As far as the breather to the top of the engine goes, just pull off the hose and replace it with a small breather filter and you are good to go. Sorry, but can't help with your vaccum diagram.

not that familiar w/Yamaha,but disconnected vacuum hoses may connect to fuel petcock at tank.I know Honda uses a system that only allows fuel to flow when vacuum is supplied.

Some articles I have read suggest removing the stock auto-choke carb and replacing it with a Honda CT70 Carb. Check with a local shop to verify, I do not own either and am just passing along the info.

Another solution suggested by 'OneRide': Try it with the gas cap off. The tank vent might be plugged. Possibly plugged fuel filter. Are you using the choke correctly?

This seems to be a very common problem and no 'one' solution to fix it.

I hope this helps.

My 2004 Honda civic won't start. It will start fine minute then I will run into the store and it won't start. It acts like it is starving for gas. If I wait a while it will start.

Check the fuel filter. Air cleaner. Vacuum lines and fuel pump. And all fuses. Make sure the gas cap is venting and dont trust the fuel gauge fill it up.

I have a manual 05 tiida.The problems I am having are the starting of the car can take 5-10 mins at times to crank over and also when driving in lower gears the car acts like it is starving for fuel

Several GM cars of mine had check valve in fuel filter. I stopped the delay in cranking by changing the fuel filter. I think Nissan fuel pressure regulator act as a check valve. The issue of it taking a while to crank sounds like the gas may be running back to the tank and you have to pump the air out of the line before it cranks. Just a thought to look at, fuel pressure regulator.

I have a 2005 Arctic Cat 500 that will crank and run great. Push the throttle acts starving for gas. I have replaced the fuel filter, fuel line, and cleaned the tank. Also replaced carb. NEED HELP!

Try running it with the cap off the tank. Sometimes the cap will fail and wont allow air back into the tank when you draw fuel from it. This starves the engine of fuel.

My 2000 kawasaki Zrx 1100 has gas coming to my air box vent hose wit would cause that

You need to describe better what you are calling your airbox vent. It sounds like there is a drain hole or port in the airbox to drain away raw fuel that might get in there by flooding. If so it is fuel system overflow or floodign that is causing raw fuel to be in the airbox.

My 2000 kawasaki zrx 1100 will crank an run on choke but die when I take it off choke

If you have a choke you have a carb(s). If it will only run on choke the low speed circuit is likely dirty/plugged. If it will run at medium or higher throttle on choke only you may have further carb pluggin gproblems and/or a plugged fuel filter or pinched line etc.

Gas leak for kawasaki zrx 1100. What might some reasons be?

Check all your fuel lines, make sure that they haven't perished. Also check all your fuel hose connectors make sure they are tight not constricting. If you have to tighten your hose clamps so tight that the pipe bulges, then your fuel hose is junk. If you only have those spring clips, get rid of them and put decent hose clamps on.
Take off your seat, and locate the breather pipe at the back of your tank. Make sure that this pipe is not blocked, if it is you'll get a pressure build up in your tank.
Check your air filter element, if it is clogged you will have an over powering fuel smell and you may even have weeping of fuel vapours as it condenses.
Check all your vacuum hoses make sure they are in good condition.
If you have a fuel tap sometimes they don't seal correctly and weep fuel.

My mower seems to have low fuel pressure. Gas filter is new, lines are clear but sometimes the engine starves for fuel. The filter has almost no gas showing in the clear globe when running. Is the black...

Yes it is a vacuum fuel pump. Remove the line to the carburetor and place a clear container to catch fuel. Crank the engine and watch to see how much fuel is being pumped. It could either be a weak fuel pump or the pickup line in the fuel tank is starting to rot, depends on how old the mower is. The pickup line in the fuel tank is rubber, and sitting in fuel for many years can break the line down causing it to fall apart. It should be noticeable more if the fuel tank is below 1/2 tank. Hope this helps, Daniel.

Replace the fuel pump and fuel filter to correct the problem you are having. Without the proper fuel pressure the engine will not run at all. Hope this will help you. You might check the fuse/relay panel for a blown fuse or relay in it to make sure you are getting power to fuel pump before you go to the trouble of removing the pump and fuel filter. Hope this will help you.

Rough running

This problem, ironically, might simply be the screen filter on the in tank petcock. The zrx is a gravity fed filter-less fuel system with only the screen to act as a filter. I had the same problem with my black 2001 zrx and did a full tune up before pulling the petcock and cleaning away 9 years of sediment from what appeared to be a very clean tank. I simply purchased a seal kit from Kawasaki before the tear down and waited till the tank was as empty as it would get by riding it. The screen was surprisingly clogged with junk...and once cleaned and reinstalled the bike no longer ran poorly when cold. Im not sure why the bike being warmed up made a difference but it it starts and runs like a champ (colod or hot)!!!
