Angelo, the block off plates helped? That surprises me. Better enough that you noticed it.....Great sentence, by me. My 3rd grade education comes in handy....



It makes sense, though. All those parts do end up connecting to the fuel system, more or less. At least the vapor system.


I wonder if Jessec63 has a California bike? I know, out went, thats pretty much all we see is bikes with Cal emissions. Im not sure if that extends back to where he is?

Oh yeah. It helped a lot for me. Before I did the block-off plates, My etes would get watery then I am stopped or in traffic because of the richness of the exhaust fume. Especially if I had ethanol free fuel in. There are times when ethanol free is not an option, so it is less irritating fumes.

But when I put block off plates (It is a pain! Had I known, I would have just plugged it manually), the smell of unburned gas and fumes improved significantly. Plus no popping on decelaration. I know some people think it backfire is cool (this ain't a Harley Davidson - lol), but it is the sound of an untuned a/f to me and it is annoying.

Thanks for the input everyone. I did use new gaskets when installing the exhaust. I have not checked the tank overfill, im sure i have tried to squeeze in some extra gas once or twice

I would really like to get rid of the pop on decel, and if it gets rid of my fume issue... that would be a win win. Anyone have a guide on installing block of plate, or just plugging the hole themselves?

You can plug that hole, right in the bottom of your airbox.

With what you have going on, it would probably be best to at least put hands on all those components, and see what you find.

There are a lot of YouTube videos. The good part is those systems are very similar between all motorcycles. Even a guide for a ninja 650 helps. Also, the z 1000 is the same frame and engine, so a guide for that works real y well.

If you did not remove the PAIR valve system and install the block off plates it likely the source of the popping on decel.

The easy fix is to lift the fuel tank and find the hose from the pair valve that plugs into the bottom of the air box. It will be located at the right rear corner on the bottom of the air box. Unplug that hose and put something in the end that seals it off. I have heard of some using a screw large enough to fit into the end of the hose, or even a marble of the right size. You may also want to find something to cap off the location in the bottom of the airbox where the hose was connected.

If this stops the popping you can leave it as is and it will do no harm.

Personally I prefer removal of the PAIR and installation block off plates, which is a bit of a pain in the butt to do. If you have Ivans most recent reflash you should not get a warning light from removing the PAIR. Otherwise you will need to do a jumper wire in the PAIR connector once removed.

Just search pair valve block. The easiest method is to shove a marble in the tube from the intake box to the pair valve. You can also find an appropriate size bolt and lather some silicone on it and shove it into the port from inside the airbox. It makes a pretty big difference In killing off the crackle and popping.

I like this guys videos. Obviously, hen not talking about our specific bike, but the idea is the same.




This guy shows how to block it. On your bike, Im not sure I would do this, right now, until you can prove theres no gasoline trapped in the system. Its not in our language, but the video helps.
