Booster Plug

[dewi sant]

Nooooooooooo! Totally wrong place, don't touch those they're to do with the fuel injection. Not sure what you have to move if it's a GS but on the 1200R you need to lift the back of the fuel tank and prop it up. You'll then find a large black box - which is the airbox and on top of that you'll find the air temp sensor. Unplug the lead from it and insert the booster plug in-line...i.e plug one boosterplug lead into the air temp sensor and the other into the lead you've just removed - they'll only fit one way round as one will male and the other female

Have had mine on and off; if yours in an R12, you have to lift the tank to do it; not where you are in the pictures. I'm going to put mine back in; had it off bc had bike tuned at same time and had to work out what was creating a problem; problems now solved so plug can go back but you have to lift the tank. Not a big deal but more than I want to do. I think the plug you are after is up and toward the triple clamp under the tank.

Nowhere near the triple clamp, it's on top of the airbox - simples. Lift the tank and you'll see it

But to lift the tank you have to remove left side trim panels, plus forward trim panel on right side, then the bolt which holds tank on left side. I think about 8 screws in all. No great hardship but a little time consuming! The metal tube thingy you mention is a temperature sensor and I just laod mine under the seat.
Hope this and other answers helps.

Thanks for the help. Now that I know where to look I can make another attempt. I just need to ride the bike to reduce the amount of gas in the tank.

By reading this thread I am convinced I would like a Booster Plug based on subjective measures. The Boosterplug website shows at $149. Not sure it is worth that investment...

Then I guess your only somewhat 'convinced'.

Has anyone declared the Booster plug to their insurers? I wonder what the reaction might be. Probably use it as an excuse to load your premium even though it has little effect on performance. On the other hand if you do not declare it and you have claim they could refuse to settle.

[jkhomes]

I am also convinced I need headers and upgraded shocks, but haven't been able to rationalize those costs either. Are their better prices for booster plugs?

If modifications affected insurance, many of us would be uninsurable...

A few years ago their was a group purchase on Adventure Rider (I think) that resulted in a generous discount from the manufacturer. A few people on this list (including myself) got in on that buy, but now it seems the going price is $149.

Here's an article from, I assume, someone that makes no profit from the sales of Power Plugs: http://www.webbikeworld.com/t2/booster-plug/

Users like the Boosterplug, as well as its half-price competition the Accelerator.

Just to stir the pot - I'm not moved to buy either - you might review this thread on ADV Rider, where the poster took an F800 Boosterplug, opened it up, and took photos: http://f800riders.org/forum/showthread. ... tor-module

The Boosterplug discussed is the Mark 1 version; the maker is now on the Mark 2, which is a potted assembly and not subject to easy surgery. Still, if this is all that's going on, I'd think that what you're getting can capably be done for far less than the Boosterplug's price. If this tweak appealed to me, I'd be more interested in an Accelerator.

Thanks to all for the tips and instructions on installing the Booster Plug. Bought a used one on the cheap and installed it yesterday. Took me about an hour plus but I am old and slow. Some observations from the install: Removed both trim panels on both sides of bike. I zip tied the new sensor to the intake horn on the right side of the bike so that it was far enough back not to be visible when the panels are in place. An old plastic rally mug makes an excellent brace to support the tank without scratching the paint. I cut a small piece of tubing to go around the original sensor wire where it goes thru the carrier clip on the airbox to prevent chafing and cutting the wire. If I completely remove the tank in the future I will do a better job of zip tying the Booster Plug module to something as I don't want it rubbing on anything when the tank is in place. Plan to ride on Sunday so that will be the proof of the pudding.

P.S. Have a smoke Ztechnik 18" (Plexi only no brackets} and a Givi 147 (Plexi only no brackets) PM if interested

I just installed mine too (finally).

Right now, I've just got the sensor taped to the intake. I'll move it later if I decided to leave it installed. I took a short ride and I'm sorry to say I didn't notice much difference. I'll live with it a while though. I need to take a longer ride of the stop-and-go variety. It's on those kind of rides that I was annoyed by throttle abruptness.

If you don't notice some at least some difference than you're one of the lucky ones who has a bike that's ok - some are worse than others it would seem.

After having gone for another ride, I think there is some improvement. It's subtle, but it's there.

[celticus]

I ran my sensor into the air intake scoop.
The difference is nice but subtle. I really have my doubts about a dyno difference. I've never even been in the same room with a dyno. I've got one on my bike. If you want one get one. No difference to me. Now the Lennies Sprockets , those are less subtle.

Got mine today and heart in throat, I installed it.

1/2 hour give or take and I went S L O W!

Worried about dislodging something under the gas tank, but overall it worked out fine.

I zip tied the sensor to a wire on the side of the air box under the plug connection - between the tank and the air box. Should be out of the heat area.

Difference was immediate and dramatic. The surge or on/off I experienced in 1st and 2nd gear is gone. Same for the engine braking being more subtle and not so dramatic now. Roll on the throttle and it works like you'd expect, not on/off, just a regular roll on of power.

Should be standard equipment.

I suppose my bike - R1200R 2012 - was a more needy example and had the problem worse than others.

I finally installed my group buy booster plug last week and I can attest to the above. This has improved the low speed performance so much
that it feels like I've got a new bike. I couldn't be more happy.

For those who haven't seen much improvement, I wonder if the position of the sensor could be a factor. I mounted mine forward of the gas
tank to try to get as close to ambient air temp as possible. At low speed, which is where the effect is most desired, having it in obstructed
air flow may prevent it from changing the temperature map enough. Just a thought.

I think it's more to do with how bad it was beforehand. There will be minor diferences that vary from bike to bike as the way they're set up in the factory or at the dealer will only have to be within a certain tolerance - so they'll not all be set up exactly the same. Any aftermarket mods will make a difference too, I found the snatchiness in my bike got less after fitting the Akrapovich end can. Also a lot will depend on how you ride. My bike wasn't too bad, but I knew there was a slight problem due to the bit of jerkiness at small throttle openings. Fitting the Boosterplug didn't make an earth shattering difference but a lot of the "on /off" characteristic of the throttle has now gone making it more pleasurable to ride at low speed.

I really wanted to get an Akrapovich---now you've given me a reason!
