1989 yamaha 750 v twin gas to carbs but not to heads

Not nesacerally....the carbs could b gummed up.could have bad gas (water in gas).or a fowled spark plug...

good start on cleaning things BUT, you should replace pump. the pump will have the same gum **** the tank did. you can unhook lines and turn over to see how much fuel you get

Chances are there is a water build up in the carb float bowls. The water comes from condensation in the gas tank. Try draining the carbs. Another possibility is carburetor main jets partially plugged up. You must clean the carbs if plugged jets are found to be the problem. Please rate my answer. Thanks.

carbs have a blockage,remove and clean carbs

If you have a spark plug wrench take out the spark plug look at it if it is all wet engine is flooded with gas,dry it and clean it if it is dry its not getting gas, try putting in a new spark plug. is there gas in tank , is switch on, is gas turned off, is the tank full, is the gas old and stinky? has the tiller sat for months carb may be plugged check ,engine oil level, try a little shot of engine starting fluid or gas sprayed into carb needle valve in carb may be pluged, float in carb may be stuck. tap on carburetor good luck

Don't use cold start.it will not solve your problem.Try running it with out the air cleaners ,it may be that you have an air intake problem and not getting the right Air / fuel mixture .

better look at carb-there r 5 diff jets but its probly the mid range one-be careful here because rong ajust can hurt engine-u hav a clymer manual? library has many books on mc maintenance-sayonara

sounds like the floats are stuck. cleaning carbs should do the trick. its a good practice to start up motorcycles and let them warm up from time to time while being stored.

Check spark (Clean/replace) plugs look for good spark; check battery (bad terminals can interfere with a good ground); check air filters (not clogged that will affect fuel/air mix), check new gas (old gas varnishes in as little as 3-4 months); check carbs( drain floats and look for crud)....Gotta be one of these...process of elimination.
