I decided to make one myself, but went with the Mr Gasket version instead (the backing plate was chrome instead of silver). It was about $4 more, but I like the chrome better. Only other differences are that it uses a 6mm bolt instead of a 1/4-20 one, and the face plate is a little different (has a little ring in the middle around the bolt hole). I also dyed the filter black

This is on a 2002 Softail, so it's for Twin Cams too

Back plate installed. Didn't want to take any chances here so I used loctite and lock washers. I did not use any other backing plate behind it, simply a gasket. I love how it doesn't stick out



All installed





Clearance



Dunno how it performs yet, bike still has some work to do before it's ready for the road (nearing the end of a major overhaul). I had a Hypercharger on there before, so this could only be an improvement. Plus I figure if the filter is open 360 degrees and is larger than the throttle body opening, it shouldn't be starving it for air. I also love how much more open the engine is now (I removed the horn and relocated the coil to open the other side up)

 

Just watch that thing that holds the filter, it's very flimsy..

 

Thanks mreed...
Perfect

 

Wondering .....???? Will this work out for my ride , I have a close loop efi 2014 forty eight . What would be needed? A tune up or will my computer sensor compensate for the air flow adjustment. I want rid of my GIANT HAM CAN!! But strap for cash! Any input would be greatly appreciated. FTW everyone

 

I'd like to know that too mate. My leg hits the filter housing sometimes. This mod looks loverly

 

Question, if I do this on my '90 883 with a ham can would I have to to anything to the carb besides mixture, if that? Also, do you adjust the mixture like a car w/a carb-dial it in until it stumbles then back it out?

Thanks,
Jim

Here is what I have:

This is a one of those Blue filters.

 

you will prolly be good with just adjusting the 'low' mix at the screw on the bottom of the carb...if that doesn't do it for you will have to rejet the big (main) jet up one size....and to do the low speed adjustment, instead of screwing it in until it stumbles and then back out until better, screw it out until it does not run any faster, and then back in 1/8 turn or so....the way you were doing it is called 'best lean', what you really want is 'best rich'....it may take a couple of tries to get it perfect, and you may find you need to adjust the idle speed screw to keep the idle at the correct speed...and make sure the bike is completely warmed up before making any adjustments...changing the air cleaner to freeer breathing one usually doesn't effect the slow speed operation (and mix) as much as the hi speed operation (which is why you may need to go up one size in the main jet)...after you make the adjustment to the low speed jet take the bike for a hard ride up to hiway speeds, accelerating hard up to speed and listen for pinging during acceleration,,if it pings you need a bigger main jet...

 

Wow-Thank you very much.

 

Does the hole (where there is not a mounting bolt) need to be left open or can it be covered.

Why did you leave it open-should we ('90/883 Sportster)?

Thanks,
Jim

P.S. Received all the parts today

 

Float bowl vent. Blocking that off is bad carb ju-ju
