This article is not entirely correct.... there are many mass produced engines that run greater than 100% VE without forced induction.

The mass produced Honda H22 (Prelude, Accord, Ect) runs at 104% VE and does not have any form of Forced induction. There are also several production street bikes that run at greater than 130% VE.

I've never heard of sleeve valve engines failing due to "popping"...Generally, I believe their biggest issue is sealing oil.

Helmholtz resonators have been used after the 70's. Many cars today use them to remove drops in torque at a certain rpm (e.g. Honda gen. 2 L-series).

moreover the volumetric efficiency should be defined on the mass basis not on the volume as the volume occupied by the air fuel charge will always be equal to that of the cylinder —Preceding unsigned comment added by 59.160.18.209 (talk) 04:55, 18 August 2008 (UTC)[reply]

These motorbikes can only attain this efficencty by driving at speed where air is forced into the air intakes, this is not possible at static conditions.
