Hi there
Sorry missed your reply - thought I'd posted it on the RS site I belong to.
I'm just trying to get my RS running to my satisfaction before selling it, it's been spot on over the last year but I feel it's a little rough at the moment. Don't like passing things on unless it's right as I wouldn't like it if done to me. Balancing the TBs hasn't done it so I'm going to check valve clearances etc. A (more knowledgable) second opinion would be really helpful!
Might you be free at any time?
Ta
