Ok guys here's the problem bike was running ruf so i took carbs off and cleaned them problem is I'm having trouble putting hoses back in place. on the front carb there is a spout thats next to the air intake. does that connect to anything? on the rear their is a spout next to the fuel line. where does that go? I'm told that this one is an overflow and the first one is a vent. I've looked on line for some pictures but no luck yet.

When pull the choke on my cv carb the bike runs great when i push it in runs like **** can you help


Sounds like the bike has been sitting for awhile or trash has gotten in the carb and the slow speed jet is plugged up. This means that not enough fuel is getting to the engine. You need to remove the carb from the bike and go through it completely.

This is not a job I recommend for an amateur mechanic on the original Keihen CV carb. There are several areas where you can get into trouble when reassembling the carb.

Now, if you disconnect the fuel hose, the throttle and idle cable and the choke cable at the knob end, you can take the carb to a qualified mechanic, have it cleaned, and then reinstall it.

Good Luck

Starting trouble


If the odd substance was at the bottom of the float bowl it was water. If it were oil it would have mixed with the gas and you would not have seen it. Drain the carb into a cup to remove any additional water from the carb and petrol tank. When no more water comes from the tank you should be okay to start the bike. Clean air filter? Water gets into the tank via condensation in the tank.

1986 Suzuki Savage loosing acceleration


I have been having a simular problem with my girlfriends bike.She complained about the bike looseing power or "bucking " as she calls it , at speed.Several "shops" have played around with it ,but none have solved the problem .She feels the bike is not worth spending any more money on ,so I have tackled it .
The first thing I found was that someone had put the wrong hose on the pet ****. To open the pet **** you need vaccum from the cylinder side of the carb. There are two other hose nipples on the filter side of the carb that I don't know where they go .If you know , please tell me .The vaccum helped but didn't solve the problem.So I took the carb apart , cleaned out all the jets . One was pluged.
Now I have to run the bike a little,then check the spark plug. I think I am getting close.

Gas pours out of bike when I turn the key


Sounds like one really crappy and dumb dealer if you ask me. Yes, they usually have gas in the tank on the showroom floor. Yes, varnish can build up while on the floor. The good thing is that cleaning a carb is not very hard.

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. Install a new stock NGK spark plug and try to start the engine. 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!

My DR 800S 1991 IS LOSING POWER


you say theres petrol running from the hose from the airbox? if so that aint right and sounds like your carburettor floats are sticking open which would flood the bike and make it run rough and to rich sometimes bashing the float bowl on the bottom of the carb whilst still on the bike can free a sticky float use a bit of 2x2 or 2x4 and jab it dont use a sledge hammer or something lol if that dont work strip down the float chamber and clean and try again all the best
