After running the evac setup with clear hose i noticed way to much moisture going into the filters so i tried something different with the small filter. I used a lid off a spray can, cut a 3/4in hole through the top and put the filter in it. After one hundred kms with lots of wide open throttle no oil, mist or water and no change in rpm or top end speed. Even with a water trap/drain, alot of water made it's way up to the filters. Cheers

Perhaps another dumb question, but wont using the OEM resevior trap water and return it to the crankcase, otherwise putting it inot the oil?
 
I have to agree, they are both dumb questions.
 
The filter has mesh all around for breathing, you are covering the entire area now who is stupid.

Jim, there is a gap all the way around the filter.It does not restrict air flow and should prevent oil mist from contacting clutches. As for water running back into the engine, internal heat will evaporate it. I know the evac system works but I do not like moisture entering through the filters. Cheers
 
Moisture won't hurt your engine, though oil could cause carbon buildup.

Ever heard of injecting water into an engine? Its a fairly safe way of boosting the power a little bit. On combustion, the water evaporates (expands) to put a little more force down on the piston. Its actually a good way to make more power since it even keeps the engine clean.

ALSO, FYI... Gasoline + O2 ==> CO2 + H2O. Your engine actually MAKES water, so don't have to worry about water freezing in the engine and exhaust system.... they already thought of that.


That being said, its probably not a bad idea to keep oil splash out of the intake, though if you have water coming out the filter, on a cold day you might get that cap of yours frozen up, and watch out, it'll blow the end cap off your rocker cover and splash oil all over your clutches.
