KLX300r -pair valve before and after (Delete)

the simplest thing you could possibly do with no mechanical experience ever to make your bike stop backfiring ,( disclaimer ) do this at your own risk , im not responsible for your bike sounding better only you are :)

[@KandySoufax]

PAIR feeds excess throttle body fuel/air back into the hot exhaust causing it to combust instead of going out into the air. Part of why the stock bike gets so hot. The header and pipe are cooking off the waist fuel/air from the throttle body causing backfire. What a dumb regulation shortcut by Kawi.

[@spelle2237]

Ahhh thanks have the same bike with the same exhaust with same tuner (judging by your sticker) thought this might be a tuning issue now to find the plugs u used

[@spelle2237]

Finally got around to doing this amazing the difference bike runs great now thanks for the video/help

[@Differentthingsstandup]

Where can I get the tube for this fix?

[@normichtrailrider.7343]

You don't need a hose , if you have a pair valve you just block it ,

[@user-kt1bv3kx4f]

Im in michigan. Will you get fd with by dnr for your pipe and valve delete

[@scramblygerry9069]

what braces do you have on your radiator? having troubble finding some for my 2021, already bent the right one. >.

[@normichtrailrider.7343]

Stock !

[@PaytinJohnson]

So what is the PAIR valve doing now that it’s capped? Isn’t there a purpose to it?

[@cobysize333]

Does it hurt the bike I want to do it?

[@klxcurtis3925]

I know this was 5 months ago but I was curious did you have to delete the o2 sensor on the exhaust as well?

[@normichtrailrider.7343]

No

[@kawikah6301]

Isn't it just lean? Shouldn't you adjust the fuel map in the ECU so it doesn't run hot and backfire? I only ask because I have the same problem with my pipes glowing red hot, so I know it's a fuel map issue...

[@at5252008]

Nice job getting ready to the same to mine. Are you running power commander too?

[@normichtrailrider.7343]

Yes.

[@peytonnorris1343]

The power commander isn't needed right. also was it worth the money and does it give better porformance

[@normichtrailrider.7343]

Changes the bike a lot , why else would they make them it's not a placebo effect , buy one and try it yourself .

[@louiscatapano7021]

I have the same set up. With power Commador v. What exactly is it that he capped.

[@normichtrailrider.7343]

Did you watch the video or even listen?

[@louiscatapano7021]

@@normichtrailrider.7343 Yes I did two times, I look up what the pair valve is and i will delete it same way you did. Very helpful. Thanks

[@BigOSac]

was this the reason for the recall on the bike?

[@ronaldwriston1546]

No.

[@NANA-qn8on]

That sound would drive me insane.

[@JusitnP]

What does this do for the bike. Are you loosing anything because of this change

[@normichtrailrider.7343]

Did you watch the video ?

[@JusitnP]

@@normichtrailrider.7343 yes but why did that stop the excess backfire? What purpose is that hose and what does it do for the bike

[@JusitnP]

@@normichtrailrider.7343 did you do something like a "pair eliminator" so it doesn't show a check engine light?

[@normichtrailrider.7343]

Watch the video again and then re think your questions

[@kevroq6139]

Does nothing but stop backfire stranger if your question is if there's any gains...no

[@peytonnorris1343]

I plugged and capped mine but it still backfires

[@normichtrailrider.7343]

What kind of bike and pipe ?

[@triple6758]

Pull all that junk off and put a blocking plate on the valve. May see CEL after. There's a module available to solve that issue.

[@killerX9979]

Do you know where to get the plates from?

[@triple6758]

@@killerX9979 Mine came from eBay. Not strictly a 'legal' item in some instances. "KLX pair valve block off". You'll also need a module from smart moto to keep the CEL off. Good luck

[@sammcbride2464]

Not really backfire. More like fuel loading up.

[@normichtrailrider.7343]

It's my bike I ride it it backfires what do you know ?

[@sammcbride2464]

@@normichtrailrider.7343 Well, I have been riding for over 50 years. Fuel loading is a bit different than backfire. I wasn't trying to be nasty. Good that you fixed it though.

[@sammcbride2464]

Technically, a backfire is when it backfires through the intake valves and carb. A backfire is really bad and has been misused for fuel loading since the 70's. Fuel loading is when the fuel is not fully burned in the combustion chamber and is ignited after the exhaust value by hot components like a header or collected in a muffler and when it gets to a critical amount and fires. There are other types of issues like ignition timing, valve timing or the way the intake butterfly closes when the throttle is released and the fuel ratio changes and creates either a fuel load issue or lean fire issue. All of the latter 3 issues will pop out the exhaust pipe. When I built cars in the 70's you would often see a backfire with flames coming out of the carb.

[@RedboneUnincorporated]

Does this trigger your warning light?

[@normichtrailrider.7343]

No issues
