- Install and review of the Booster Plug. Very big improvement noticed. My bike is also running a NGK Iridium plug. Both make the ride even better on my Himalayan.

These are the best and clearest videos for servicing that I have ever seen... Clearly you put a lot of thought and preparation. Thank you for taking the trouble
thanks man, installed one today 2021 himalyan and instant idles well, much more tractable bottom to midrange. Nice!
Very clear install. PLEASE though ALWAYS cut your Cable - Zip ties FLUSH with No bits sticking out. They make VERY sharp knives. Cheers
You can always just melt the end cut parts slightly with a lighter, to smooth and round them out - I've always done it.
Thanks so much for sharing 😊. Will be adding to my Himalayan. New follower.
Good Video! why is the Compass blinking ?
For 2023 model the engine has the same tuning as the scrambler 411 eliminating starting issues and the need for that idle lever.
A lot more of mission putting booster plug on than on Interceptor.
On Interceptor takes about 1min no tank removal.They are good richens up the fuel so it not so lean & perfect in hot conditions letting ECU thinking it's 10° colder so great in summer.
Lucky guys you interceptor riders :)
Thx for the video :) What blinkers did you put ? They look nice :)
Super helpful. Amazing video. I am going to install my Boosterplug in a few minutes.
Please do more videos on Himalayan
Hello Max from WA! Please give your sweet, beautiful Momma a hug. Thanks for sharing your videos
Hello! I’ll give her one :). Best wishes
Same here! Absolutely an improvement :)
Just rev it a bit after starting. Job done!
That won’t fix the very lean mixture unfortunately
I did one of these on my tu250x. Significant improvement. Even more so with a k&n filter and muffler installed. I wonder how it would work on one of these?
If the Himalayan is set up to run lean in order to pass emissions testing, and the booster plug makes the bike run richer, aren't you at risk of not passing an emissions test?
Mine still stalls and fails to start in the cold. Battery is fine. Booster plug fitted.
HAVE YOU REPLACED THE FACTORY PLUG WITH THE NGK IRIDIUM CR8EIX 4218 PLUG? I BOUGHT ONE BUT WITH ONLY 200 MILES ON THE ENGINE I WILL WAIT A COUPLE OF HUNDRED MILES. THANKS FOR THE DETAILED VIDEO... JOHN IN CO.
Yes I have swapped for a NGK plug - that helped as well
I also installed the NGK Iridium plug a few thousand kilometers ago. This also helped a lot. Especially in low RPMs. And it also leads to a better overall performance with smoother engine running and harmonic power development. It feels like having more torque. Installation of the Iridium plug was a very good decision. Now i am going to install the Boosterplug. Let’s see if it even gets better…
Nice!
Great job. Good info. God bless. Happy trails.
If I just increase the idle RPM (loosening the screw under the tank) would that also work?
What does the booster do exactly?
Booster loops the fuel signal so it adds more fuel - these bikes run very lean and hot from factory (especially the fuel injection models) so I’d recommend the booster as it mends the real issue.
@@EC-M4X Ok so if I understand correctly :
By loosening the idle-RPM screw, I just increase idle air intake, and injectors adjust to it. RPM increase but the mixture ratio is still lean.
With the booster plug, the whole ratio is corrected to a bit less lean. RPM is the same but the engine doesn't stall.
@@KhaleyJo Thats correct it will fix the lean running no matter the RPM or Idle adjustments- it adds fuel to the whole map.
Mine is the same but give her a couple of twists and she comes right pretty quick...
Hello how are you?
I hope you are well.
What is the function of that item you installed?
Where to buy this? Excellent video by the way.
What is the maximum speed it can go after installing booster??
thanks......I'm doing this👍
Did RE fix this issue on the 22 model?
I believe I read that the ecu’s on the 22 and up models can’t be modified with the booster plug so a different method is needed.
@@EC-M4X Thank you
I have the 22 model and i switched out the stock mufler and let me tel hou it runs super the bike just Needs more air
or you could just use the choke to start the bike. I see in the video your choke is off.
Yep however this adds fuel to the entire mixture across the rev range - choke only will aid cold start idle rpm
Just using the choke lever (fast idle circuit) didn’t work on my 2021 Himalayan. It would start run for a while and then stall several times before fully warmed. Often it would stall at lights or when stopped in traffic. Dealer had it ten weeks. It runs much better now but is still running lean.
@@EC-M4X is your exhaust in the video stock? If it is, it sounds good! I'm debating to install an aftermarket exhaust.
@@davidmead8990 Yep I still have the stock exhaust on it, thanks for watching!
Is this the booster plug (2017-2020)? On your 2021 RE?
It fits 2021 models if they have they grey connector shown.
@@EC-M4X Excellent, thanks for getting back to me on this.. I will buy mine now :) Have you had any problems with the relay on you Himi?
@@dagamercat8666 no relay issues yet - I believe the 2022 US models had more issues than the previous years
Could just rev it up a few time when you first start it.
I have - still a far to lean mixture. Summer heat would have it dying out at lights on me.
Isn't it awkward working on stuff with all that man-jewlery, spent years servicing farm equipment didn't wear wedding ring nor watch was afraid it'd get snagged & loose fingers
Haha sometimes - I take them off when any power tools are involved
