If this clears it up go with a new cap and vent hose.If not check the engine compression.

sounds like you need a new power valve in the cylinder. They can go bad and thats how they will act. You have to take the cylinder off to change it. If your that far you might as well put a new piston and ring in it.

Sometimes you need input rotation to properly align gears spin the crankshaft a little then try.

Are you sure the torque specs posted are correct? They seem a little strange to me

Here's how I'd try to fix the clutch: 1.) Try to adjust the cable at the handlebar; usually there's a little bid of clutch lever travel (like 1/4"-1/2") before the clutch disengages. For right now, adjust the clutch so that there isn't any play and the adjustment all the way out. If the clutch disengages the transmission, then you know you have to fiddle with the cable to get it adjusted properly. 2.) The clutch plates could be sticking: here you'd have to take the clutch cover off and get to the clutch. Remove the clutch (usually an impact is ideal for removing the clutch holding nut. Take the clutch apart (steels and clutches), make sure they aren't sticking together. Then dip the clutches in oil, then reassemble. 3.) Sometimes the clutch basket (holds all of the clutches and steels in a "basket") gets grooves in it. These grooves prevent the clutch from disengaging. Sometimes you can file the clutch basket fingers down to remove the grooves. Alternatively, if the clutch basket fingers are really worn, you may have to replace the clutch basket. Typically, when your in the clutch side of the engine case, I'd examine 2 and 3 (above) at the same time.

check for the fuel filter in the bottom of the gas tank attached directly to the outlet

most ignition problems are simple 3 parts - fuel / fire / air from everything you've already worked on, it seems you must set your IGNITION to FIRE on time at higher rpm .

First, did it break or is it bent or is it stripped? These all require different approaches once you get the right side of the engine clear, clutch removed, etc... TAKE PICTURES WHILE YOU ARE DOING THIS to make sure you put everything back where it belongs. Do you have a clutch hub holder? (IMPORTANT) Do you have a air wrench, you will have a large clutch nut (24-26MM?) to remove and then reinstall the nut with the correct torque! If you do not have these tools, PLEASE take it to a PROFESSIONAL. He will have all the tools necessary. If the shift shaft is broke or bent it is going to be more difficult because it is a tight fit through the engine cases, they are aluminum and they will break if the shaft is forced out!! You will have to carefully saw the shaft off CLOSE to the case as possible before attempting to remove it. If its just stripped, it can be filed or sanded down, cleaned, and removed easily. Change the shift shaft seal too!!! If this is your first time to try this... and you don't have any of the tools I mentioned, PLEASE take it to a professional!!

Bent shift fork is your problem.1st and 2nd working fine,wont go into 3rd,replace the shift fork and stop being so hard on the shifter.Costs a lot of money to fix these toys.

Hi, i am sorry but you dont say what the model of your machine is, this would help me determing the correct, answers for your questions, most kickstart springs can be changed by simply removing the clutch cover followed by the kickstarter shaft and then replacing the spring, make a note of kickstart stop location carefully remove the shaft holding the gears together replace the spring followed by the. Replacing the shaft and tensioning the spring before cover replacment, oil,etc. Some machines the shaft and spring is inside the centre cases and a complete engine strip is ness

sounds like a air leak. check the gasket around the reed block

A weld will ruin the temper of the metal, it will fail. A rim that cracked probably is weak elsewhere.

i promise u its the carb buy the whole unit

I am not sure what you mean on the "running fast" statement. If idle speed then turn the idle screw outward to slow down the idle.

The backfire is caused by turning off the ignition key when the bike is at high revs. let it idle down THEN turn it off. The backfire is there because the carb idle circuit is active anytime the piston is in motion. Gas goes into the cylinder as the bike revs down then a hot spot in the exhaust pipe finally ignites the built up gas. There is your backfire.

Is the running fast question answered? Give me more information on the problem if it isn't.

Please rate this answer. Thanks njv6!
