Akron, Ohio | On past bikes that I have owned, it is required to synchronize the throttle bodies to each other. I looked in the manual and didn't find any thing that covered this. Also I have never seen a post regarding this. Does this not need done to the Vision? You would think with some miles and wear that this would need checked and adjusted every so often. Just asking. |

Atlanta Area | Your bike has a separate fuel injector for each cylinder... The "throttle body" is just letting air in.... |

| Nice to have a bike that has caught up to early 90's cars huh? |

| Throttle body synchronization on some fuel injected bikes is no different than syncing carbs. The throttle body assembly on our bike is preset at the factory and even though it is equipped with adjusting screws there is no need to ever mess with them. Conversely BMW boxer twins have to have their throttle bodies adjusted periodically in order to keep them in sync. This is due to the fact that they utilize cables to operate them that tend to stretch over time. Our throttle valves are connected using a short solid linkage that should never need attention. You used to have to sync the Beemer's throttle bodies at idle as well as at partial throttle. They finally incorporated servo motors that automatically keep the throttle bodies synced at idle but it is still necessary to sync them at partial throttle.

Rockford, IL | There is however a procedure that adjust the cruise cable "lash"....... http://www.vision-riders.com/bb/forums/thread-view.asp?tid=1245&pos...
Some folks have posted that this has helped smooth out cruise surging. |

This made a huge difference in my bike. Like night and day. Before the bike would surge and it take a few seconds for the cruise to kick in. Now it is instant and rock steady. |

Akron, Ohio | I had a Suzuki V-Strom before the VV. The throttle body sync needed to be checked. Some folks would check as often as every oil change. The bikes are known to come from the factory not set properly. |

AHHHH Forgot to think about the bikes with multiple throttle bodies. Thanks Marc |

Throttle body synchronizing?
