Honda have quoted me £350 plus parts to do the 8000 mile service on my 2008 Transalp. The service includes a check on valve clearances. I would like to have the Honda stamp in the book but it seems a bit early for a valve check to me, and the price seems a lot for a sub 4k bike. I could just do a regular service and forget about the stamp in the book. Or would I regret it? What do others think?
