Booster-plug

[pops1961]

Has anyone installed a booster-plug on their VFR 1200X and  removed the black rubber air cones on the air box, I heard this gives it a little more HP

Why on earth do you want more HP?
More HP is for at the bar and for on the road it's for top speed witch is limited so you will not gain any more and you also don't want it with the geometry of this bike.
If you want a better riding bike i'll recommand a sabsteef flash.

I got one.  Not sure the booster plug but drops intake temp to richen mixture.  I got it second hand cheap haven't bothered installing it yet.  Maybe next time I have the tank off

I bought a new Triumph T120 in 2016. That had a snatchy throttle but even more annoyingly (for me) it surged on a constant throttle at lower speeds, say 30-35mph, when riding through a town or village. So I tried a Booster plug. Took all of 5 seconds to fit, unclick one sensor on the air box and join the thing in between.

I read the bumf about it and it sort of made sense.

But did it work, err, no. The only thing I noticed was the exhaust gases smelt more 'petrolly' when ticking over. i.e. rich. Like it was on full choke. So I had visions of petrol washing bores and took it off after one run out. Flogged it on eBay at about half what I paid. Another life lesson.

Others may have had better results but for me, wouldn't bother.

I had a booster plug and K&N air filter fitted last week on my 2017 CT.  I to was experiencing uneven power delivery at 30-35mph and a somewhat snatchy throttle.  The side cones on the air intakes have been re-installed.  The bike is now smooth and easy to hold a steady 30mph.  There is more urgency in acceleration and gaining speed seems to require less revs and time.  I wouldn't say it's night and day difference, but it is different and my main aim was to eliminate the uneven 30mph drive issues.  The drive shaft no longer can be heard 'slapping' in it's housing.  Very pleased.

The Booster Plug does improve the throttle situation, however, it still has the oxygen sensors continually leaning off the mixture under certain throttle conditions. If you disconnect the O2 sensors and keep the BP connected, you're left with a straight 10%ish increase in fuel richness,  resulting in great power, lovely throttle characteristics, but offset by pretty poor fuel consumption.

My experience so far has been to simply disconnect the O2 sensors. This allows the engine to run on the fuel map that Honda intended, keeps the throttle smooth and the fuel consumption reasonable. The one downside is a permanently lit FI light.

I have no input on the booster plug, but if you are riding in town at 30-35mph and the drive shaft is banging, you are riding in too high of a gear. I know the uneven delivery at this speed exaggerates the problem but 1st and 2nd are the only gears to calm this banging.
If you disconnect the O2 sensor, the engine will run in open loop mode.

My engine is now perfectly behaved in any gear or situation. I certainly wouldn't want to have to use 1st and 2nd gears at 30mph. My DCT version selects 5th at about 30mph on a steady light throttle.
Yes correct if you disconnect the O2 sensors, the engine just runs on the predetermined map and without trying to lean off to meet emissions rules.
