I would take a serious look at the new Suzuki DR4 coming out before buying another KLX300. Good little bikes but down on power big time unless you can find the Japanese ECU that will work with this bike.

Do more videos on your klx300r

Im doing these mods to mine thanks. If you get that tuner make sure you do a video on the installation

Use the kdx snorkel

Which one is better first gen Durango or the second gen

Why not completely remove airbox cover?

I appreciate this video. Very informative.

I gotta 230r but same idea I just have a air cooled bike little less power but I’m gonna check this out tmr my bikes a little lighter so jumps don’t really have any issues but I hate getting gapped by 250’s im barley slower too

Where did u get your foot pegs

Where did u get your bigger foot pegs?

Did you get tuner for this?

garbage

Just cut the back side of the snorkel out (creates a window) to the air filter. Actually I think I works better than switching snorkels

Not all same type sensor work the same. On klx, by allowing more inlet air flow it actually runs richer.

Do you still have the stock exhaust? Would you sell it?

If you're reading this, JUST INCASE you do everything by the book, and your truck still does not turn on. It could be a bad lift pump that is located behind your filter housing (about $200) or a CP3 pump (about 1 hour and a half job to remove). Bad injectors could also be a culprit. So just an FYI to anyone reading this.

Did you have to change out the? Rear leaf, spring shackle hangers ? If so where did you get them ?

Take off the air box lid and throw it away. Take a look at any MX bike airbox and you will understand why. And no it will not lean out your bike and burn the piston. Only a bench racer will tell you that. Your EFI will compensate on it's own. I just bought a 2025 KLX300 to go along with my plated 21 WR450F. The first thing I'm doing is putting on a FMF Powercore and chucking the air box lid. I'll let you know if I burn a piston.

Hi! Does this exhaust have a lambda sensor input? To be able to connect it to the klx 300 dual sport

Pull the lever Kronck........Wroooong leverrrrer

This removal of the snorkel is quite similar to the DRZ400 3X3 Mod to the air-box. Of course, doing that one would need to change the jet and needle in the carb. Yours has no carb, but is injected. You may need to have it flashed. The sparky-plug doesn't really look lean to me. It looks about right. But yes, keeping the plug darker means keeping the engine' combustion chamber cooler is a good thing. I think you are safe. Especially if it doesn't feel lean either.

Picking up mine on Saturday. Thanks for the pro tips! Do you notice any real problems after the mods? Thanks

Why is no one doing the full exhaust ? only the slip on pro circuit offers a full exhaust for this bike ?

Beautifully detailed!

You don't need to grease it they have a good enough seal just oiled and held on with the bolt

unrestricted airflow will cause an catastrophic engine failure on 4 stroke engines. Also, running it too rich in the same setup will make things worse. A engine with such low performance output will suffer from these mods more than you actually gain. But each their own.

Hey bro ,mine a sounds like a jet getting ready to take off,,,what it could be,, I just bought the truck is a 2008 ram 6.7 it looks like the fan clutch has reassunly changed

Any problems with the bike running lean? Any tunes needed? Also did it fit fine or did you need to make any changes to the mount?

No

Cool video. To the point, well done. I am gonna purchase a klx300r next week. Do you have a skid plate on that bike, and where did you get it? Thanks; Tony.

Cool cheap mods. And I like cheap. Anyhow, do those mods void the warranty? I am guessing you bought that bike new. Did you have to take it to the dealer for a xxxxxx mile checkup? Thank you.

Iv been telling people this for years on these KLX. They are not lean from the factory, too many people just repeat phrases they hear AND cant read a spark plug. Iv got 700 miles on my '24 with the snorkel out, more grunt and plug looks fine here.

Thank for the video! Great info! I have the same bike. Do you notice any decel pop? I hear some on straightways and was wondering if it’s normal.

Fuel mixture and high compression is the reasons why European cars required higher octane fuel because the engine runs lean and hot so they have to prevent pre-ignition. It is regulation now that motor manufacturers have lean fuel settings whether it is chainsaws, lawnmowers and even large, diesel, tractors etc.

Yes, but keep this in mind if you hit some deep water at speed your engine will be toast.

Grey/black = rich ! White insulator = lean. A proper air:fuel mixture will result in a light-TAN colored center insulator (NOT grey/black, as you showed.)

If the bike was already lean, increasing all the air flow in the airbox and out the exhaust without increasing the fuel is making it even more lean. Common sense

Lost me at keepin it oem. Soooo much stuff on the 3rd gens have junk oem parts.

Did you end up having to get a fuel tuner? if so which one did you get?

has the bike got good power even with out the mods?

Makes sense to me, nice bike

I have the 2022 model and I installed a pro circuit t6 slip on it sounds great good compression and all..but my header pipe is stock and it glows red like bad is there anything I can do to fix that? Besides getting a aftermarket header

I just wanna say that your DURANGO looks awesome, I have a 98 DURANGO and it sounds fairly simple to do this modification and your video is super informative. Thank you for showing what steps you took, you have inspired me to make the changes to my DURANGO and go from boring to badass 😎

I wouldn't recommend removing the airbox lid without fuel controller changes, like using an EJK. They are already very lean from the factory, opening the airbox will make it moreso

On the issue of CV Joints not even a concern, think about it if you are driving and turn L or R the angle is so much greater on the CV joint then any angle I see right now with the CV joint and the Lift I would be much more worried about the sway bar and the distance between it sitting static and when the suspension is topped out (IE tires off ground) Good video though very good job and well explained :)

Looks like u needed one more sub to reach 500 so I got u covered. 👍🏻

If I do 2” lift shackles and crank front tortion keys would I be able to fit 33s or 35s on welds and 1” spacers so they stick out a little bit more

Would 33 x 12.5s fit without lifting? Spacing? I* have 31 x 10.5 on my 99 SLT+ 5.9. I'd like the wider tires for Beach fishing!
