I tried the plastic bag test that Ron speak’s of and got no air in the bag. Because of this and no oil in the filter I didn’t see any need. The other benefit of this mode that you are referring too was the main reason for the reverse in my decision.

 

today I took advantage of the rain to mount the big leather saddlebag I had on the Heritage at the start...
I like it, it gives it a bit of an adventurer look, and now at least I can take things with me, go shopping. I've always liked having at least one saddlebag on my bikes, it's very practical...
I think it's a bit low and too far back, so I'll probably change its position...

 

trask is on!!!

 

I'm going to reroute my vent hoses to the outside of the air filter first, as I did on the Heritage because since I've done it, my filter stays clean and that's what matters to me...
but after all, maybe the Trask is a plus too ?

 

the trask is supposed to eliminate or reduce oil from the head breather’s. Some do the external and trask. Some say doing the external breather takes away needed vacuum. I don’t know. I get very little oil from my head breather’s. The trask is a very nice piece, I now have replaced the 3 plastic parts that should not be on a Harley Davidson motorcycle. The plastic intake manifold, the tappet cuffs and the plastic trans cover. Not saying they are problematic they are just ****.

 

I agree about what you say about plastic parts, I didn't know about the tappet cuffs...
I'll probably change the gearbox cover in a while, but for now I've got other priorities to finalize the ergonomics adjustment and also fit a fairing before winter. As for the intake manifold, I'd rather not touch anything, since my bike runs just fine as it is and I don't feel like tuning it...

 

A friend played magic on his computer with a photo he took of my bike.

 

"trask is on!!! "

Durham Man I did the balloon test, getting air pressure, also getting a little oil out of the breather on hard runs even though I',m running a half quart low. Trask suggests doing just the trans cover, did you vent the heads outside of the air breather also?

 

NG, no I did not vent the heads. I hear the trask is enough.

 

"I hear the trask is enough."

What I heard and read a few hours ago. Getting that cover soon. I'll spend the $$$ rather than fool around with that plastic cover. Thanks for the post about that cover/vent.
