Breather Tank Install

Decided to install a breather tank on my dad's 09 Triglide so the engine didn't have to ingest that nasty sludge that comes out of the breathers. Over time venting the rocker boxes into the throttle body to be burned will carbon up the piston top which after time could cause a rise in compression and pinging.

This is the piston of my 06 Ultra when it was a mild 95" build and venting the rocker boxes into the throttle body, this piston only has 8,000 miles on it.

This is my 06 Ultra with a different 95" build which used a 10.1 piston and rocker boxes vented externally, this piston has 27,000 miles on it.

The modification I did was fit external vent lines to the stage 1 Screamin Eagle air filter backing plate, the same could be done with any backing plate that vents into the rocker boxes like this one does. Since the trike has a lot of air moving around I choose to use a breather tank vs venting to the ground, venting to the ground would have coated the under side of the trike pretty badly with an oily residue due to all the air movement.

I chose the 1 pint Jaz PN 605-325-01 mini breather tank with .25 fittings, I bought most everything from Amazon. This is the tank http://www.amazon.com/gp/product/B002RL3E62/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1

I installed the tank on the left side down tube and oriented it so the vent door on the fairing lower could be closed, I used some rubber strips to keep from marking the finish on the down tube.

I used Russell PN 660423 http://www.amazon.com/gp/product/B002Q3EQCC/ref=oh_details_o08_s01_i01?ie=UTF8&psc=1 which are 1/8" pipe to -4 an. If you have throttle by wire you need to make sure you place the fitting so it or the hose does not hit. You need to drill and tap the hole for the 1/8" pipe thread in the cavity where the breather port enters. Locate one fitting for the rear cylinder and one for the front.

I used Russell PN 632013 6' long -4 an proclassic hose which was enough to route the lines where I needed http://www.amazon.com/gp/product/B002Q3ERBC/ref=oh_details_o08_s02_i00?ie=UTF8&psc=1 . I also used 2 Russell PN 610013 -4 an straight hose fittings http://www.amazon.com/gp/product/B002Q3AZMM/ref=oh_details_o08_s01_i00?ie=UTF8&psc=1.

You will have to plug the ports that where used to vent the rocker boxes in to the throttle body, I just used some Ultra Copper silicon and stuffed it in to the port and smoothed it over. I didn't want to drill, tap and install a set screw because its a good way to have something come loose and be ingested into the engine to do damage.

I picked up a couple rubber lined clamps to run the line from the rear cylinder through, I used the lifter block bolt to hold them in place.
In this picture you will notice some covering over top of the braided hose which is held with zip ties. This covering is to protect the braided hose from the hot exhaust pipe. The covering is Heatshield products PN 204002 heat shield sleeve which is rated for continuous 1,100 degree exposure and 2,000 degrees intermittent, one package was enough to do both lines http://www.amazon.com/gp/product/B004GNLGTQ/ref=oh_details_o08_s00_i00?ie=UTF8&psc=1.

This is a shot of the hose from the rear cylinder to the right side of the breather tank, you can also see the hose from the front cylinder to the left side of the breather tank.

This is the breather tank with a rain sock over top of the filter to protect it from rain. It comes from Outterwears.com PN 10-1132 http://outerwears.com/proddetail.asp?prod=362.

This is the completed right side of the engine with the air cleaner cover installed.

Ok Mike when ya going to do mine so I don't carbon mine up after spending so much on this rebuild? Please! Jim P.S. What a difference.
 
Mike, good looking installation!! I did the very same idea on my 120r when it was in my 2008 Ultra (since re-installed in my 2013 TriGlide) with the SE Ventilator Performance A/C. I have since changed my A/C in the Trike to the SE Heavy Breather and am currently back to the venting into my TB, which I don't much like.

I still have the Ventilator backing plate with the drilling/tapping to prevent the venting to the TB and the fitting that route the hose to a catch can that I had mounted on the front left down tube. I used the same catch can that you show and the thing worked perfectly. I haven't figured out a way to modify the backing plate for the Heavy Breather so I can re-install this system on the Trike. However, I am still looking to re-install in the future if I can come up with a good way to modify the Heavy Breather backing plate.

Oh, by the way, I still have the SE Ventilator backing plate (all drilled/tapped with hose fittings), hoses and the catch can that I am not using if you know anyone that needs that step completed for the SE Ventilator A/C.

I really like your application of the SS hoses!!

Take care;

Roger
 
OR... You could just add 2oz Marvel Mystery Oil to every other fill up and get the same results.:laugh:

I'll bet your handy enough you could do the same thing easily, its a pretty easy job if a person has some mechanical skills.

I haven't worked with the Heavy Breather but it looks like they use the hollow bolts with nipples on them which hoses used to fit on to, except it has ports in the one ring to direct the vented crud. On the old stage 1 setups you could drill the hollow bolts and plug the ends then drill and tap the body of the backing plate to accept the fittings for external venting, you just have to make sure you get the hole within the chamber the hole through the hollow bolt is in.

On my 06 Ultra I use a Doherty power pacc with their vents, I used -6 an hose and vented to the ground under the bike.

I vented my heads basically the same way. I used the longer breather screws you can purchase from Kuryakyn.
My vent lines are behind the air cleaner cover tee under the TB. I ran a hose through the cylinders then down to the catch can in a lower location on the same side as Mikes.
 
I have used one like this in the past.. Mike is pretty handy with his setup.

The catch can I used had connections at the catch can for each individual hose from each cylinder, and a petcock at the bottom for ease of draining the contents, as well as a filter element at the top. I found the petcock to be very handy!!

The only breather I've installed was on my 88 softail custom. But that only had one hose going to the carb. Does this effect the EFI or tuning?

This has a drain on the bottom also. This one I believe uses a hose splitter to connect a 2 into 1 hose .

It doesn't affect the tuning, depending on hose size it can cause the engine no to vent properly. For awhile I ran 3/8" hoses tee'd and going to a single to the ground on my 06 when it was 95", never had any problems with that setup. I went to 2 vent hoses on the 120 to make sure it would vent properly, and decided to do the same thing with my dads. The Jaz breather tank is a pretty decent value at $64.27 from Amazon, some of the other cans are pretty darn pricey.

Your correct you have to tee the hoses down into a single hose on that can, its a nice looking piece and if I remember right their around $135+.
 
Thanks Mike, sure like how clean the top of that piston looked.

I was surprised at how clean it was also. The only piston I've seen cleaner was in the blown BBC from my brothers dragster which ran methanol. The pistons in that looked almost like the day they were installed, pulled the engine down every 65 passes to replace the bearings and connecting rods. Never had to clean anything from the piston tops because they were always clean.
