This looks like it's pretty close to the heavy breather filter.

looks like mine,the s.e. replacement is 75.00,how much is that k&n???

 

On ebay it's about 46 bucks.

Is that $75 buying it from a dealer?

 

yes,thats from a dealer. will look at my parts sheet if i can find it and check zanottis price.

 

part # is 29424-05,includes chrome band clamp cover and clamp. rain sock is 29493-05.

 

I agree 100%

My dad installed one on his road glide (carb bike) and when summer came closer he started having pinging issues (switched from K&N setup). So we figured a tune was in order. Took the bike to a very reputible tuner in the area and after a couple hours on the dyno some things were discovered.

1. The engine had too high compression for the cams---bad build? (not by us!)

2. The engine needed a bigger jet than a 240....on a 44cv, 95"engine! to keep from running lean and pinging.

3. Front and rear cylinders have a huge afr difference. Compression test shows exactly same compression.

Tunner suggested.....Get rid of the SE heavy breather! Air and fuel getting rammed into front cylinder while rear cylinder was lean...Seems the air was making the 90* turn into the carb and kept trying to continue its curving path right into the front cylinder blowing right past the rear.

Installed SE K&N style filter setup and AFr's front to rear were almost exactly the same. Rejetted the carb and with octane booster...no pinging and runs a ton better!!

 

i"ve also heard they dont work well on carbs,but on fuel injected bikes i"ve seen 2 to 3 h.p. gained over the stage one. big advantage pulling cool air away from the engine heat. tha stage 1s are getting alot of heat off the motor pulling from the backside of the football cover.

 

Yeah, that's the one, Vic. I got tunnel vision just looking at the 2.5" flange diameter units, and missed that near-exact fit just a few rows up the table...nice catch. They say the flange will stretch about 1/16", so the 2.44" flange size would be just right. Those oval tapers I linked to might look pretty sweet.

The stock HB element has the chrome base/flange cover; I didn't look to see if this might be transferrable to one of the K&N's that look like they have a plain, black rubber base/flange. If so, that would be a big incentive to replace with the one you found over the oval taper element.
