pete_4854,

I failed to see the throttle body support bracket! Thanks for the info!

Here's the picture of the upper TB cross brace.  It bolts under the banjo bolts and then has two bolts down from the top into the top of the throttle body.

Also Robertg, if everyone is so concerned about the oil debris inside the AC, what happens when the condensed oil and water vapor hits the filter and then drains down the side of your transmission?  Just thought that was an odd place to put the filter.

I have my old Shovelhead crankcase vented out the back and under the frame at the rear of the transmission.  This is out of sight and only a little vapor comes out.  UNLESS I've let it set of a month or so and the crank sump fills up and then it's a HUGE mess when it's fired back up.  Be prepared to clean up half a quart or more.

Can't speak for a shovel head, but not the case for a twin cam.

Evo motors will sump up.

I agree on the Twin Cam as it has a pan that's lower than the crankcase.  It will not fill up with oil.

My point was to hide the filter underneath rather than possibly oil filming the side of the bike over the long term. 

[SneakyPete]

If he were run the hose the way I did it, there would be no need for a filter at all and there would be no hose visible, nor any oil venting to ground.

The key point is that you route the hose up, not down and let gravity return any oil back to the head.  No oil will get past the banjo fitting before it runs back into the head. It is the same concept as using an expansion tank for a hydraulic system.

Old thread I know!

Anyway to do this on an 2007 FLHTCUSE2 bike regarding the throttle body support bracket?  I don't have holes in my HPI 58 Max-flow to marry up to that bracket shown in the photos.

After 50 years of fooling with motors, I see no need for this diverting the overflow waste. Let it burn, combustion temp is so high these days that immediately the fumes are turned into exhaust waste go away and they are almost fully fumes at this stage, turn to liquid as they cool and accumulate in hose or can. If really worried about it, use a add-on bung welded into high vacuum area of exhaust and let the exhaust suck it out like we did our race cars 40 years ago before we found vacuum pumps. But nothing I want to deal with in a can hung under a vehicle. JMHO.

My experience as well! Good post.

I have the old cable throttle body.  Is there a support bracket that might work as shown in this article?

Thanks!

Sorry guy, I don't know anything about your intake plumbing.

On mine, the bolts holding the intake to the side of the motor are hollow and allow the gasses in the valve rocker arm area to vent into the air cleaner area.  By drilling and tapping, and installing a fitting, I routed those gasses to the ground. I plugged the orifices in my air cleaner backing plate with Blue RTV.

The reason I did it was not to prevent those gasses from entering my cumbustion chamber, but to prevent the condensate (mostly oil) from running down the inside of my air cleaner, saturating the air cleaner element, and ultimately dripping onto my cam chest while parked, or accumulating and then blowing all along the right side of my bike at speed.

Not everyone has this problem, nor chooses to fix it they way I did.

You did a great fix!  I just found what I was looking for so I could use your design to complete mine.  I was simply looking for a support plate that could support my throttle body.  Your support plate bolts to your heads and the top of your throttle body and mine does not have those holes on top of the TB so I need support from the face of the throttle body.

Just in case anyone else would like to see here is a photo of what I found online.

Thanks!!

Similar to Dan's set up, DId the banjo fitting s from Kury,  milled the backplate the thickness of the fitting, bolted it right between backplate and head. Hoses run up and well hidden, no catch can, haven't seen a drop on the ground yet. Oil is running uphill.

The "final" leg of the breather hose is actually in contact with the top of the rocker box before it goes through the hole in the frame & then on down to the ground.  I cannot route the hose so that it is not laying on the rocker box.  I am concerned that the heat from the rocker box will melt the hose.  Anyone have a problem with the hose melting?

[r0de_runr]

Nope.  I used 600 degree silicone fuel line.

[jimfreeman]

Good to know.  Thank you.

I used standard Advance Auto parts 3/8" fuel line.  No problem, but which hole in the frame?  Right or left side?
