Which member just wrote me and told me that venting the valve cover won't work because exhaust comes through. I say this one more time in case you missed it. When you remove the Kawasaki Clean Air System and your airbox. There is nothing there to recirclate. You can remove the reeds and tee the hoses together a run a hose with a small filter in it.
You can take the crankcase breather hose that went to the bottom of the air box and put a filter in it. And if you, you so desire you can run one filter at the crankcase hose down by the transmission and use just that one alone as in by itself. I have my reasons for running two small filters and if some say it's overkill, waste, won't work Fine they didn't have to pay for it. But If it does work and works well I am sure everyone will want to jump on the bandwagon. I did it, I like it, it's going to stay that way ,it's over.
