there is no reason to think again !i too can post some photos of cranks with fat and thin conter weights its point less ! there not that fat ! 24mm is about average for most conter weights . there is no big plus to knife edging the 944 crank !it will not give you more hp or make the motor last any longer .there is no big problem with windage with the 944 motors . the cost don't out weigh the plus fo doing it . if you want to spend the money to do so than do it . i have on some of my motors and there is no plus to it .the 944 motor max rpm is about 6200 the shift point is about 6000 not a rev happy motor . the first # in oil is cold cranking weight 20w winter 20 weight and so on . we only use a 50 weight oil on every hot days . day that are over 100 degrees . other than that we use 40 weight in all 6 of the teams 944's . our fealing is that the 50 weight only is to thick to get proper flow throw the oil passages . it was the teams choose 3 years ago to start using 40 weight most of the time after a run of spinning barings . we feal it was the right move becouse we have not spon a baring sence then . one of the enduro 944's has 3 years of racing on it 5 24 hour races 3 12 hour races and 6 6 hour races on it along with a hand full of sprint races . other than timimg belts and oil changes we just keep running it .

Windage is an issue with ANY engine.
A 944 engine is less suceptable to it than many, but it is certainly not immune to it. Anything that one can do to eliminate or reduce it is free horsepower and free minimization of (many) other potential problems.

windage is only a issue if it gives you a issue ! and its not with a low reving 944 motors . but like i stated before if you want to spend 1000 to 1500 dollars to get at most 1/2 hp go for it ! i did with 2 of my motors . one of the motors we did a knife edge and rebalance on it only turned 1/2 more hp on the motor dino . and a motor that turns at most 6200 rpms oil cavition is not an issue !
