Probably a plugged up filter screen in the gas tank petcock (gas valve). Drain the gas then remove the petcock and clean the wire mesh filter. Your bike is getting old and rust accumulates in the tank. You may want to get a liquid tank liner to lock the rust in place and so the tank won't rust anymore. Install an in-line fuel filter as well. A site for the tank liner is below.

Google kreem fuel tank liner “ or go to www.http://www.4secondsflat.com/Fuel_Tank_Sealer.html

Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the
carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the
carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.

Please rate this solution. Thanks!

    Scratch the answer I gave if your 1976 bike has fuel injection. Just go with the plugged screen, fuel tank liner, and water trap bowl.

Caliber 115 giving jerks on running witch like there is no petrol in the bike/ at the time of Fuel on to reserve.


Three possibilities: You are turning the gas valve the wrong way to get to the reserve position, The reserve fuel intake filter is plugged with some trash or condensation has accumulated in the bottom of the gas tank and ( when on reserve ) the gas valve is feeding water instead of gas. Drain the carb and the gas tank to remove any water. Please rate my answer.

How can I get old fuel out of the reserve tank on '82 Honda Magna 750? I hope to not need to remove tank.


Hi,
Just disconnect the main fuel hose from the carb rail. Ensure that you have switched the fuel **** to reserve and this will allow the reserve tank to empty. Not all the fuel is going to come out unless you blow air into the fuel tank filler, this will then get a large percentage of the fuel out. Hope this helps, let me know how you get on.
