i recently broke down on my moterbike its a T reg R6 it went into the bike shop to be repaired, a week passed before they told me they wouldnt be prepared to take it apart to see what the problem was, so i had to get another bike shop to pick it up and attemp to repair it. its finaly been 4 weeks and they have estimated a �550 bill to replace 2 valves and repair the cam chain. should i write off to the bike magazines and highlite the problem with trying to get anything other than a routine service carried out and should i be contacting Yamaha and try to get some kind of compensation for the failure of the cam chian in an engine that has only done 6000 miles
