One line that comes from the top LH side of carb (looking at carb w/o air cleaner) is a carb vent aprox 1/4 " hose. It connects only to the carb & hangs in a wire bracket as a vent tube. The 1/2 " vent line that goes from the valve cover on the rear cylinder goes to the spigot on the air cleaner case & vents the crankcase gases back into the intake of the carb to be burnt. Those are the only 2 lines other than the fuel line that comes from the metal pipe that crosses over to the fuel pump on the other side of bike. That fuel line connects to the carb metal fuel spigot on the side of the carb. That's fuel into carb.

SOURCE: vaccum line routing on the carburetors of a 1985 yamaha xj700

There's only two , on the Ca. model , sitting on the bike second cylinder from left, the synching port goes to the petcock -on the carb joint nearest the block- It would be the only boot without a black cap n a spring clamp .And (it'll be a long hose) goes to the emissions can behind the air box on the right from the carb itself.(it has a plastic cover over it) Anything behind the carbs (between 1n2 then 3n4 ) is over flow tubes to the bottom of the frame.

SOURCE: 1985 Yamaha xj700 Maxim- Carb. fuel lines

yes, the breather line hooks to the petcock on the line facing the back, the fuel line hooks to the larger one. the line from the breather is actually a vacume line that turns on the fuel, without it you will not get fuel out of the petcock unless it is in the prime position.

SOURCE: How do you check the oil in a 2003 yamaha roadstar

all bike are to be checked in the upright position! then find out how much the bike takes from your manual if you dont have a manual ...do the following ..when you just change oil and not filter you will be adding less oil,"almost" all bikes take @ 3 quarts oil minimum, so what i do to be safe!! is always after draining is put in two quarts no problem, but with the third bottle i only pour in half.. drop oil cap back on and start the bike and let it run for a minute, the turn it back off, then check oil level, if it doesn't register anything on the stick or sight glass then your o.k. to add the rest. now take a reading, and only fill to almost full, i always under fill my bikes, because over filling will cause damage to internal bearing by the air bubbles from the splashing of the crank in the oil pan. Same as cars.
If you found this helpful can i get a rating?
Thanks

SOURCE: My 2001 yamaha roadstar makes a clicking noise

When you push the starter button you hear a click , so you know the button is working. Follow the positive battery cable to the starter solenoid. Take a wire and jump the two posts on the solenoid or touch the two cables together. If your starter works, then you need a new solenoid. If you hold the starter button and tap on the starter with a plastic hammer and the starter works you need new starter brushes. Anything else wrong with the starter and you need to replace the starter assembly , the manufacturer does not make replacement parts for the starter.

SOURCE: Working on a friends 81

The petcock on these bikes is vacuum operated, which means that there are two hoses that go to it. The thicker hose is the fuel line and it runs from the thick port on the petcock to the fuel input on the carburetor rack. The fuel input on the carburetors is located between the number two and number three carburetor bodies. If you aren't sure which is the fuel connection, just turn the petcock switch to prime for a second and you will see gas come out of the fuel connection.

The thinner hose on the petcock is a vacuum line. It runs from the vacuum port on the #3 cylinder (between the carburetor body and the engine) up to the smaller connection on your petcock. When the engine is turning vacuum is applied to this thinner line and allows fuel to run from the tank into the carburetors.

There are the only two lines that should run to your petcock, and the fuel line should not be split anywhere between the petcock and the carburetors.

Good Luck,
-Josh

79 yamaha XS 750 crank no start


well here goes your problem probably in the float bowl area water sediment blocked low speed jets if you do not want to do a complete tearmore down just clean the jets and float bowl.
Use a carb cleaner soak the jets make sure you can see through them the small low speed jets specially.
if you have access to air blow the jets clean.
spray any passage ways with carb cleaner reassemble good luck.

I am having running problems with my 2004 Yamaha Roadstar. I drove the bike at spring break 2009. Bike sat until yesterday. I tried to start it but the battery was dead and the gas was bad. Recharged the...


You have done a good job ... pat yourself on the back ... following that, go get some injector cleaner and add an appropriate amount to your tank and go for a ride. Do what ever you need to do to keep from pushing it home. I think this will solve your trouble.

May I recommend a fuel stabilizer for your fuel for future periods of time when you will not be riding? StaBil is a good brand but there are others as well.

Have installed hypercharger on 06 roadstar. lost 15 miles per gallon. how can i get some of that back ? roadstar has stock pipes with kuryakyn hypercharger installed. carb rejetted for stock pipes


Take the hypercharger back off. The carb uses fuel according to how much air sucks through. You are putting alot more air through the carb, so it sucks more fuel into the engine. Even if your not burning all the fuel, it's running through anyway. That's the downfall to a carb.

Carb puking gas


I had this same problem. What I discovered was the float needs adjusted on the carb. I set mine lower inthe bowl and it stopped the leaking. Reason for this happening is on hot days the fuel in the bowl will boil. This boiling action dumps in more fuel and the carb spits it out the air breather.

Sudden high acceleration


Either a vacuum hose is hooked up wrong or a vacuum leak. Also make sure it's not leaking around the carb base. You can spray carb cleaner around the base while the engine is running. If the rpms drop then you know you have a leak there. Dont spray a lot, just enough to wet the area some.

If you have to stock Hitachi carb its a miss or go when have one rebuilt or buy one rebuilt. There's no new ones out there unless you got really really really lucky. There's only so much of the carb that can be replaced (usually never the electrical compononts) and if it was ever rebuilt correctly.
