[ROVERNET - UK] Clickety Clat

Hello again. One thing I neglected to mention previously was the top chain 
tensioner. It is easy to forget. It has to be retracted to remove the chain. 
If this wasn't done then the tensioner head falls out of the retainer and 
could make a lot of noise. The second part to this is that if the tensioner 
was properly retracted then it must be released again after the chain is 
connected. Not meaning to be insulting, it's one of those things that is 
easy to overlook.
All the best, Ron.
