Crankcase snerk - 7/6/2008 10:20:42 PM

Just wanted to post a pic of how I snerked the crankcase vent. After a few beers I decided it would be best in the airbox. After flippin it at Nats and filing it up with water, I decided to change the vent and put in the filter. I figure if water gets in the airbox, the airfilter will filter most of the grit going to the throttle body and the breather filter will do the same for the crank. Just seems better to me that putting it on the pod. Then you have to cover it everytime you wash your bike, etc......I also used clear hose to see what is happening.

me to^ this way looks just as good tho if not better.
Micah needs to see this! he was wondering how to do his where water couldnt splash up in it so this would be a good way. plus you dont have to plug that hole. i like this way

only negative i see is you are in the same place as stock. just with a filter. much better to get it out of the air box.

It won't get wet unless a catastrophy occurs and it is only insurance that no sand, grit, mud, or any debris will enter the crank. Stays completely dry unless water goes in the airbox snerk, and if that happens then zip tied under the pod isn't going to help either. You have more chances to get it wet everywhere on the bike except for the airbox.

The vent tube sucks air in correct? It doesnt blow air out right?

its goes both ways, in just does which ever it needs to to vent the crank case so it has no pressure in it.

I actually think he has it pretty good. If you seal up the lid and make it tight it should be good. LIke he said if you flip it, its gonna fill up no matter what. Inorder for the gunk to get in it inside the box, it has to be swamped. But keeping it inside there keeps normal water and mud out even from a tilt or a short swamping.

with the small filter and a loop in the hose it will not suck in water. canams have so much compression even stock that it blows out 99% of the time. using the staimless steel filter i have rolled mine the way i have them mounted on the pod and kept the crankcase water free. upside down it wont let water in. with it in the air box and you fill it with water and your bike dies. then the pressure of water will let it in and down to the cranicase before you can get the airbox drained with your bike upright. that is why we run them on the outside of the airbox.

i ran about 5' of hose on mine and wrapped it around the air box in a big loop so if it goes over and fills up the air box the water should not ever get to the crank case from the loops in the hose. also did my top carb vent and gas tank vent the same way. only water getting in my quad is threw the valves ..

I think running a couple loops in these things is the best way to go wether its in the air box or not.

Think of it like this, your bike goes under water....belly up, belly down, or whatever. The hot motor which has expanded the oil thermally is rapidly cooled causing contraction therefore sucking in air. Now imagine splashing into a pit or waterhole and splashing water underneath a zip tied under pod or pod mounted filter.....I am eliminating that water entering the crankcase vent.

hit a pit hard on entry and you are going to fill your airbox full of mud and water. happens every time. especially in a mudda cross. going to have to clean the box every race.

the loops are a must, garrett with every bike. the crankcase vent is the saest way to keep crap out of crank.

Well, it's got clear hose on it so I will be able to tell if crap is going in. Should also be a good indicator of any foreign liquid in the airbox. You can't see in the picture, but I purposley used enough hose to put a loop in it remembering your theory of it not allowing water in upside down.

i agree with biggbowls. the only way you can get water in a snorkel'd crank vent with a filter is to flip it. but you have a better chance of ''splashing'' water up into the bottom of the pod from washing or whatever than you do getting any into air box. and if your snorkels are higher than your pod and you go that deep you'd need it like this imo

Let me see if I can explain my reasoning behind putting the vent behind the speedometer. Just an example. We did this mod to a buddy of min'e 650 about 2 weeks ago. Well last night the bike tipped over sideways far enough that the intake snorkel went under. The crank vent did go under for a split second along with the intake. Thi split second was enough to fill the airbox completely up with water. What would have happened if he had the crank vent in the airbox? Water would have to continued to drain into the motor until the bike was pulled out and then stood on it's rack to drain the water out of the airbox. That motor would have been FILLED with water if the vent had not been out of the airbox. I have competed in several races with mine done the same way and there is barely any "splash" residue on it. After the races I checked inside my airbox and it is covered in red mud, especially the spot where the crank vent would have been, filter or no filter.

I'm not trying to down the original poster's idea, but I believe there are better places to put it. All my group does is ride in deep water and 3/4 of us have the crank vent pulled out of the airbox with a filter on the end. Out of the many times the ones that are set up that way have filled their airboxes up with water I have only seen water in the oil a couple of times. That was because they were upside down in the water for everal minutes. Now the ones that left the vent alone ALWAYS milk their bike if the airbox gets any inside it, thus ending their ride for the day.

SDF......look at the third picture. Notice the valve stem......it has no guts. It will drain that airbox in about 15 seconds. There is no standing the bike up on it's rack to drain it.

OK Eric, here it is. Thanks for the parts today. You are right and I am wrong. The airbox is the worst place in the world to put the crankcase vent.

Unless you want to keep it dry

Had to do it!!

is the crankcase vent the same on all bikes, on my carbed big bear it was originally tied into the intake tube going to the airbox, when i snorkeled i had to put it another place and i wanna say during mud nats i had the to put a fitting and a long tube and ran it up my snorkel which was fine no big deal, but it came off the left side of my motor and all my snorkel and vent lines came off the left also, when i made the vent line bend around back forward it made a nice semi halfway crinkle in the vent line, the entire nationals while running i ended up having to pull the vent line off the fitting and drain the water out of the vent line

not sure if its the same with yall or what, the longer the vent line the harder itll be to keep it dry from the steam and heat....like i said im not saying much or actually saying im rite and none of yall are cuz yall are into these things way more than i am, but after mud nats i drilled a hole in my airbox and put the hose into there and siliconed it up, i have since then not had any residue in the line, it traveled like 8" when it was stock, then it was running like 3 or 4' when i first ran the line for mud nats, then after i ran it into the airbox its like 12" long so not far to travel at all

but im sure yalls have alot more pressure going through them so it doesnt really matter the length of it at all

anyways to all his own, run it the way yall want it run and let her rip

i took some pics of my air box today from the race in nacogdoches. what john is referrign to is that i had about 1" of mud and dirt. and another inch of water still in there from just five passes through the pit. the intake snorkel suck so hard that it is going to fill up the airbox if you hit the water hard enough. so having it in there is just going to lead to having to clean the airbox and crankcase vent everytime you ride or race.

Eric, that is true. Your airbox was proof that it is not the cleanest place, but in all honesty, the only reason I put mine in the airbox is to keep the filter dry when I wash my bike. Believe it or not, I am already giving consideration to changing my airbox snerk to the same as yours. I might end up coming by to get that airbox you have for sale.

I think its a great idea to put it up high in the airbox. The only bad thing is the mud races (especially the muddacross) because there is so much extra water/mud splashed on the outside of the bike from other riders that the intake sucks alot of crap into the air box. Usually from entering with bikes next to you. For racing, behind the speedo is best because there is actually less mud/water under there than in the air box when you are done.

Always put a loop in the hose no matter where you route the filter because that can save you. If you think there may have been water around the filter just pull the hose and clean it out. The loop catches a lot of secondary contaminants.

biggbowls, the installation is clean! Great job!
