SE Stage 1 backing plate differences
I'm looking to route the crankcase vents outside the airbox and discovered I can't do it with the stock backing plate. So... I'm rounding up parts to mount a SE Stage 1 air cleaner, obviously I have the cover I just need the 'guts' so to speak. I can do it cheaper than just buying the kit from HD.
Question I have is, is there any real differences between the 29048-04 and the 29048-07 backing plate? I've read that at first there were problems with the plate wanting to warp, I'm assuming that is the 29048-04, was it just isolated cases or was it a major problem? Is the 29048-07 the 'upgraded' part to eliminate this problem?
Also have read that there were problems with pin holes developing in the original #29044-04 filter element. Apparently the newer #29044-04B element eliminated this problem? Opinions on the SE air filter element, is it comparable to the K&N as far as air flow?

Ehh? I just drilled a big hole through the bottom of my stock backing plate and pushed the rubber hose through it.

I'm assuming you weren't using the stock air filter element then...

The 29048-07 backing plate didn't fix that warping problem ,but it's not a big deal. I've used one and it sealed ok. You can use a K&N 0900 air filter with that intake. I have a used one I would sell. PM me if you're interested.

Yes I am. Everything is stock except for the hose that I plug into the breather bolts.

Curious... the stock filter element has extensions on the back that fit up against the breather bolts/o-rings doesn't it?

If you got your external breather kit from DK Customs, they explain it in their instructions.
