Pair valve removal kit from Greece!

Pair Valve Removal Kit Eliminator Kawasaki ER 6N 650 06 On | eBay

Now this really chocked me up :smile:

 

[GR rider]

Question: Would this and/or an O2 eliminator solve the bad/rough running and response issues that we hear about so often recently?

:Hmmmm:

 

[GR rider]

Looks interesting. Think I'd want some confirmation on functionality before dropping $40 (US).

I have a TBR fitted and it's certainly backfiring but I it's not bothering me at all.

I 've heard a lot about this mod and I may do it out of curiosity though.

I will give them a call tomorrow and ask them about that and the O2 sensor eliminator and if they have any legitimate reviews of the products

 

[GR rider]

Cool. It would be great to get some actual feedback/review of the unit. But it does seem like a slick concept.

So I gave them a call today and they sounded like they really know their business.
As concerns the pair valve eliminator, the facts are:

a) Backfiring is very bad for the exhaust valves either you like it or not

b) Eliminating the valve is like plugging a hole in the exhaust system so it will have a positive effect in the performance / response sector but it could be very small and thus imperceptible to some riders


Concerning the O2 eliminator kit the facts are:

a) The engine will always have the same operation characteristics as a result of the constant electronic signal. The OEM sensor is altering the fuel mixture solely for emissions purposes so it is possible that the rough running mentioned by so many members lately is indeed caused by the original settings. This is also mentioned in the product's details:

The o2 sensor in en electronic sensor located inside the exhaust and it is used to determine if the Air/Fuel ratio of an engine is rich or lean. The o2 sensors of all motorcycles are limited to catch the emission standards and in some specific throttle positions will try to lean or richen the mixture to catch the stoichometric Air/Fuel ratio. This is good for the emissions but not for the performance and smoothness of the engine.


With the elimination of the sensor:

• Improve throttle response, with smoother power delivery and more torque available
• Support FI mods like the Power Commander and other mods the require the elimination of the sensor
• Use an aftermarket exhaust that doesn't have a hole for the o2 sensor
• Disable a faulty o2 sensor

They also told me that they didn't have any problems with their products so far, for what it's worth.

I will probably try both products in June when I return from my Balkan road trip and I will let you know of my impressions then

Ok dustind and guys, my impressions after installing both eliminators are very positive

The response is greatly improved in almost every condition, especially when riding in the city and after slowing down and accelerating again from high speeds on the highway. The engine feels fuller and the running is smoother especially when the three first gears are engaged. It's also more pleasant to rev the engine higher and the backfiring is still there, only slightly muffled. The noise has also changed a bit overall. Thanks to the o2 eliminator the bike runs smoothly and stably below 4000 rpm without any variations, so I guess this would be a cheap and effective way to fix the low rpm roughness due to emissions regulations when riding in the city that we heard of so many times, even with the stock exhaust!


From what I saw, the pair valve mechanism (about as large as a pack of smokes) that is now no more on the bike and the accompanying tube form a quite large hole which is now closed and not creating a hollow sensation any more. Also, the easy way to block the pair valve with a marble leaves the sensor active and still sending signal to the ECU which doesn't seem right to me.


The packaging was good and I got both products within two days.


Overall, I would very much recommend both eliminators as they seem to offer improvement at a relatively low cost!

GR, thanks for the update! So you installed both the Smart Moto Pair valve kit and the O2 Eliminator? Sounds like installation was simple? Was there any computer issues with the O2 sensor? I'll have to see what the damage is for shipping to California.

No problem my friend, I bought both eliminators in June as I wrote before and only managed to installed them now.


The O2 eliminator just gets plugged in the connector above the gear lever and the job is done.


You may need the help of a mechanic for the pair valve eliminator though, because the fuel tank and the air box must be removed. The pair valve "mechanism" must also be unscrewed and removed along with the pipe and then you plug in the chip next to the mechanism and you are done.


If you click on the fitting instructions link of the product you will be able to see the procedure and also print it out and show it to the mechanic in order to roughly understand what you want him to do.


If you are handy with a spanner, it's really as easy as changing the air filter

A pic of the now removed pair valve along with the accompanying piping:



There's obviously no need to plug the valve itself, a hole of several cc is now closed for good and the ECU signal is taken care of by the chip

 

[GR rider]

I'll get an update from you after you've been ridding with the mod a bit longer before I take the leap I think. I'm concerned about doing any damage... not to mention I already spent my parts budget this month (new tank bag and visor). HA!

Sure, I will let you know how things are going with the new "setup" after testing it in various conditions

 

[GR rider]

Final impressions after a few miles:

The fuel consumption is totally unaffected or any changes are imperceptible by me (and you know that I am quite the nitpicker )

After a few miles in extremely hot, Greek conditions, everything still works fine and the improvement remains.

High rpm rolling acceleration feels much crisper and more immediate.

Over and out

 

[GR rider]

Awesome! I'll look into ordering and let you know when its installed.

I 'll be glad to hear your impressions if you decide to give them a try

Thanks GR for the review. I ordered the kit from Greece last week and it should be getting here this week!



I already have the tank off awaiting it to be in my mailbox. I had to clean the air filter anyway so now I'm just playing the waiting game!

You are welcome, it's small enough to fit in a regular letter envelope so I hope it will get to your mailbox fast!

On order. Wow never realized the differences between the ebay.co.uk and ebay.com sites. Made it a little confusing.

Cool, I hope it's going to work good for the both of you so that I won't have to avoid any tomatoes thrown at me hno:

 

[GR rider]

I got mine installed last night. Very easy process.

I am having one issue though...

Great, let us know what you think of it!

Pay special attention to that first ride before getting used to the changes

Unfortunately I didn't have to remove the plate so I can't help with that.

I am sure you will work out a solution though!

So, I went out for a 30 min ride today. Man it was AMAZING. The throttle felt smoother, only a few backfires. I did also have to adjust my chain so that made the ride much better as well.

If any of you are on the fence about doing it, DO IT! Get the kit that comes with everything (so the FI light doesn't come on). Thanks GR Rider! Here's my bike:

Very glad to know that you saw improvement

Enjoy your beautiful bike :cheers:

 

[GR rider]

Follow up...

I went for a 2 hour ride yesterday. Bike performed great. Minimal popping more like a light rumble. Throttle felt smooth and the shifting was nice.

Not to mention this was my first long ride with my new bars which also were a marked improvement over the stock.

Time to move on to my next project.

Great, I am glad it worked out for you too my friend!

I was on a bit of vacation and I was hoping to hear good news from the both of you

 

[GR rider]

OK guys. As promised I've posted my installation notes in the HOW TO section:

Also, an AMAZING how to guide!

Detailed and to the point :thumbup:
