primary pushing out screen

K fixed my last issue and now my primary is pushing fluid out of the vent screen and causing my bike to smell real bad. I changed the screen to a hose like sone suggested but that just allowed it to push all my primary out. What would cause the pressure?

Are you talking about the quick fix BDM did by placing a vent on the outside of the inner primary plate near the starter? I plugged mine with a pipe plug so it would not slobber. Or is the oil coming out the inspection plate on the primary?

The transmission fluid is fine. I mean out of the vent (the quick fix that dBm did). For years the vent was fine but now it is pushing more pull out

Old manual stated 48 oz. that was misprint, they changed it to 32 oz. That is still a lot. I remember from Raywood that you can go as low as 20 oz. That is bit low and only if you have issue of oil getting into the starter...

Not overfilled, I am sure of this because when the screen was on it pushed all the oil out until I could no longer shift

After the fluid leaked out I had to add some, my screen vent was at the house so I put I screw in the end if the tube which I used to replace the vent screen. I think this time I may have put in to much. It is pushing primary out by the drive belt. Even when the primary was low it was pushing all the oil out of the screen and getting on the bike. Now I probably have to much.

If I let some primary out will the leak stop on the drive belt side? Or do I need to fix something now?

A no longer supple rubber crank seal but now dry and blowby has both pressure and engine oil into the primary is one variable. Trans is another, but you said that level was fine.

What is the oil bag level?

Oil looks good

Ok, first off sorry for the poor formed responses. I was trying to play mechanic and enjoy a bike rally at the same time.

I had to take the dog home and ride my honda :(

So the Primary pushed out of the transmission (or at least best I could tell, from the bottom of the drive belt). It would leak considerably more after riding, then stopping and sitting idle with the clutch in (like at a stop light).

I check my engine oil and it looks fine. Not thinned out, not low, and not a bad color.

My transmission fluid was not below the low mark, but more it was NOT an odd color. How can my primary be coming out of my transmission and my tranny fluid not be a new color.

Also,the last primary I put in was a clear fluid and all the fluid coming out is grey.

Anyway, how do I troubleshoot this? Of course as the primary runs low my shifting become difficult, so I cannot ride until I solve it.

Sven means engine oil level.
What do you mean your shifting gets difficult? primary oil has nothing to do with gearbox... If you have too much oil in tranny, then it gets difficult to change gears.
The clutch pushrod goes from belt side to clutch, can the oil transfer thru there, if you are sure the leak is on that side.

oil bag = The remote oil tank. The horseshoe tank. Where you fill the bike up with 3 qts of oil.

1. Engine oil = Gold now black from carbon blowby.
2. Primary oil = Gold in color, will not turn a black color because there is no blowby there.
3. Trans oil = Red like ATF in an automatic transmission. Stays the same color because of no blowby from engine like the...

My oil is what color?
All my oils are leveled off.
Now, who is low and how much is low?
Detail-details-details you want to play mechanic.

How much is the ring gap? Oh, about this wide. I don't think that's the answer. It's more like in 1000ands of inches is the gap. What is the number? Y0ou are playing wit the big boys so be exact in every way or chase your tail I run you around the bike, Simon says, Sit!

Trying

The engine oil looks a little darker than maybe it should be, but nothing that would strike me as odd. at least I did not think until I read this, it is kind of black at this point, not the gold color when fresh. The level is perfect, not low and not over filled.

The tranny oil looks just like it does when it comes out of the bottle. This one is very hard to read because the oil is so clear. It is about half way between the 2 marks, It was full when I changed it last summer.

The primary when leaking out of the drive belt side is definitely grey in color. If I let it come out of the vent it is also grey in color.

After I filled back up the primary fluid cause of the leak through the vent, I plugged the vent up so it would not leak out on the way home. This is what must have forced it out the drive belt side. I should have just towed the bike, but the vent was letting out to much oil and I was afraid I would not make it home.
As the oil in primary leaked out and I was getting close to the house the bike would not shift down gears. Well it would sometimes, but not everytime. I could help it by down shifting as I went down in speed, but not as I came to a stop.

Being a right side drive, the primary fluid should not be near the drive belt. Sounds like you have Primary fluid mixing with transmission oil making one or the other overfilled, thus causing the oil to come out of breather. If leaking on belt, most likely it's transmission oil, not primary. How many actual miles are on the bike? If what I said above is the case, most likely transmission bearings are worn out. Being a 2006, you should write down the transmission numbers and post them here or send me a PM. Most likely you need an entire transmission upgrade with bearings and Main shaft.

I will run a test tonight, but the primary was not leaking out of the drive belt side until I stopped up the vent to prevent it pushing to much oil out of it.

I will see if can get a pic of where the oil is coming out when the vent is stopped up. Since the oil is definitely grey, I doubt it is transmission fluid since my tranny fluid is so clear.

Next I will double check the primary fluid and see how much I have lost. I will refill it and then open the vent back up. At that point I suspect no more fluid will come from the drive side, but be pushed out of the vent.

05Chop, that is the vent I am talking about. The reason I plugged it was because the primary was pushing to much oil out of it and I was running out of primary fluid.

Andrew, I will also get the tranny number, where do I find that number?

Trans problem if now low. Look in the back, under the side, at the top, keep looking at that gearbox for numbers.

the bike would not shift down gears. Well it would sometimes, but not everytime. I could help it by down shifting as I went down in speed, but not as I came to a stop.
Between being gray in color, sounds like something is being chewed up in a fine powder. You have tech01 questioning the trans case number and year so you may need to tear down that primary side, flex the clutch basket up and down and if that is wobbly, send the trans off to bigdog.

Now, there is another problem that may be hidden you do not see. Say the disintegration of the trans flowed thru the push rod and into the primary. Say this brass or whatever metal is being ground into powder, this enters into the rollers of the primary chain. It could eat that support roller bearing so the basket goes up and down, meaning, is the snowball effect taking out part after part. Say the primary cover is off, you swab a finger on the bottom of the outer or inner primary, take a magnifier or a kid's microscope, see if you can tell if it's shinny like metal and looks like metal shavings. That now eats the primary chain inside and this causes a snowball effect of the gray matter. Toss the chain if metal is transferred from trans to primary.

Note the up and down movement of the rollers against the sprocket teeth. If that gray eats into that crush of the rollers, that tooth gap is going to show more wear, become wider; will cause a high spot with a new chain, rather than change it out via 3 parts like a new chain/FF/RR sprockets = 3. So with that much possible wear, the change out is clutch basket-pri chain-compensator sprocket = 3. It all depends on what gray means and if that means metal in my book... :D
