Never try to fit individual plates is the EBC recommendation. Drive case OIL is extremely important and riders should never use ATF (Automatic transmission fluid) which has been tried in the past to reduce oil drag and gain half a horsepower. It does reduce drag and it does give you a tiny HP gain, but it ruins your clutch in minutes. Always use the bike manufacturers oil and fill to the right level. Another not so clever trick used to gain a tiny power increase is to reduce the oil level in the drive-case.Fits:2003-16 Honda CRF150F2003-15 Honda CRF230F Items Included Fitments 2007 Honda CRF150F 2006 Honda CRF150F 2005 Honda CRF150F 2004 Honda CRF150F 2003 Honda CRF150F 2009 Honda CRF150R 2008 Honda CRF150R 2007 Honda CRF150R 2009 Honda CRF150R Expert 2008 Honda CRF150R Expert 2007 Honda CRF150R Expert 2019 Honda CRF230F 2017 Honda CRF230F 2016 Honda CRF230F 2015 Honda CRF230F 2014 Honda CRF230F 2013 Honda CRF230F 2012 Honda CRF230F 2009 Honda CRF230F 2008 Honda CRF230F 2007 Honda CRF230F 2006 Honda CRF230F 2005 Honda CRF230F 2004 Honda CRF230F 2003 Honda CRF230F
