Question about 2005 Suzuki Boulevard S50

1 Answer

On S50 Suzuki Motocycle I have an oil drip from a rubber tube that looks like it comes from up near the air cleaner and exits below the bike. Any ideas before I start taking the seat, tank, etc. off?

    Yes, I inspected the air filter housing and intake and there is no apparent obstruction. I posted some more info for this bike 2007 S50.
    The problem has gotten better as far as volume of oil (just spotty now), but it still concerns me. The first 800 miles or so there was no oil at all. Thanks

The air cleaner(filter) also filters crankcase blowby . Oil accumulates in filter box and drains. The draining is to prevent oil from being drawn into intake an should be addressed by servicing air filter and cleaning out the box. Rapid and excess oil in filter is a n indicator that blowby is considerable. Hardrabbit starts and sudden accelerations play a big part in ring wear and blowby. I've noticed the use of filter sponge placed, not stuffedm in crankcase vent hosebef ore filter housing will separate oil from fumes before they get to airfilter and oil will drain right back into engine instead of collecting in air box. Some crankcase vents are baffled and have a seperation medium factory installed at the enngine end if vent hose. Do not plug the drain or crankcase vent hose. major leaks will sevelope. Over reving will also cause greater oil misting that is carried out the vent with the air. Good luck - note! rapid throttling affects fuel burning eficciency and tends to break down needed cykinder wall lubtication, hastening ring wear. have fun, be safe.

    That didn't explain your problem? Hmmm. I didn't want to say it but make sure your air filter intake is clean and clear. If it can't get enough air it will pull it from the engine vent. Good Luck

    Poke some filter sponge in hole where the engine vent attaches to the air box about an inch in. The material will allow the crank to vent while seperating any oil mist. won't hurt a thing. It will just keep the oil out of the filter box. common practice for a common problem. rots a ruck

John Deere LT 155, why are small amounts of oil dripping into the carburetor air intake thru he oil breather hose connected to that air intake chamber


the breather hose is the means of allowing the compression by pass gasses to not build up pressure in the sump and it exits into the air inlet system near the air cleaner
for oil to be dripping there indicates
1--excessive oil in the sump
2-- worn rings allowing excessive blow by and boiling the sump oil
3-- incorrect oil used in the sump ( too thin) try a 30w -50 grade

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.

Leaking drain tube ac


Is it leaking inside your car? This means that your exit drain pipe is blocked. They are in the engine bay usually near the fire wall and they are commonly a thin rubber hose that drips that water onto the ground. look up underneath and use an air compressor to blow it out or a screw driver to clean it out.

My harley has a small leak coming from the air filter, the mechanic at the harley dealership told me it was the air filter. So i bought a new filter put it on and checked the oil level, with the bike...


Regrettably, a small oil leak from the air cleaner assembly is "normal". This is because the EPA requires all crankcase emissions to be routed to the intake system so that it can be burned in the engine. The result is that oil mist in the crankcase vented condenses in the air cleaner and eventually drips out.

The crankcase vent for your Sporty is in the heads. If you noticed, there are two large bolts that are hollow holding the air filter backing plate on. The crankcase vents into the air cleaner assembly through these two bolts. There is an "unbrella valve" in the rocker box center section that allows the air to flow one way but not the other. There are baffles in this area to keep the oil mist to a minimum but still there is some in the air coming out of the engine.

There are a few kits available on the aftermarket for re-routing this crankcase vent. You can direct the exit anywhere you wish using one of these kits. Most people just route the hose down and exit it under the bike just in front of the rear wheel.

When adding oil to your bike, only add the oil when the engine is hot. On your dipstick, you have two marks. The upper mark represents "FULL HOT" while the lower mark represents 'FULL COLD", Do not overfill. Check the level with the bike on the side stand.

Good Luck

I have a Suzuki gs850 1983. After warming up, I get white smoke or something from the breather tube that exits the top of the head. Moisture in the form of droplets form a small puddle under the bike. ...


Check that your engine oil is clean(not contaminated with water). If you pull the dip stick out with oil on it you could put the oil coated dipstick into an open flame (lighter) for 3-5 seconds if it pops or crackles its wet.if it just smokes a bit its ok. A cold engine will do this fume-steam thing if the humidity is right.Once they warm up it usualy turns nearly clear.Make sure the bike is not exposed to rain, or cold to heat transitions.Some water from the tailpipe is normal,all gas engines can do it.If oil is dry and you dont have water from a cooling system dissapearing,(yours is air cooled) your probably ok.

Using to much oil on long trips 2004 gsx1400 suzuki


That is a lot of oil - is it blowing smoke? Is there any indication of where the oil is going?
The GSX engine is bulletproof - normally - and doesn't use much oil at all. I have serviced 35,000 mile bikes after 7500 miles and the oil has been spot on.
Looking on the net, it seems the 1400 is a bit vulnerable to oil-cooler damage. With an air/oil cooled bike this could be an indication of where the problem lies. The engine won't leak oil while stationary - well, maybe a drop... but when it is warm and under revs any hole in the oil cooler could be a direct exit point for oil. Look for stains on the exhaust headers - if you are driving and there is a leak, that'll be the first place the oil will go.
It would be the first place I would look - as well as oil cooler, pipes, connectors...
Run the bike for a while and try to inspect it to see if there are any leaks you can spot while the engine is running.

Oil overspill coming out of air cleaner/filter


Relax...... Harley's all vent oil thru the air cleaner, actually, S & S does to, except they put a overflow valve so it drips on the road rather than the engine. Various little things can cause the oil flow to increase, and yes, over filling, over heating, and sometime, just running balls out for awhile.

Its normal, and shouldnt cause any problems more serious than oil mist on yer engine ( and sometimes passenger)

Check the compression. Pressure getting past the rings can cause the problem. Does the bike burn any oil when you ride? If it does the rings are suspect....... Okay, you have oil > is it the right oil? The prior owner may have put something stupid like 5w30 oil in the crankcase. Do an oil change and put in the heaviest oil Suzuki says is proper. If extra emission stuff is on the engine the dealer should be able to identify the items and you or they could remove or bypass them. Are they contributing to the problem... who knows. Kind of a shot in the dark on that part of the equation.

2006 Suzuki DRZ400S oil leak from bottom of air cleaner.


Often times there is a engine breather tube that has to do with emissions that runs from the engine to the air filter breather box. This tube can in some cases blow oil through it when the engine is run hard. Make sure you're not over filling the engine with oil when you change it because this will cause the oil to "blow off" the excess and the air box is where it often goes.
There is also another possibility, are you using too much oil in your air filter after you clean it? This too is a common cause for oil in the air box, if that's the case I would not worry about it.
The last case scenario is one you don't want, that would be washed out rings which cause blow by and that in turn causes the engine to blow oil out of the breather tube which I'm confident it venting into the air box.
Please let me know if these resolve your question and if not give me more details and I will be happy to assist you further.
Regards,
RSelvy
