I have been e-mailing Rex since his article on engine breathers came out in MCN magazine - which was an eye opener. With a 904 BB kit and no air box I'm getting too much oil blowing out of the breather - even though I keep the oil on the low line of the eye glass. He asked for pictures of the set up. He has a lot of knowledge on the topic and deals mostly with vintage triumphs but is looking to get a handle on the problem with newer bikes. He thinks the BB kits may be overwhelming the stock breathers - which are set up to meet emissions specs and aren't doing whats best for the bikes.
