And with the V50 I thought I'd achieved my ambition. It was oiltight to begin with but not long after I'd done a bit of maintenance (oil and air filter change) I started noticing drips underneath - coming from the pipe that dangles from the air filter unit (yes it still has the original [expletive-deleted] item). For a while I ignored it as there were so many other jobs needing to be sorted, but it has just got worse. After a long trip, parking it is embarrassing - especially as everyone knows that Guzzis are oiltight . . . Now it seems to me that the oil could have come from one of three places - the crankcase, or either of the rocker boxes, as all of their breather pipes go to the underside of the air filter chamber. I therefore detached the existing pipes to the rockerboxes, stopped up their ends, and ran new breather pipes from the rockerboxes to vent under the bike. I reckoned that, with three pipes dangling underneath (Sherlock Holmes' three-pipe problem?), I should be able to see which part of the machine was responsible. With me so far? Did a 21-mile trip this morning, put it back up on its stand and waited. Result - oil drips from all three pipes! Thinks: when bought, the oil level was only just above minimum on the dipstick. When I changed the oil, I filled it to the max level - and someone has suggested that this is the cause of the problem. I therefore drained some oil out, and it's now at the half-way mark though without any effect on the oil drips. I'm reluctant to drain more, though that might be the next step. If it does effect a cure, would that point to some other, underlying problem? Any ideas or suggestions welcome, as at the moment this machine is not living up to the Guzzi reputation.,The breather system on the V50 works in a peculiar way. The two pipes from the rocker covers are the main engine breathers. They go into a chamber in the air filter housing, and the tube from there to the crankcase is actually a return pipe, to get the oil recovered from the breather back into the sump. On mine, I am sure the breather then goes into the air box behind the carbs, and I didn't think I had another pipe dangling down. Certainly too much oil in the sump can cause problems in most Guzzis.,,,

Why is differential 90 weight gear oil leaking out by the bottom of foot shifter in that area you can see it leaking on ground and in starter the gear oil for a drive shaft bike not a water cooled bik


After riding the bike the oil warms and thins so finds it easier to find its easy out.
It sounds like you have a leaking seal that needs replacing.
Found out exactely which seal is leaking by wiping all oil off the bike and getting down and watching where it comes from it will start with a drip then go from there

hi what you have just described is the head gasket leaking.you say you do not get a drip on the floor??check to see if the oil has travelled towards the rear of the head??if so how much??although this will not really affect the bike under normal riding it is recommended that you get it repaired sooner rather then later.

I just noticed a slow leak on my 2003 deuce. What is the best way to deal with it?


Well, the first thing to do is to figure out where the leak is coming from. This is sometimes not as easily done as it sound. The wind while riding has a tendency to blow the oil back, up, and over and makes it look like the leak is coming from somewhere that it's not.

So, clean your bike completely even if it means using a pressure washer. Do not hold the pressure washer nozzle to closely to any part of the bike. If you hold it too closely to the steering head or the center of the hubs, you could force water into the bearings. I've taken transmissions apart and found water in them after they'd been pressure washed. So. just enough to make sure you get all the oil off your bike. Then, park the bike on a large piece of cardboard. Let it sit and watch where the oil drips onto the cardboard. The oil will drip straight down. This doesn't mean it went straight down to get to the drip point however. Once you fnd out where the oil is coming from, knowing how to fix it isn't a problem.

Good luck

I had a oil change done and the next day I had a leak...comin from a seal and my bike never leaked...the mechanic thought the bike took alot of oil so could he of over filled and cause pressure on the...


Well if overfilled, that does not make any sense, can you check the level? Once a seal starts to leak, it will continue, so investigate the leak and fix it. It will only get worse.

Small amount of oil on the bottom of crank case on the kickstand side! its not pouring but does run down the kickstand! bike only has 10k miles


The oil could be coming from anywhere. Just because this is where you see the oil doesn't mean that it's coming from there. When riding, the wind blows the oil around and sometimes you see it well away from where it's leaking.

You need to wash the bike paying particular attention to cleaning all the oil off the engine. Then, take the bike for a short ride of about ten miles or so. Check the plugs where the crankshaft position sensor and the voltage regulator plug into the case. Also, there is a large O-ring between the engine and the inner primary case. This could be leaking. For that matter, the cam chest cover could be leaking and running all the way across the bottom of the engine and dripping off.

A method we used to use was after washing the bike thoroughly and taking the bike for a short ride, we would powder the suspected area with foot powder or talcum powder. Blow off the excess but the oil would hold onto the powder giving it's source away.

Good Luck

Leaks oil from underneath somewhere but only when hot.


The only way to find the leak is to thoroughly clean the engine and then ride the bike for a short distance. Then park the bike with a large sheet of cardboard under it. Watch for the drip and look straight up. When riding the bike, the wind blows the oil all around under the engine.

Good Luck

Oil leaks


Hi,

Don't worry. The bike builds up a little oil at a time.
This is 2 stroke oil that is unburnt during combustion.
You might be running the bike a little rich.
A mix of 32/36 to one is good for outriding.

You should de-carbon the exhaust and replace the silencer packing. This will also give you some unexpected horse power.

Enjoy the ride !
