jimmyl Posted December 18, 2010 Report Share Posted December 18, 2010 All info in manual which I think is available to download on here somewhere. Maybe check tappets but normally don't move much. If bike goes ok and it don't get worse then maybe leave well alone assuming oil etc all looks ok. Check cam chain tensioner?? Quote Link to comment Share on other sites More sharing options...

jimmyl Posted December 19, 2010 Report Share Posted December 19, 2010 Tappets are not self adjusting - need to be checked with a feeler gauge - 2 covers on top of head. If your not confident try and get someone to assist. Quote Link to comment Share on other sites More sharing options...
