OK, sorry to bring this up again but I remembered reading something on the old site, so on searching the archives I found a link to; http://ducatisportingclub.com/xmb/viewthread.php?tid=18058
which explains various options. I don't want to go with the corsa underseat box for various reasons but am curious as to this option;
"Except for the larger oil separator volume, the advantages of the corsa system can be implemented in the stock system by hollowing-out the reed valve to remove the constriction on drainage. Alternatively, STM valveless breather connector can be used. Then use a one-way reed valve at the airbox connection. A 748RS remote breather valve works well here."
"The reed valve location is good for emissions but not for engine power and crankcase breathing. What happens is that under certain conditions, under high rpm and light load, the oil doesn't run back because of the reed valve and it builds up in the tube above the reed.
The simplest solution is to hollow out the reed assembly and leave it internally open but still hitched to the volume bottle. This allows the volume of the breather bottle to perform its function and usually gives a slight horsepower increase also.
Then, use either a 748RS reed valve in the airbox at the end of the breather hose, OR, use a Ford diverter valve (in-line one way) just before the airbox."
This sounds logical to me, so what about the 748RS reed valve - presumably this is a straight-forward install?, is this a worthwile mod? any ideas of price? and the Ford diverter valve setup also sounds interesting (cheaper too, maybe?) any part no's or links to the type of Ford valve would be useful.
Anyone tried either of these options?
