Booster plug

[Phil Jordan]

Hi all. Was trying to find out if anyone has installed a boosters plug on a 1300. I installed one into  RE650 and found it smoothed out low rev take off?
Awaiting many helpful comments

I have never heard of a booster plug, where does it connect and how does it work.

The STs have a pretty flat power curve, and pretty good off the mark..

No help from me re. a boosters plug, first I've heard of that terminology in relation to an ST1300.

There was some discussion on here a coupla years back, may be more (someone may be along soon with a link) re. the 1300 engine being not so smooth at low revs, particularly when trying to keep the throttle / revs smooth when corning and also when accelerating out of a corner  Is this something you're trying to resolve?

OK, Just looked it up.

I dont think it will have much effect on the ST1300, there are some guys in the states that spent serious dollars (many thousands) trying to improve the performance to no avail. At 170ish US$, its an expensive trial..

What does it do?

Finding I have bit of hesitation upon take off from standstill.  Could be I need to ride it more an get used to it as I usually ride my RE Hunter 350 to work n around town. ST1300 has aftermarket cans (delkevic) stock airfilter.

I've ridden a few ST1300s, currently have two.  As far as I know, that's not a problem common to ST1300s.

My earlier post was leading to re-setting the ECU, this is the process (it can't do any harm, what have you got to loose?):

• Disconnect battery, leave disconnected for 20 minutes, best overnight so as engine is "cold" before next steps
• Re-connect battery
• Start engine, do not touch throttle, let it fast idle (on auto choke) until engine warms up and auto choke cuts out.
• Hit "kill switch"
• Turn off ignition
• Start engine, go for ride
• See if there is an improvement
• Re-set instrument to your preferences - can be a PIA
• Report (good or bad) back here

Thank you I was thinking of that reset as i had some starting issues and cleaning starter  relay connections and fuses seems to have helped.  This is after realising battery needed replacing.
Cheers

Booster plugs are snake oil. There is an immediate change when you plug one in but then over time the ecu learns to compensate for it. Testing shows they last a few rides to a few weeks at best.

Years ago I fitted a G2 Throttle tamer which has a slightly different cam and feeds the throttle on smoother than the Honda one. https://www.g2ergo.com/shop/g2-street-stock-ratio-throttle-tube-honda/?attribute_pa_model=st1300-a-pa-03-18
