does anyone here use a krankvent? if so, how is it? any FHE would be appreciated.
Krankvent? is that a name of a specific crankcase vent?DukeDesmo said:What advantages are there of changing the Crankcase Breather other than appearance? I have seen many aftermarket versions, the reason I ask is that I seem to have a lot of oil 'leaking' from mine, I don't know if there is anything wrong or it is loose/blocked or whatever but recently it has been more messy than before;
I took this pic today and I'm planning to remove it all to see if I can find out why it's dirtier than normal, any ideas? BTW there is no significant amount of oil in the airbox - just around the breather, is it worth getting an aftermarket one? are they better, less troublesome than the stock one? can I get more power by changing?, other than the underseat tank system.
BTW, Sorry for the thread 'Hijack'.
Indeed, either it does or it doesn't - the more I learn the less I know.......Shoie said:I find this interesting because the post from Motowheels says that removing the reed valve from the crankcase breather will overwhelm the stock OEM breather box.
Isn't that what the OEM or Nichols valve does? or does it do it differently?loony888 said:that is precisely what the krankvent is supposed to do, the problem with most breathers is they wear out reasonably quickly and cannot maintain a seal. once the downward stroke on each piston has been completed, the krankvent is supposed to seal the crankcase from sucking air back in, thus maintaining the negative crankcase pressure generated by expelling excess air on the downward stroke of the pistons. if there is more pressure generated by combustion gases passing the rings, the krankvent is supposed to expel these while maintaining the negative pressure. krankvent also state that the negative pressure helps with ring seal as flutter is eliminated.
sod it! i'm buying one. i'll let you know how it works when it's installed.
