Does anyone sell an authentic looking air cleaner element- 29036-56?

Yes, Fram CA77 is as close as it gets next to NOS of course.

The K&N E2470 is another option that flows significantly more air than a CA77.

A paper air filter or oiled foam air filter will filter out significantly more dust and dirt.

Murph - I tried a Fram CA77 on my 1962 XLCH, and it would barely run - the motor was gasping for breath. Took it out and the motor ran perfectly.

Years ago, I looked up the applications for a CA77, and found it used on various lawn/garden equipment, like riding lawn mowers, roto-tillers, and other things with decidedly smaller engines, and consequently less air flow requirements.

I was thinking for show/judging/display. I’ll use a K&N for running it.

Interesting, I run them in all the sportsters I've ever done and had no issues. I'll take it out and see if there is a major difference next time out and report back.

Well, I've been known to be wrong before. Perhaps more often than I care to admit!

All I know is that I took out the copper mesh and put in a brand-new CA77. The bike ran fine at idle, but terrible at speed. I followed the basic scientific method, which is: undo the last thing you did. I put the copper mesh back in, and it ran fine. End of experiment.

Well, perhaps I got a bad filter. Or installed it inside out. Perhaps the high-speed needle needed to be leaned out. I didn't try anything.

Murph - we're waiting with baited breath for the results of your experiments. Maybe that Hennessey guy is just full of stuff, and has misled the tribe - and all those guys who have followed his advice and have been oiling their copper mesh packs will roast him for dinner when they find out they coulda just used a $5 throwaway paper filter.

From abroad, I dont get it: an original air filter element for show purposes?
Do them judges really open the filter cover?
How about aftermarket engine internals?
How far do they dig in?
K&N chains?
I can understand the personal satisfaction of having everything spot on like when the it left The Factory- but is better really worse under these circumstances??

The way I understand the judging rules is that the judges are not allowed to touch the bike.

When my bike was judged, the main judge scolded the other judge for opening the key switch cover to see if an original key switch was below. With that in mind, I’m not sure how they can see the air filter under the cover.

By the way, I enjoy when Hennessey makes fun of Hennessey in the earlier post! Ha ha.
