Sounds like your engine may have gotten so hot that it compromised the filters in the breather bolts. You should have received an extra pair with them, I would try replacing the ones in there. If can't find them, just email or call and we'll send you a few extra.

You can do some things to cool the bike down for the next time you get caught like that, then you won't have that problem again. Or, if you prefer, you can just change to a system like the Discrete Head Breather or the Premium Discrete. Then no matter how hot you run you won't have anything like that happen again.

Both good options, but with a raw hose and no filter on the end, these guys running so hot will end up dripping oil on the garage floor, or wherever the bike decides to marks its' spot.

IMO it's best to take steps to use the HD Corporate recommended viscosity oil for the temps being ridden in. (NOT what most dealers recommend) And to take steps to cool down the bike...it is possible to do, even in stop and go traffic.

 

Here ya go. Will also work on Ness and others. Just make sure the fittings are flush or lower so oil will drain. Had to do a little filing on one.

 

How do you make sure the fitting are flush, and still tight?

Thanks

 

Use teflon tape on the threads and they will hold in place and not leak. The nipples will have a flat surface that is butting up against a round surface, so it is not going to be flush except at the apex.

The teflon tape (like used for plumbing) will act as both a thread-locker and will seal to prevent any oil traveling down the threads and dripping.

Decades ago, when the EPA first mandated recirculating the hot oily air into the intake, this is how many of us got around it.

Now there are more aesthetically pleasing ways (and less labor intensive ways) to do the same thing, like the Outlaw Breather Bolts and the Premium Discrete Breather System, there are also some very fancy catch can systems, but the method pictured by Oldhippie will work just as well.

 

Screw them in and use a round file if they stick up.

 

The Premium Discrete Head Breather System now comes with the High Temp Black T AND a Brass T, so you can use whichever one matches your bike the best.

 

When I had a DK customs outlaw on my bike I made my own kit after trying the aluminum breather bolts with filters which here in Vegas in the summer means top end engine smoke drifting right back in your face at a stop light in 115 degree weather.

Brass t connectors are cheap at Home Depot, Lowes, Ace, and pretty much any hardware store that carriers brass plumbing parts. The auto parts stores all carry various types of hose for fuel, vacuum, etc so was pretty cheap to make one and you can find the little chrome cap filters there as well. Discrete oil breathers can be made for about $20
