I have just fired my bike up 1200 bandit and there is a lot of white smoke coming from the exhaust i thought it would burn off but it keeps doing it and cutting out


Ok I have one of these.They are not water cooled so it's not steam from a leaky head gasket,it would by be oil unless it's bluey coloured smoke.if it was too rich ie choke stuck on or blocked air filter you would have black smoke.so I would say it's one of two things.you have either put some diesel in it as that smokes grey and fouls the plugs making it misfire and cut out or the small drain hole in the left hand side of the fuel filler cap well has blocked up and you do have water in the fuel.drain the carbs via the drain screws on the bottom of the float bowls and catch it in something,if there is water in it it looks like jelly in the petrol.Ok good luck ps that's a man's bike.;0)

I have a 2007 Honda Dylan 125. It was working fine then all of a sudden wouldn't rev up. It starts and idles but as you twist the throttle the engine dies.


Check throttle cable. It may be broke inside the casing. If that's okay it could be a stuck carb float or plugged jets. I hope this helps there are a lot of possibilities.

Gas is runnung out the over flow tube and bike wont start


Either something is stuck in the float bowl valve or similar. You will need to shut off of the gas, drop the float bowl, check that the float move and closes the valve. If everything looks good and the valve actually closes, then there is a chance the float is fuel logged, or soaked with fuel. It won't float then. Replace the float, clean and/or replace the valve, clean the seat and check for scoring. New gasket on the float bowl, tighten it up, and you should be set.

Hi I own a Transalp that I bought in UK . a couple of years ago I emmigrated to South Africa and took the bike there. However over the last year and a half I have been working in Asia and the bike has been...


hi, first thing you should do would be, to remove the fuel from the exhaust, you may have to remove it to do this, it must be that while the bike was standing the fuel has leaked from the tank, through a sticking float valve, into the engine through the inlet valve which must have been open at the time, and filled the cylinder with fuel, when your friend has attempted to start the bike the fuel has been blown into the exhaust, and lay here untill the bike fired and run, this is most common on two stroke engines, normaly a four stroke in this position would hydrallic,

the fuel will eventualy clear as the bike is running,

your best bet would be to remove the float bowl from the carburettor, and check the opperation of the fuel cut off valve, this may have become contaminated by old fuel which forms a varnish type substance when allowed to stand,
the cut off valve is located under the float which you will carefully remove, place a clean cloth or similar under the carb where you are working, if any parts fall onto the paper, you will quickly find them, i hope this advice is clear and meaning full, if you require any further help , feel free to contact me , paul

Replaced head gasket bike runs on tickover smokes a lot and seems to b burning the engine oil and will not rev


Try a thorough carburetor cleaning. If the carburetors are not set correctly, are dirty, and feeding an overly rich fuel mixture (malfunctioning choke, or stuck open float needles) this can cause smoking and poor acceleration. If oil and anti freeze got into the exhaust during the rebuild that could also be a source of some of the smoke . Only a long drive will take care of that.

When I crank the engine on my 1997 Suzuki LS650 Savage it starts leaking fuel out of the middle of the exhaust pipe at the junction of the muffler and the header. No start, plenty of fuel leaking out...


I suspect the float in the carb had stuck down.
Strip the carb down and replace any corroded jets and fuel float valve.
Change all fluids, oil etc. as you need fresh lubrication to keep the engine going smoothly.

Fuel leak on a 1992 Kawasaki En500


The hose does not need to be connected anywhere. It could be a battery, crankcase or carb vent hose. It is fine as is. The problem is a stuck carb float or a carb float out of adjustment. Unfamiliar with BMW, I assume you have carbs and not fuel injection. Remove and clean the offending carb.
