Question about Yamaha TZR 250 R Motorcycles

1 Answer

My TZR 250 3ma, leaks fuel from the carburators, I had them cleaned and the float levels resetted. On the fuel tap if it is on or on reserve it gushes out the fuel. Can the tap be the problem and is there a way to modify it.

The tap is not the problem, it is working as it should. The problem is that the float needles are not shutting off the fuel as they should. Turn the gas off then remove the float bowl on one carb and check for trash in the bowl. Turn the gas back on while gently lifting the float. Now lower the float. The fuel should flow when the float is lowered and stop flowing when the float is raised. If it still flows with the float raised, turn of the gas then check to see if the mechanic forgot to install the float needle by removing the pin that mounts the float/needle assembly. Most carbs attach the float tang to the needle with a small clip. Is the clip missing? The needle can get out of position and not close properly without it. The float should be light as a feather and nothing inside rattling around. A float that doesn't float will never shut off the gas. If the float is good, disconnect the gas line at the carb then get a can of carb cleaner with a "straw" to direct the spray and stick the straw into the opening where the needle goes and spray into the hole. Trash may be holding the needle open. The spray should clear the trash out. If the float floats and there is no trash holding the float open and the needle kills the gas, the floats are way out of adjustment. Below is a generic float assembly. Please take a moment and rate my answer. Thanks! My TZR 250 3ma, leaks - tombones49_45.gif

I just replace the fuel pump,filter and carburator on my 1983 plymouth reliant.it will turn over and start but wont say started what could be the problem


Possible float is sticking in carb. Tap side of float bowl with screwdriver and see if that helps. If not, I suggest checking the float level and make sure it is adjusted at the right height.

When I turn the fuel from off to on, fuel leaks out everywhere


Do you mean at the carburator ? If so the float (controls fuel level in carburator bowl) is either sticking or leaking making the fuel flow continuously, out of carb. The float and fuel inlet needle need to be unstuck or replaced if fuel is leaking in the float itself making it heavier therefore letting in more fuel than it should. If anywhere along fuel lines, replace fuel lines. Hope this helps.

You need to remove and clean the carbureator, the needle and seat are dirty and allowing the fuel to leak by and out the overflow. A good cleaning should fix the trouble.

2003 yamaha roadstar leak fuel sometimes after I shut it off I think the floats are sticking any solutions. Rick


Yes Rick, try a couple of tricks I know.First,open the carburettor drain screw located at the base of the carburettor,this lets fuel flow out of the carburettor drain located next to/under it.(To acces this drain screw look between the engine cylinders from the LEFT of the bike)While the fuel is draining out,tap the fuel bowl.Next re-tighten the carby drain screw and see how that goes.I would suspect your bike has a vacumatic fuel tap that has 3 positions on it.1 marked on, 1 marked res, 1 marked pri.If the fuel leaks occur when in the on or res position this means part of your problem is a leaking diaphram in the fuel tap.Replace this & when engine isn't running,no fuel can flow to the carby when it's in the on or reserve positions.After ensuring the tap is ok, and trying the first trick,if it still leaks,well then you'll have to pull off the carby and give the needle and seat a clean.
Hope this healps Regards Andy Porrelli

1986 kaw 454 ltd carbs leaking gas into airbox anybody know how to fix?I had. the carbs rebulit twice. the last time at the dealer lasted about a year.any body help me.


You have float and/or needle and seat problems. Remove the hoses from the air box to each carburetor. Set bike on center stand or block up to get it level--turn on fuel tap and watch for leakage from each carburetor. Turn the fuel tap off. Pop the float bowl off of any that leaked, remove the float and pin--catch the float needle. You probably have debris in the seat area which causes faulty float action. Turn on the fuel tap again and catch the discharge in a clean small jar. Look for rust or other particles in the fuel. If all carburetors are affected, look at the fuel strainer screen just above the fuel tap bowl--no holes and seated properly. You may need to flush the tank if the interior is rusted or full of dirty fuel.
