[QUOTE="ET43, post: 29218, member: 62"] I looked at the Bunn system and elected not to use it because I was worried about the temperature of the incoming ( filtered ) air going in to the crank case, especially as I have been known to ride in some awfully low temperatures. I wondered if the cold air mixing with the hot air in the c/case might condense and cause custard. From what I understand, this system could be likened to having two reed valves in the system on two different places, one opening at tdc and the other at bdc so that no pressure is built up in the c/case. Their roles are reversed when the pistons move up and down the bores. You have to think about this! ET43 [/QUOTE]
