Put this on my 2013 350 EXC-F, immediately noticed that the idle is smoother, the whole bike seems to be a little `happier` for lack of a better word. Going to bump up the accelerator pump to see what happens.
Hey, the video was very helpful thanks! I installed a cylinder works 365cc into me 2012 ktm 350 and used this tuner. the bike runs well other than at idle it sounds fine but randomly will quite and some times right when i give it throttle to get moving in first gear it does it as well, just dies. Any idea if this is the tuner or what could cause this ? played with the idle setting on the tuner and it helped a bit but still happened a couple of times
Would the JD add enough fuel for an open exhaust? All the shops keep telling me I need a vortex or GET. I have a 2017 FE 350. I mainly just chase my 6/8 year old boys. Trails only. Id like to either add an endcap or slip on exhaust, and that's really it...Thank you.
Waiting for mine to come in the mail, did you find the best setting for most power? Also have all the other aftermarket parts that you ran, let me know thanks!
Hi Jimmy, Great work as usual thank you ! Have you tested this versus the Vortex ECU and how would you compare the two ? I would like to purchase a JD or Vortex for my 450L that will be setup for GNCC/Enduro style riding in new england ! Everyone praises the Vortex over the other offerings however this may work well for me as i really only plan on a Full exhaust, Air box mod and a flywheel weight for the engine for the moment. Thanks !
Anyone having trouble or experience with this tuner for a 2021 CRF450RL? The JD picture diagram seems clear enough and I can find the throttle body plug, but I cannot find the stock wire harness plug as it shows in the JD diagram. I'm stuck .
Reeds should come out or stay in with this tuner ? I have stock exhaust and set to what jd suggests. Never played with it so don’t really know how to maximize it
will this eliminate the jerky off-on throttle transition on new ktm SXF bikes? like riding thru pits in 2nd gear it just bucks back and forth as you try to maintain smooth throttle on/off
I have 2018 fe 350 with the emissions deleted and a a end cap on the pipe. I installed the JD tunner and the bike ran and sounded great, The next day it started and then stalled and now it will not start it just dies. Any idea what could be going on?
I was thinking about getting this for my 2018 crf250r was wondering if anyones used these on a 2018 crf? I was also wondering if it helps with starting? My bike has started hard as hell since it was brand new thanks
Yes if the bike is stock the on-board electronics are tuned for that configuration if you make modifications to the bike the on-board electronics would need to be retuned that's what this box does
Hi thank you for the video, I Have been running this tuner for around 8 months now and has been great no issues. Just recently I have noticed the bike is idling incorrect. So at idle it seems to happen more so when its been ridden hard also the weather has been alot cooler than it has been in a long time as I live in a very humid place. The bike at idle will pick up the rpm's for a second or 2 the blue light at the end will disappear and the green idle light will go from flashing to staying on and lighting up one more green light. It just sounds like some one is turning the throttle the smallest amount just over idle for a second then lets off.... It has only started doing it. It is a 2019 CRF450L full yoshimura rs4 system with a unlocked ecu from the states and the intake manifold is not restricted. Any ideas?
Does not sound like an issue related to the tuner. Maybe the injector needs to be cleaned or the fuel pressure is not correct/changing. Easy to disconnect the JD Tuner and see if issues persist. If they go away, then you know it is the tuner and since it is electronic, look at connections or see if it got very wet?
Have you tried it on a TPI 2 stroke? I just bought one and going to put it on my 250 xc TPI that has a lean low throttle opening condition. I can also tell it’s a bit lean as the powervalve starts opening.
I also have a tpi that seems lean at part throttle, stutters when it starts opening the power valve and goes "ding ding" when I close it. I've just bought the jd tuner and I'll install it this week. Any suggestions on how to tune it? Maybe going richer on the yellow and yellow-blue zones? If you have already played with it I may have a base to start. Thank you.
Does it make any diffrence on dyno? I have bought this to my 2011 rmz 450, havent got the time to play around with all modes and stuff. Soon all snow are gone so i will test it more. But i got one question, if you change one mode and go to another mode, the changes i did on the mode before will be like i put it? Hope you understand and sry for my bad english hehe :)
Hi, I don't understand, please can you write here how your system works and what improves ?, I have a 2 ktm 300 2 times TPI 2019 and I have a problem with stuttering at half rpm, thanks, I'm writing from Italy
Go to the web site and search JD Jetting and I won't have to write it again. But in reference to the 300, that sounds like something else is already wrong.
Hello I have recently purchased a crf450L euro bike stock 25bhp:( how much bhp do you think the tuner would add?? Or do you have any other recommendation mods for me?? Am from the uk and there’s no parts available for them yet👎
The jd jetting 6x are not waterproof!! It caused me so many problems and caused me to get dnf on new ktm tpi. The tell you to put it on the side of the frame with wires up, there are crappy rubber seals that let water in. Do not buy or put it in your airbox
Stop babbling and point out the highs and lows. Where are the sweet spots on this module?. Not everyone is running through the desert and can actually ride. What happens when there's hill climbed involved and temps are cooler. Just Saying!!!!
Excellent video, very informative and helpful.
Glad it was helpful!

What if I don’t push any buttons? 17’500exc, I’m wondering how do I know if it gets too hot, or cool? Lean or rich? How do I tell??? Thx
do they make a tuner for a 2020 swm se500r motorcycle an if so what model number is it ?

How to adjust my idle? I have a 2015 crf450r with this tuner on it
Thank you for the info buddy!
What settings do you use for your 250l ? I’m trying to get the most out of mine. Running a full exhaust, air box mod, and k&n filter. 2017 250l ??

What is the best setting for wr250r with big gun exhaust flapper mod stock air filter??
We will answer this on tonight's episode of Tech Talk Taco Tuesday! We will be going live at 7 pm pst on our CZcams channel and Facebook page
Interesting!
Anyone know if you can use this to richen your bike to run a little cooler?
will this eliminate the jerky off-on throttle transition on new ktm SXF bikes? like riding thru pits in 2nd gear it just bucks back and forth as you try to maintain smooth throttle on/off
I can easily do that, for the most park, just like jetting a carb would.
Do the lights on the unit track up and down with RPM while your riding so you can see what zone your in?
Yea the unit has a little party while ur riding
I have 2018 fe 350 with the emissions deleted and a a end cap on the pipe.
I installed the JD tunner and the bike ran and sounded great, The next day it started and then stalled and now it will not start it just dies.
Any idea what could be going on?
We'll discuss on Tech Talk Taco Tuesday #81
Does the jD tuner come pre set like the ejk does?
Yes, they all do. And by the way, Dobeck makes them all and sell them to other companies like Bazaaz, JD etc.
I was thinking about getting this for my 2018 crf250r was wondering if anyones used these on a 2018 crf? I was also wondering if it helps with starting? My bike has started hard as hell since it was brand new thanks
So if you do mods to your bike like opening up your air box you need this devise to make use of the opened up air box? I'm a beginner to this stuff😯
Yes if the bike is stock the on-board electronics are tuned for that configuration if you make modifications to the bike the on-board electronics would need to be retuned that's what this box does

Please do EJK vs JD jetting for CRF 250L
its the same Product... Dobeck Performance which makes the EJK is also making them for JD Jetting with the Specifications JD wants
Have you tried it on a TPI 2 stroke? I just bought one and going to put it on my 250 xc TPI that has a lean low throttle opening condition. I can also tell it’s a bit lean as the powervalve starts opening.
I have and they really work well for those bikes.

Hey how's it going .did you ever figure out the JD tuner. I have the rmx450z what settings do you have it on and does it feel good Tx
Hi, I don't understand, please can you write here how your system works and what improves ?, I have a 2 ktm 300 2 times TPI 2019 and I have a problem with stuttering at half rpm, thanks, I'm writing from Italy

I have the same problem, at partial throttle openings or when cruising. I've bought the jd tuner and have to install it to see if it helps.
Hey man any chance you know why mine won’t light up and my bike won’t turn on when I try and use it?
Is it plugged in correctly? Or is the unit faulty? Only things I can think of.
Dirt Bike Test I’m starting to go with a faulty unit..
can I use the same jd jetting on a different brand of motorcycle?
No, they are specific to models.
What's the best setting for a 2013 350 xcfw?
Watch TTTT#84 for the top secret answer. Too much info to type it our and give it away.
Do a video of installation
No
Hello I have recently purchased a crf450L euro bike stock 25bhp:( how much bhp do you think the tuner would add?? Or do you have any other recommendation mods for me?? Am from the uk and there’s no parts available for them yet👎
hey its the tour of idaho rider
No, I'm the Dirt Bike Test guy...
👍🏼
The jd jetting 6x are not waterproof!! It caused me so many problems and caused me to get dnf on new ktm tpi. The tell you to put it on the side of the frame with wires up, there are crappy rubber seals that let water in. Do not buy or put it in your airbox
a simple PlasticBag sealed with a rubber ring will make it waterproof
Hi sir is this compatible with a 2014 YAMAHA YFZ450R? (Fuel Injected)
(Quad)
Is a simple piggyback
Get a Vortex ECU - Way better .. IMO
Stop babbling and point out the highs and lows. Where are the sweet spots on this module?. Not everyone is running through the desert and can actually ride. What happens when there's hill climbed involved and temps are cooler.
Just Saying!!!!
Hill Climbed settings are good because the hill is behind you.
