I have used one on 3 bikes - all BMW's - a 9T, an F650GS and my RS. In every case it worked great to eliminate the low speed snatchyness and general low speed rough running due to the lean mixture necessary to pass current emissions requirements. That is its only function; it does not increase power or any other aspect of operation - just idle/cold starting/piddling along at low RPM in a high gear. I found it made a very welcome improvement on all three bikes but it depends on if you feel you have a problem and also about how you operate the bike. |

Zitat von MexicoMike im Beitrag #3 A good post, more verbose than mine but largely saying the same thing and explains why I do not perceive a problem with fuelling. The RS replaced a Yamaha MT(FJ)09 Tracer which had a terrible reputation for low speed jerkiness to the point there is a cottage industry reprogramming the ECUs on an otherwise very good and popular bike. I just adapted and slipped the clutch a lot. The RS in comparison is sweetness and light at low speeds. |

The only thing I would add is that, IMO, the BP is not very expensive in the BMW scheme of things and is easy to install/uninstall. Heck, I just spent the price of a BP on a new windscreen that doesn't work any better for me than the oem one did so in that regard, the BP was worth the money; the screen wasn't. |

Not sure why that happened...I didn't intend to make the point twice! :) |

Zitat von Alda im Beitrag #9 But Hawkeye, where would technology be if we never tried to improve things? We might all be (happy?) riding Harley’s... |

I installed a Booster Plug on my 2009 F650GS four years ago. It did nothing for the lean fueling or throttle response at part throttle and did not affect fuel mileage, but it did clean up a surge that I was experiencing when under full throttle. However, it was relatively cheap and easy to install on that bike.

I believe it's a bit simular to the "Accelerator", which was no more then a small cable to attach on a existing cable connection and that reduces the so-called KFR (Konstant Fahr Ruckeln I think). In principle it reduces the on/off effect of the throttle at low speeds. I haven't noticed this on my 2018 RS, but I did read in tests that the early models could have this problem.

Zitat von swedkg im Beitrag #13 That seems to have been the case for my 2009 F650GS (800cc twin).

I just came across this European alternative to the Booster Plug and it will fit the RS, too. While I still have my doubts how well these things work on modern FI closed-loop engines, if anyone wants to give it a try, the price is certainly reasonable: http://www.sol2.be/Performance/ENG/Order/page_BMW.html
