Booster Plug Review and Other Assorted Observations

The only thing the boosterplug does, is lowering the actual temperature reading from the temperature sensor. So the ecu thinks inlet temperature is lower. The mixture is than richer. More fuel. Thats all.
It has is own temp sensor. The reading is outside the airfilter box. Its connect to the original temp connector. So their is nothing special about it.

A stuck thermostat in th ST1300 effectively does the same thing. Who wants reduced fuel mileage for something easily adapted to?

That's my experience too.

Won't go so far as to say the throttle is not "twitchy", just as I won't say some 1300s don't experience high-speed weaves or some 1300s don't get overly warm.

But none of this has been my experience with my 2008 model. The modern fuel injection (if you can call a 17yo bike "modern") is very linear to me, never snatchy if I use my hands correctly, which is most of the time by far, and is smoothly predictable in its power delivery.

Same for my BMW 1250.

I attribute this to proper fuel injection mapping, but I've never been a hot rodding hooligan, and I may not have the calibrated seat of the pants that some motorheads and riders may have... a road racer, foe example, may nit pick this motor to death.

But that's not me, either. I love this bike and the motor and the available power, just as it is.

Honda got it right with the ST, IMO.

They have a graph on their site to support their claim that they do a much better job keeping the enrichment stable near 6% over a wider temperature range than comparable competing devices.

They do, however, acknowledge that the enrichment takes off, like it does with the other guys, above temperatures "you would normally not ride in".

Problem is......here in Houston Tx, our Summer Temps are never down to what they seem to think is a "normal" range.

When i bought my st1300 it has already the boosterplug. I do not like aftermarket things that mess with the ecu. I have the bike brought by a forum member that synchronize the valve throttle body's. And give it a little love and care. I find it not aggressive on the throttle. It rides very smooth without the boosterplug.
It is better to adjust your bike than put aftermarket things on your bike.

:rofl1: As if that's stopped most anybody. But the review is appreciated. Have you checked your plugs to see if they showed a richer mixture? Interesting about getting more pop than without the BP. On other bikes I only noticed that in an overly lean condition.

About the wing as a lip- I usually ride looking through the windshield (heresy!) and get no helmet buffeting. Riding just looking over the top of it I get noticeable buffeting and increased wind noise. I'd think a lip could be adjusted to reduce that. This wasn't the case or wasn't an issue for you?


I thought as much too. I imagine it might be possible to encounter "natural" circumstances to which it couldn't adapt. Enter the Booster Plug artificially effecting change. It's interesting that it seemed to smooth out low end throttle response.bI'm not considering in getting the BP but actual usage reviews are interesting.

Doesn't sound inviting, but curious what the *&%$% is a booster plug? A different type of spark plug? Some other kind of plug? I have an 09 1300A and average 42 mpg, love the acceleration.
