After finding a disturbing crunchy rattle some months ago, I finally decided to check out the possibilities. It did sound like a bit of steel galloping around the engine, so caution meant I must at least have a look. It did it twice at the start of a ride, both times whilst braking to a stop but none thereafter. I removed both chaincase and timing covers - mostly OK but for some swarf in the chaincase probably from my electric starter bedding in, then removed the rocker box, pulled the pushrods to get a look down onto the cam followers. Cannot find anything sofar.
