I rejetted my carb last week, got a K & N Filter and wasn't 100% pleased with the performance. The Bike just acted like it had a little more to give. I gave it some thought, so last night during the Monsoon we had, I modified the Backplate of the Air Cleaner to get some more air to the Carb. The pic is of whats left. I had already put it back together when I thought about makin' pics. Got to get some more Loctite or I would have taken it back off and I wanted to ride it first. MAN WHAT A DIFFERENCE!!!!!!
Oh it's a 05 883C
Was that the stock backplate you modified? I'm not really familiar with the K& N aircleaner. The pics of that backplate look like it started life as astock backplate. How does it now attach to the bike?

How did the bike run?
Yea it is a Stock plate, it mounts the same way now as before. the 2 crankcase breather fittings , plus the 3 screws that go thru the filter to the carb hold it on, it ran better with the Filter only, buuuuuuuuuuuuuuuut it is much more responsive now. It is a BIG difference! BIG!
The K & N is about 3/16" thicker than the factory, I had to shorten the Cover screws to get it tight on the filter.
I thought about drillin' it in several places, the more I thought about it, the more I liked it this way, wannhdawg has the Screamin' Eagle Version of what I did. His is what gave me the Idea to do it this way.
have you done anything to your mufflers yet? just a suggestion, but after a few hundred miles you might look at your plugs to see if the mixture needs any adjustment. i did my stage 1 in steps because i'm cheap. when i added the slip ons and adjusted the mixture it was like a different bike. no more card farts, higher shift speeds and more midrange power.
stay safe
I've had the SEII's for a year. Plug reading aint what it used to be now that Gas has so many "cleaning addatives". I am keeping an eye on them though. It is much better performance since I modified the back plate!! Thanks
What is the k&\\;n part that you brought to go along with this mod? This replaces the other a/c cleaner kits (s&\\;s, bs etc)? Ty and g8 diy project there!

RE: Rejet, K & N and Air Cleaner Mod
Well I think I might have found someone to help me out here. I went and purchased some drag pipes for my 883 \\;and to keep some back pressure I took some baffles out of some old mufflers I had and screwed them into them. I then jetted the carb with a 45 slow and 175 main. I then did a similar cut with the plate (like you) though I only cut like quarter moons on the sides and cut out the big *** cover plate on the bottom to reach the edge of the filter. I still do not have the punch that I wanted in fact the damn thing tops out at 90 it will not go any faster and I do not get any of that quick throttle responce that I wanted. Do you think that I should cut out more like you did? Do you have that spring loaded air trap in there as well, and \\;what did you do with that? It hooks to something electronic and I just took it off. Any help on this would be appreciated!
