I still have blow-by problems on my 05 RG, BBII with 203 cams. Have done everything that is suggested in the forum. Not a big deal but just a PIA. My HD wrech showed me a new SE kit that they use when going to high airflow filters. Basically it replaces the naked breather hoses with a plate incorporating the hoses. Price is not bad, around $50 with extra parts and gaskets. Has anyone used one of these on a bike 05 or older?
