I had the same issue with mine, just recently purchased the bike, previous owner said it ran but has been in storage a year and a half. I filled the fuel filter and everything and it would **** down the fuel but never even attempted to fire. I came to find out that there are two lines that come off the tank, the one without the fuel filter has a vacuum on it. So what we did was pour a little fuel down that line to prime the engine because it dumps fuel straight between the carb and cylinder. Took about 3-4 attempts but it fired and ran, just had to set the idle from there. Hope that helps you.

    You are awesome...That is exactly what it took to get it started. I have a Yamaha Maxim and it was in storage for 3 years. I knew the carbs were gummed up so I did clean them, but when I put them back on the bike it wouldn't start. I poured some gas in the vacuum line and it instantly started and ran perfect. You Rock!!!. Thanks

Large line is fuel, from tank to petcock. Large line from petcock to Carb. small line is vacumn from intake manifold to petcock (small spigot). suck on this line & make sure Gas comes through Large line to Carb.

Its a 1985 Yamaha xj700 maxim that has a problem with the fuel and vacuum line, from the fuel tank to carburetors and drain line diagrams

Hi, Sevensons7 always check fuel flow first to isolate the problem area otherwise the usual suspects are:
1. Fuel tank empty.
2. Fuel cap or fuel tank not venting properly.
3. Fuel filter clogged with rust or dirt.
4. Fuel valve/petcock not in the on or reserve position.
5. Vacuum line to fuel valve cracked, broken, pinched, or missing*
6. Fuel valve/petcock clogged or diaphragm cracked, cut or torn*
7. Fuel line from the fuel valve to the carburetor or fuel pump clogged, cracked, pinched, bent, broken, or missing.
8. Fuel pump not working*
9. Fuel line touching cylinder or head causing fuel to boil and vapor lock, repair by rerouting and wrapping line with convoluted tubing.
10. Carburetor inlet clogged.
11. Carburetor float or needle and seat stuck.
12. Carburetor not venting properly overflow line or bowl fitting clogged, pinched, or bent.
* If equipped or applicable.

Bike sat for a long time with fuel in tank. Tank was previously sealed. I changed spark plugs, tore apart and cleaned carbs. It will only start for a few seconds if i spray starting flued in the air...

stored gasoline begins to deteriorate/lose octane/after only two weeks.drain fuel tank label and disconnect fuel lines at petcock,remove petcock from tank,clean fuel,check for supply to carbs. Honda's of that vintage have a seperate 'reserve' tank under the battery,which tends to collect all the 'crud',and must also be purged.trace your fuel lines to see if your unit is so equipped,

I need to know where all the hook ups go coming from the shut off valve of the gas tank on my 1985 yamaha maxim x 700

There are two lines coming out of the fuel petcock (shut-off valve). The small diameter one is a vacum line that connects to the top of the rubber intake located between the carb and the engine head. you should notice that all four intakes have a vacum port in this location and they should all be capped excet one - usually #2.

The second line of the fuel petcock is the larger diameter one, and is the fuel line. Make sure you install an in-line filter if it has been lost. The fuel line connects to the carb on a pipe that feeds all four carbs. The pipe is located on the lower portion of the carb, down by the float bowls. There will be a connection port between #2 and #3 (right in the middle of the carb assembly). It will be difficult to see when everything is assembled and even more dificult to reach.

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.

1985 Yamaha XJ700 Maxim won't work

All engines need the same three to four things to work correctly..
Compression, Fuel, Spark, (timing).... But, usually those bikes, have fuel issues. The fuel tank spigot has a vacuum controlled valve which when the engine is cranked, suction is applied and fuel then can flow. Second,, the needle and float in the carb tend to get gummed up along with the main and idle jet... You need to make sure the carb is maticulously clean, Using carb cleaner, and tag wire,, or a piece of fine wire ( be careful not to enlarge the tiny holes). Keep refering to the 3-4 list fuel, compression, Spark,,,timing.....
Good luck...!!
