Hi all, i thought i would post up my thoughts after recently installing a “booster plug” to my 2004 gs1200.
Ever since i bought the bike, i have always thought it had a slight misfire in that it was always hesitant to rev when pulling away or riding gently or gentle acceleration. Cruising at below 2500 rpm gave a jerky/misfiring type of ride, so much so i would always ride in a gear lower than i would have liked. Hard acceleration felt strong and smooth though, so i initially thought it must be a trait of the boxer engine seeing as this was my first one. Also when idling, the revs would tend to noticeably fluctuate up and down.
After seeing a second hand booster plug going cheap, i thought i would give it a try and see if its claimed benefits would help. If not i could always sell it on again!
It took literally 5 minutes to install after removing the left hand side panels and plugging in.
Straight away my bike felt smoother and stronger at low speeds through traffic. On pulling away from standstill especially, there was no longer any need to rev the engine and slip the clutch to get away smoothly. There was no longer any lag on gentle acceleration and on gentle steady throttle the original jerkiness was gone. Hard acceleration is still the same, no better, no worse, but now i can cruise with the revs right down to 1700 with no jerky motion at all. The idle speed is also more constant now.
I must admit i am a bit anal with fuel consumption - always doing brim to brim calculations.
Previously on my work commute i was getting 53mpg.
Having just done my first tankfull with the booster, i have got 53 mpg!! I know the booster plug is meant to inject 6% more fuel in operation to work, so i was expecting a drop in mpg. So i must put the identical mpg down to the fact i am revving the bike less to get moving and can cruise in a higher gear than i could previously.
My gs feels much more drive-able now.
I dont want to sound like an advert for the thing, but for what the booster plug costs i would recommend one if yours shows the same symptoms as mine did.
Hope this helps!...
