Those with a muzzy full system Are you experiencing a loud pop and shooting flames on deceleration at or around 3.5K rpm? I am and another guy I know is expierencing the same problem. I have a cali model with the charcoal filter installed and I'm still expericing the same pop and flames on decel. Anyone have a fix for this yet?

There are a couple of fixes available (plugging the hose, block-off plates, etc...). Try the search function and you will find a good number of threads discussing this issue.

Got my Bike back today from shop, Brock Ti, PCIII and exact same thing... 3800 to 3750 on de-cell, major pop and some flame.
When system installed, told by Kawi Mechanic that Canadian Model has no hose to block off...

You aren't 'venting' anything. The purpose of the KLEEN system is to inject additional air into the exhaust stream to enhance the combustion process and produce cleaner emissions. When you put a aftermarket exhaust on the bike, this results in the popping you hear when you are shifting gears or decellerating. By blocking the system, you prevent this additional air from entering the exhaust system. The reed valves that allow this action to happen are in the combustion heads and DRAW air in. If you were to VENT, you would in fact, be inducing a large vacumn leak into the airbox.

Take off the front hose by #4 start the bike. this hose has a vacuun on it. Rev it up this hose still has a vacuum on it leave this hose hooked up to airbox. Take off the rear hose(blow by) it is on the left side by the little tube that when it shows oil in it you take off the little cap and drain it. Run the motor holding your finger on this hose this hose will build up pressure. Block off the metal pipe that is sticking out of the airbox rear and just let the blow by vent the to outside. Front pipe takes the air from the air box ,rear pipe lets it back into the air box not exhaust system right. or am I wrong again.

The crankcase vent and the KLEEN are two different systems. One has nothing to do with the other.

OK so the clean air system is just a bogus system and uses the venturi affect to draw clean air into the exhaust system to make it look cleaner for emissions. The shop manual does not make this clear. Thanks.

On decelleration a vacuum signal opens the Kleen air valve, that lets the air flow thru the reed plates into a small port in the exhaust port area. That mixes with the unburnt gases to further combustion and reduce emissions. Like SWFT said..

ok ok I get it. Puts air into exhaust to help finish off burn, doesn't hurt performance helps make the air cleaner for our kids to breath. Thanks I will leave mine alone.

I like the flames LOL! Looks cool at night, or so I've been told by those following in my wake...I've also seen them coming from a Hayabusa with Microns and thought it looked pretty cool. Some folks have actually installed a spark plug on a wired connection just to do much the same thing.

Exactly. That's a '50s rodder trick. Put a spark plug in the exhaust near the tip and it would always ignite the unburned exhaust gasses

oj330i sorry to hijack.
Swft thanks for keeping me on track. Could no leave it alone so I hooked up the gages to air suction valve hose. Found it had vacuum on it at idle, when rpm went up or when they came down. What did happen was the mercury jumped up a bit when rpm went up but quickley came back to where it was at idle 6cm. When the throttel was shut down there was a loss of mercury but once again it returned to about 6cm. I feel that the air suction valve is more like a regulator that keeps the vacuum at a given.
I feel the air is pulled into the system by the venturi effect. When I took of the exhaust manifold I found each port had two passage ways one was clean and one was not. Hear is where the effect takes place and the clean air is pulled into the exhaust manifold and mixes as you said.
It just does not makes sence to me that the system would only work on decel.
Sorry to drag this out.

Sorry oj330i I just trying to learn more about what this beast realy is and how it realy works. To answer your question if it were me I would just leave the system hooked up. It does not hurt performance and if you let off the throttle easey it does not pop on decel.
