Kawaaski FR651V - FX air box conversion

[7394]

It's hard to get perspective on the block you installed in the old air box space. Do you have dimensions for it, or another picture that better shows it's shape? I like what you did here and want to do the same. Also, is this the kit that actually shows for the the FX motor?

It was a 4x4 that I cut to size, to sit on the 4 protruding steps under the wood block. I first shaped the 4x4 so the OE filter flap would just close. And I lag screwed from everywhere there are arrows on my illustrations. Then thru the cover to hood down the bracket.
I got the canister & brackets used off ebay, for an FX 730, but put in new filters. Now depending on your elevation, you may need to re-jet to a leaner size jet.

No kit on mine, I built it my way.

Everyone considering this be advised: This will void the manufacturers warranty and is a federal EPA violation.

How could better filtering of air void a warranty or be an EPA violation, considering that Kawasaki sells the same air filtering system on the FX engine models??

I could possibly see how it would void a mfgr warranty, if the homeowner didn't seal it right or something to cause it to suck dust. But no way Jose on the EPA deal...

I get it, it is considered tampering with emissions. I'm gonna go hide now.

How could it be, when the FX has that air filter setup?

I Bet it has to be installed by some EPA certified mechanic/Tech.

The FX models have 2 bbl carbs, & FR & FS have 1 bbl carbs. So I don't see an issue. But that's me.

I was told @ the Dealer when I got my new Kawasaki, if I did that conversion. My engine warranty would be VOID.

Guess he really did not need to know that.. LOL

Did he explain what adverse consequences a better air cleaning system was going to cause?

Wouldn't adding a sock to the oval FR filter be a similar crime against the environment? Can I expect a visit from the Environment Police Agency soon?

Baldwin and Engineaire both sell large twin element 3 stage air filters for just about every engine ever made .
Mechanics who were not fully asleep during their tech classes will know that carbs are jetted to have the correct air/fuel ratio from a clean filter to a 50% blocked air filter.
Thus a brand new filter will be a touch lean & a heavily clogged filter will be a tad rich and a fully clogged filter will choke the engine.
Idiots conflate a CAR TRUCK or MOTORCYCLE engine with a governed fix speed and fixed timing mower engine.
The air?fuel requirements and in particular the air flow requirements are massively different in particular with the air flow requirements
