Excellent video, very informative and helpful.

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

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

[dylankeller]

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 ??

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 !

[davidlindenschmidt]

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.

do they make a tuner for a 2020 swm se500r motorcycle an if so what model number is it ?

[Iamjacobhigh]

How to adjust my idle? I have a 2015 crf450r with this tuner on it

[TheZakkmylde]

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

[pooch]

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 .

[gabrielkopp]

What is the best setting for wr250r with big gun exhaust flapper mod stock air filter??

[TyScott]

Do the lights on the unit track up and down with RPM while your riding so you can see what zone your in?

[Asoldiersaint]

Anyone know if you can use this to richen your bike to run a little cooler?

[kyleabrams]

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

[fishfingers]

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?

[pierreirving]

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?

[BladeBarn]

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

[MERRLINN]

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😯

[riders.oregon]

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.
