I can offer a useful tip... Remove the spring on the primary throttle plate that acts on the fast cold idle cam. While you will lose your fast cold idle, the engine will still start and idle just fine because the cold mix is still plenty rich to keep the cold engine running. It simply pops out with a needle nose pliers, but watch where it flies! But that's NOT all that little spring does. Whenever you let off the throttle it retards the closing of primary butterfly for a "soft landing" so you get a lot LESS engine braking when headed into corners when the primary throttle plate is held open. Removing that spring allows the primary throttle plate to SOLELY be operated by the cables with ZERO input from the ECU. Trust me, you'll love it! You will get immediate engine braking the instant you close the throttle without the ECU holding it open. I'm the first one who has ever done this mod, so let me know what you think of it.
I don't read a lot of forums, so thanks for mentioning the secondary butterfly in the throttlebody. I've been wondering why the throttle response isn't what I think it should be.
May I ask where exactly to find the graphics kit? I’ve been looking for one that’s actually decent and was also wondering if there is maybe any other color ways or combos?
I had a blue 2010 KLX250SF I bought new. I put a dynojet stage 2 kit and a FMF Q4 slip on. It would lift the front wheel into third when the pavement was hot and do 90mph. I never did anything else to it. A beautiful bike. Was wondering how the 300 is with the FI.
I got the blue bike to did not like the green one had my choice. I tinted my headlight yellow looks great and catches the people eyes in cars for safety. MOD's EJK tuner, Blue handle bars like yours, Delavic 8" stubby can, (real load) TST rear brake lights, Turn signals added water temp guage, and volt meter, airbox mod, up grade head light 4H and tinted yellow, did a custom carbon body dress up kit instead of pre-made. My maIn bike is a MT09 but this thing is a blast to ride.
Not really any updates. Changed the EJK fueling, so it gets like 60mpg highway and still does an indicated 110 mph. Different brake pads, tried a new master cylinder, went back to stock. Has about 14,000 miles on it now. Valves needed to be adjusted when I did them at 12k.
@@nathanbaeyens2856 running ejk as well, no where near 60mpg. Do you get the issue where after engine is hot, if turned off using killswitch engine light comes on?
@@JorgeNX yeah, everyone that has an ejk gets that. i turn it off with a key anyways. I run the red fuel setting as low as possible now. just as fast, way better mpg. I've gone away from the project of making it as fast as possible and back towards making it a fun daily commuter.
The air box is the most restrictive part of these engines. Air lid off, HiFlo filter, back screen cut out, tuner and exhaust with 14/45 gearing these 300's are pretty quick. I was wondering why your's was faster, seen u were 165lbs lol.
I wonder if this bike picks up better than my KTM 390 Duke Mark 2. It's got a K&N air filter, and had the airbox lid drilled with six holes. The bike has been geared up slightly and feels relaxed on the highway but still picks up very well. If I didn't have the 390, I'd have a KLX300. Well, I would but, despite Thailand manufacturing them, they are not for sale here. Very interesting video.
I have a video on my channel of me riding with my buddy on his duke390. It pulls away from me at higher speeds, but that was before I did any power mods. It might be closer now.
@@1990-t1j Most likely not. He was a much bigger rider than me as well. My bike might make up for it in the corners, but the 390 has more power for sure
Bro sick build. I’m currently building my 2023 klx300sm. And loving it. What power commander did you get for yours? I’m having trouble deciding what’s best for mine. With the current mods I’m running
Do you actually race the SM Circuit or is this just the style you like..... lol, I ask but IDKnow jak-sH!Te about racing & I limited on what I've seen on the Texas streets..... I see a fair number of this style bike & they look cool = yours is kool or kewler and dig all those graphics. You do all that too? Is it done w/ vinyl or other material? I'm looking at the KLX 300 right now so I stopped when I saw how different a look you have. Very nice. peace man
I race supermoto on the east coast of the US. You can see my other videos if you'd like. But yes, this bike is very capable on a race track and incredible fun due to how easy and forgiving it is to ride.
Yeah, I will be taking a look at your track stuff but I'm too old for any of that now. But as I've looked at bikes I figured one of the dual sports from the 350cc & down = which ever looks like it'll provide the most bang for the buck ! The KLX hits in my top 3 so I've been checking them out. Tonight I learned about the "SM" version & I really thought you'd bought the dual sport & modded it out, did a bunch of art, & walla.... an SM LQQKing bike? But then I double checked & saw that they sell the SM model. I'll be researching to see the key differences between these two models but I guess the basics are close to the same? Running into you might make me change from the dual sport to the supermoto so go figure? I'm off right now to learn the basic differences including prices but I'll yell at you when I check your racing out... thanks for the post... peace
i got a mod a never seen i put harley tires on my 23 klx 300 dual sport to make a boujy somo feel to it bc i ride 90 percent on street....nice bike bro fr
your tires are what probably gets you above jh in 0 to 60 along with your mods when you are comparing others and your skill ... 0 to 60 times could very tremendously on same bike/car with different riders drivers....dope bike though fr
My boyfriend just installed an EJK on my 300, and we put it in the same location as yours on the side of the air box. We were curious if it’s gunna catch too much heat form the exhaust pipe, and if we had to wrap it in anything?
Are you saying that switching to the full exhaust system from the stock didn't help add any power? So basically just adds a better sound and is lighter?
In reality, the ejk does very little to peak power. It's mostly an improvement to partial throttle response. EHS racing has a comprehensive dyno video to help you understand what fueling the klx needs.
@Nathan Baeyens thanks for the reply man.. watched the video and going to re-watch 17 times to understand what he was saying. Hahah.. ride safe.. and put some cams in the 300 show us what's up.
What are your EJK settings? Curious to know what you have them set at. I am running the exact same mods that you are except for the backfire screen removal. I have a Hiflofiltro air filter, KDX 200 snorkel, secondary throttle blade removed, EJK Delkavic slip on, lots of weight reduction, O2 sensor delete from peter over on facebook. The weird thing is that my bike wont hit over 90mph with all of that done too it. I am curious if I am running it too rich with my EJK. Also do you think I should remove my backfire screen?
You might find a slight gain by removing the lid entirely. For this bike, it seems like top speed is mostly an aerodynamic thing. I'm a smaller guy at 5'5. Tucking helps a lot as well.
much less rotational mass, and for me, it makes tire changes way easier. if you get a flat tire, you can repair with a 5 minute plug instead of having to remove the tire
I'd like to know the same...Im looking at a Spiegler front brake line for my 300sm, but don't want them to be the same as stock because I'm raising my bar height an inch or 2.
Love the bike, she's a badass SM , I'm here in HELL aka Long Island, just curious, what part of NY you're in? Great videos, Subbed ya and been enjoying your videos
Just ordered 15t&39t sprockets for my 2021 klx300 ds! Did you get a noticeable difference with the top speed? I had 13t on it before but missed the longer gearing. Bike has a slip on, air box lid and throttle spring removed also will be taking off the secondary throttle plate
It doesn't gain much in top speed from the gearing, it's only 1.6% longer. I would have went 37 if u could buy one, but 39 was the smallest I could find.
have you looked at the specs for the 2023, and have you done anything else? i'm waiting on one to come around I can test drive. to see if its really 10 more hp and how the mpgs are.
@Nathan Baeyens showing 33hp and 20tq. Vs previous year of 23hp and 15 tq. I hope that's crank vs wheel numbers. If not I'm going to be bummed since we have two 2022 models.
@Nathan Baeyens the more I try to look into it the more I would agree. The article must be stating crank power. It mentions the 300r. And them "sharing the same power plant". I may just change the cam and rear sprocket in mine. It still lacks just a little for me to be totally satisfied
Seems to me ya like to ride race style. Instead of tearing apart your dual sport klx and get a racing bike? This bike is like putting a set of running sneakers on an elephant
I've got a race bike too. I modded out my KLX because it was fun. Now it's even more fun. Sometimes the journey of modifying and personalizing a bike is fun in it's own way. In the end, now I have a bike that's a few seconds a lap slower than my race bike, but is reliable and street legal.
It's an electronically operated throttle blade that sits in front of the primary one. It opens more slowly and less fully than the primary, until about 6000 rpms. It serves no purpose except to slow the bike down. Removing it will give you full access to all the power the bike makes in the low-mid rpm range, and also vastly improves throttle response. The bike will crack the front wheel off the ground much more easily.
What all is needed to remove the secondary throttle blade? Is there a secondary air injecyion on this bike too? I noticed a charcoal fuel catch can by the front, around the horn. I want to get all the emission and noise reduction crap off! Any help or suggestions would be appreciated!
@@nathanbaeyens2856 did you go in through the airbox with the screwdriver? I had to remove the whole throttle body to remove that sucker. It was painful but makes the bike run much better.
Changing tires is already annoying. Having a tube inside as well is an added level of complexity that is just annoying. Tubes are also pretty heavy and add rotational mass at the furthest point of the wheel and would make the bike slightly slower to change directions. All premium spoked wheels nowadays are designed to be tubeless. The stock wheels on this bike are not premium.
@@nathanbaeyens2856 oh okay, I just pay someone to do my tires because it's an annoying job, without the right tools. Thanks for the info, love the decals on your bike they look dope!
