After the last race meeting, the engine was removed from the bike and stripped to find the cause of the "distinct rattling sound from the engine", which was identified to be a broken camchain tensioner. The plunger non-return hinge (as highlighted in the photo of an unbroken part) snapped off at the pin & the broken parts worked their way into the sump. Fortunately, there was no further damage to any other engine parts and a brand new (genuine Kawasaki) replacement part was fitted and the engine was ready to be fitted back into the bike.
Upon leaving work tonight, my plan was to fit the engine back into the bike - until my plans were thwarted by BT who decided to block the van on the drive! More updates to follow soon...
