What Hughlysses said. But like I said, Erik's comments call this whole idea into question, so insert big grain of salt.
Or ask the Malaysians... |

Many times the oil is held up in the top of the head in the cam section and the pumping action of the pistons will not let it drain back down into the sump. This is a major problem with some motors if the bottom end breathing is not correct. |

It fairly common among the ducati and aprilia crowd to add extra oil for endurance racing around here. Even though most of ends up back in the airbox, quite a few of the guys who run 1098's and 848's add extra oil for TSW. I guess what we have discovered is that the 1190R(S)(X) are actually engineered to perform under these conditions without the need for a ghetto fix. I wouldn't have expected the amount of windage loss to be that great but apparently it is. |

Ghetto fix??? Well the inlines do it as well. No bike is engineered to take the stress of that race. Its a testament of how well things are actually made these days. Its yet to be seen how well the EBR does in 200 miles next year. |

The older Buells were notorious for filling the rocker covers with oil on sustained high rpm operation and added drain lines from head to crankcase were needed.
We log oil pressure on our Bonneville bikes and sustained max rpm--- talking 4-5 miles--- saw a marked drop in pressure. We run them to top of oil glass always.
That oil can fill head area and transmission will keep a bunch in suspension with sustained high rpm. |

Interesting.
Still, a whole quart!? |
