How to Install a Booster Plug on KTM 790 Duke, Including Full Review of Results. 

If the title of the video was: i install a boosterplug on my duke 390 certainly would also suit the same "issues" thst I'm having with my duke! Just order my boosterplug expecting same results! Great video and amazing bike! Congratulations ❤😊

Stumbled across your channel last week and have since been inspired to fit both the booster plug and K&N filter to my 790 and it really made a difference.Trickling along in 3rd at 30mph is no longer a stuttery chore and the bike just feels fitter all through the rev range.I've refitted my Scorpion end can which did make throttle response more jerky but no issues now.The two mods have really renewed my enthusiasm for the bike when I was considering going 890 or even Super Duke.Thanks for genuinely helpful no nonsense content, looking forward to your future vids.

Sir! I just found your channel last night, and you literally answering all the answers about the mods I want to do to my bike! class!!! Thanks a lot!!!

I tried with two on my 690 Duke, but no difference from a single one. One have to try! I talked to the man in charge at Boosterplug and well, he had a laugh! Boosterplug is a good little device to sort out those issues you explain. And it works! I did a decat and a DNA stage 2 airfilter on my 690 and it worked fine with the Boosterplug...but it was too lean. Doing all that it needs a PC5 and a runin on a Dyno or something similar. Just put a Boosterplug on my brand new 2020 790 Duke yesterday! I'm off for a lovely autumnsride! Cheers!

I'm chuffed I've found your channel pal. I expect it will blow up in years to come. Top quality content!

One of the best videos thank you, i have religiously put these on all fuel injected twins for years and i swear by them. Ducati 1200's and various KTM'S and BMW K13+1200 series all with great results. difference for me like you is low down, 20mph second gear, 30mph 3rd gear at a push, constant clutch feathering so as not to look like a newbie bucking bronco. if possible i always check the ambient temperature on the bike before and after installing and never fails to show lower values when installed. so many haters and doubters out there and all i can say is go and spend £500+ on tuners by all means while i snigger spending 20% of that for an immediate hassle free result from Booster plug. Keep them comming 👍👍

I ordered a boosterplug last week ... can't wait to install it .... my 790 already has a K&N filter .... the city I'm living in (Medellin, Colombia) sits at 5000 ft above sea level .... the best spots to ride are 2 to 3000 ft higher , so I expect a big improvement in the fuelling department ... thanks for the heads up on this rather simple mod ... will let you know how it turns out 👍. Cheers Mate 🍻

Ive just bought my 790, and ordered the booster plug right away, thanks to Your video! Cheers mate!

Thank you for this Video. I installed one and it smooths out the low end surge. Also needed since I have the K&N Air Filter and the Coober air box cover. Cat Delete and ceramic coat exhaust next.

Just pulled the trigger on one for my 790 Adventure R. I really don't have any issues with it now, but I do worry about a lean condition since I de-catted the bike. Hopefully it makes a difference, even if I don't feel anything. Cheers to a good video!

Damn, just ordered one for my 690 after seeing your video

A great review of the booster plug, thanks

yea, after riding my 790 for a month now I understand the jerking at slow speeds but for me it seems to happen in 1st gear at under 15mph. It's not terrible but it is noticeable. Also when I first crank it up if its cold out it sometimes wants to stall for the first few minutes Im on it. But other than that its great. I'm considering this booster plug but for 170 bucks not sure if its worth that to me.

Hi bolt hole biker, I really enjoyed your vlog, and found it really useful to see how the booster plug affects the 790. I think it's worth it's price tag just for the on/ off throttle response and smoother low end running if the bike! Thanks for sharing bud. 👍👍👍 New subscriber

Thank you. Just installed the BP and the K&N filter.

Great video, finally starting to see a bit more videos on the booster plug, best one I have seen yet, very detailed, I have one on my tracer 700 with arrow exhaust, baffle in, cat in, all that jazz, definitely improves idle and low end stuff, although I do get the odd few pops and bangs outta the exhaust lol, I love the bike btw, safe riding man

Brilliant channel! Just found this tonight and your videos are great! Very informative and well presented. Subscribed!

Put this on my speed triple, my a 1050 feel like a 1050 and all low end stuff sorted. Just paid for one the Duke.

I ordered and installed a Booster Plug on my 790 Duke based on your video. Initially i noticed a difference in the smoothness in the lower gears but here in Ontario, Canada we've been having some high temps (feels like 40C) and i noticed the low gear chugs again, and read a comment about the sensor being to close to the heat sources... so today i moved the sensor from the spot you had your's as well, above the radiator to under the pillion seat.. fingers crossed it helps smooth out the lower gears again. Hoping to test it this afternoon.

Great video. Was exactly what I was looking for. Will definitely be picking one up got my 790 duke.

After my first service, my 2020 feels a lot smoother.

Beautifull review, im going to look up that plug gor my ktm aswell

great vids, info and channel, thanks from australia.

Glad to have found your channel, many thanks.

The Duke 125 suffers with the same issue. Maybe a booster plug would help it?

Good info. Pick my 790 up next week. Subbed.

So i eventually got the boosterplug fitted to my 790, on the back of this video. Noticed the difference, am happy with the result. However what i thought i'd point out is something that bothered me. Basically i put the temp sensor between the metal clip loop on the front like you did. Then relalised might not be best place to locate, as directly above radiator and engine. As in the summer when in slow traffic this will heat up very quickly. And negate the boosterplug effects as the temp sensor will read much warmer than the actual air, enriching less fuel. So i ended up putting the sensor under the pillion seat near the battery where it wont be affected by engine heat.

Have you ever experienced the bike shutting off when you blip the throttle in a low rev and gear range? I have had mine shut off several times now in 2nd gear when I would try to blip the throttle. Would adding this booster plug possible fix this problem in your opinion?

Notice any change in consumption? Doesn't sound like there are any downsides to it - probably an easier solution to the PC, too! Picking up a 790 this week, so I'll look into getting one. Good video.

Has anybody combined the Bosster plug with Coober's ECU tune?

Good comprehensive review. Thanks! I have a 790 adventure R and experience the same lean surge issues. I was going to go the PC 5 route but is seems that the booster plug does the job solving the low RPM drive-ability issues for a lot less $$. I have a Dobermann pipe (Denmark) on mine which is excellent BTW.

awesome review. im thinking of getting one for my superduke gt. just subscribed!!

Just found your chanel and I'm thinking about a KTM 790 Duke and absolutely brilliant all the mods your doing. Quick question what make of screen is that you have in your KTM 790 duke ?

Hi Stephen, how is your experience after now 9 month with the Boosterplug. Has you bike (software) been updated by KTM prior adding the Boosterplug? I´m asking because I read that the behaviour of the bike especially while driving at low RPM has been improved due to software updates in 2020. Btw real good information supplied in your YT channel. Thanks a lot.

Noticed very little improvement on my 2019 USA model. Perhaps the probe location could be done better on mine. Thankfully it's easy to take off prior to dealer service. Enjoyed the video, however!

Cheers for the videos. I've just purchased my KTM 790 and ill be looking to put a booster on also. Do you have a link to the product please. Also what exhaust do you have? Sounds lush!! 😁👍 cheers keep up the good work pal.

ONE thing i dont like about Duke 790 is the slow speed jerking. its terrible, I will check this out

Great video series on the KTM 790. I was wondering if you ended up decating the bike to deal with the carbonization at the exhaust?

Hello, I'm a new subscriber to your channel, I have the exact same bike as you and I am very interested in the Booster Plug, I live in Canada, do you have a link to a website where I could purchase this device?

So .... does it also change the reading of your dashboard ambient temperature gage by approx. 20F as some reviewers have reported?

thanks for the very helpful video. I placed an order for booster plug 2 minutes after watching your video. I wanted to ask what wendscreen you have on your duke.

Great video! About the windscreen: which make is it? Thanks., Fred.

How much is the booster plug and where do I get one?

Awesome video! Lil question, If you decide to get a slip on & de cat exhaust system would you need to have a remap/tuning device?

Hi there does it make your bike idle higher?...I've got low idle on my bike... if it should help... thks

Thanks your video.. How much horse power for on the bike ?

How do you find the change in range on a fill up now with the booster fitted. Has it reduced the mpg much.?

Hi can you send a link for your windshield.and will it fit a 2020 duke 890??thanks

Hello, you have probably mentioned this someplace in a video, but I haven't watch all of them. What brand are your mirrors?

Hey great chanel. Just subbed. Ive had my 790 duke for a year now and been loving it. Know exactly what you mean regarding slow speed juddering and stuttering. It can be horrible and even worse in anything but street mode. I might give this plug a try. Cheaper than a remap. I have an arrow GP slip on and always find it looses back pressure with the baffle out. Would this booster help that also?

Sorry meant to further ask if you’ve left the o2 sensors in the exhaust?

How are KTM regarding modifications and the warranty? Specifically decat, headers, aftermarket can and map to make it fuel properly. Will they kick up a fuss if there is a warrenty issue?

Hi! Did the exhaust have the same pops and bangs with the Boosterplug??

Hi just wondering where you purchased you booster plug from thanks

Eong nek ndue duit milihe italy german america jepang.....

do you need a k&n air filter? sorry did not understand everything. I speak German ;)

Do you know the smart IAT. I think it works better

What's the brand and model of your leather jacket?

Is it possible to know which one you fitted please, i may have missed if you said it. Thanks 🤙

Where’d you get those mirrors?

Hi, I have the same issues with my SDGT on the motorway in 6th gear. Bike becomes really vibey. Have you considered dropping a tooth on the front sprocket? Do you think the booster plug would make a difference on my SDGT?

Any improvements in the top speed

What pipe are you running? I like it

So does that mean at 10 degrees a, standard bike runs the same as a boosted bike at 20 degrees 🤔

Hello. I have a question. Where can you buy such a wardrobe for motorcycle clothes? Thank you?

Little off the subject question. But what windscreen you got on there?

How do you like that seat?

So its more linear?

Ratau ngrti merekmu aku.

New sub! 🙃

In my case the BP did absolutely nothing to the horrid surges the bike has at low rpm. Total waste of money and time
