Hi Michael the problem with many older motorcycles is usually gas working its way from the fuel tank and dirty or worn carbs into the engine check your oil level and to see if it is overfull and smell it for fuel. Change the oil and refill to the proper level then you need to check your fuel system.
1. check to see if your fuel petcock is not flowing and the setting is on on or reserve. If it is still flowing then the vacuum diaphram needs replacing.
Position PRI is for when you run out of fuel and needed to prime refill the carbs to get the bike running then turn to reserve. hope i Explaned it clearly enough hope this helps.

check the oil level again. trace the tube to see what it really is. make sure it isnt coming from the oil filter. had 1 that was the wrong size and was like 2mm off in length. screwed down tight but had a persistent leak. good luck. if it is the oil overflow, I used a very clean shop towel and wicked out excess by dipping it in the filler hole.

The float is stuck open giving the carb fuel constantly. The extra fuel runs into the intake, fills the cylinder, gets past the piston rings and then fills the gearbox and overflows onto the floor. Pull the carb and clean it. Some trash, ( such as rust from the tank ), is not letting the float needle to seat. Also, turn off the gas at the tank when you are not riding. If you already are doing this, the petcock must not be shutting off properly and needs to be replaced. Right now, change the oil in the gearbox. Please rate my answer. Thanks.

You will likely need to remove, disassemble, and soak the carburetors in carb cleaner.
Although drained of fluids, there's almost always some left over gas and it turns to shellack over years, and will cause things like the float valves to stick.
You can try just spraying carb cleaner into the carbs and hoping it works, but dis-assembly will likely be necessary.

SOURCE: oil coming from transmission overflow

It sounds like the transmission is overfilled. Check the level of the lube by removing the plug from the chrome end cover on the right side of the bike. It usually takes a large hex key to remove the plug. With the bike standing straight up, the level should be between the two marks on the dipstick. The transmission holds between 20-24 ounces of oil.

Good Luck
Steve

Oil running through carbs


Hi, Kyle you have a lot going on here that needs professional attention plus it's an old bike you probably have contaminated carburetors that need a "Chemical Dip" as for excessive oil in the air box that could be from too much oil in the system for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry. If necessary, transport your bike to the dealer or shop and have a professional technician take it for a test drive, if it is in running condition, and give you a written estimate of repairs and answer any specific questions you may have about your problem.

I just bought a 03 honda 450 and oil comes out of a tube under the motor when started...why is this?Also how do you check engine oil and transmission oil?


Is this a CRF450 single-cylinder off-road bike? If so:

If it's coming out an overflow, it may be overfull. Not sure on that--haven't seen it before.

To check engine/trans, drain, refill with (670cc w/o filter change; 690cc with filter change), start engine, shut off engine, check sight glass on side of engine. If it's low, add oil and repeat start/shutoff/sight glass routine until it's full. Engine and trans share oil.

If it's still pumping oil out the overflow after you're sure it has the correct amount in it, be sure it's oil and not coolant, battery acid, or gasoline (there is a gas overflow tube on the carb for when the float sticks).

1996 suzuki bandit 600, I start it up, and after about 30 seconds gas starts leaking from a tube that comes out of the head and goes into the top of the airfilter box.


Fuel mix is escaping either due to the oil level being too high, usually when diluted with fuel from an overflowing carburettor Or if the engine pours out white smoke at the same time, it may be due to duff rings ie the crankcases are being pressurised by gases getting past the rings on compression stroke

clutch pushrod should just pull out as it should be a 2 piece clutch pushrod model, earlier models were 1 piece and you had to remove clutch cover and pressure plate to remove. hopefully the seal is ok.

It should build up some pressure, before it overflows as it heats up, perhaps you need a new cap.
If the bike starts and runs ok it probably isnt a head gasket gone

Why is my motorcycle leaking oil from the overflow tube? I let some oil out to be sure there wasn't too much oil, but it is still leaking. It leaks when it is off on its kick stand and it leaks when I...


You have a crankcase breather hose that may be blocked, allowing excessive oil pressure to push oil out. It should be routed to the airbox. This may also be the overflow hose you are speaking about. Your oil type may not be suited to a motorcycle engine, automotive oils are NOT suitable for bike engines for many reasons, notably shared gearbox and engine oil and a wet clutch. Check function of the oil pressure switch as this should send a signal of loss or excessive oil pressure. Check your manual for correct weight and quantity and type of oil filter needed. The oil level is indicated on the stem of the oil filler cap.
Cheers.

The overflow tube coming out behind the swingarm? If that is where it is coming from sounds like your float in one of the carbs could be stuck.
