Whilst my engine was out, and the fact it's done 21k miles, I checked my valve clearances. Well done Honda - all within spec & mostly on the loose side, which allows for valve recess into the seats. Anyway, I used this chart to record measurements. It may be of use to someone?
@bonjo That's model year 2008 onwards mate, I believe up to 2012, not sure if they differ from then onwards. Mine's a 2010. There's no copyright claim on it, so feel free to edit! Some vertical lines in the middle of the boxes would probably help, if you can do it.
These bad boys make measuring the clearances much easier, rather than mangling a straight set. Notice they're in thousandths of an inch, which shows my age then. A metric set is a bit finer.
great I can use the same numbers as my bike is 2008 It is easy to create a new table spread sheet and as your info to it. I will give the mechanic a print out at the valve clearance service
@bonjo. Fill yer boots mate! That kind of chart was brought in to play by a garage I worked at because some of the techs would claim they'd adjusted them, just to earn the bonus. All us honest ones welcomed it because it could easily be verified. On a technical note. The cam followers don't really wear out as long as there's oil in there. The clearances tend to tighten as the valves hammer into their seats, especially when lead was removed from petrol. The lead acted as a 'cushion'. When adjusting them, it's best to go around 0.01-0.02 mm looser than 'perfect'. They'll go at least 32,000 miles before adjustment needed again. In my opinion!
a check list/ table is always good to keep the mechanic focused on the work he is doing and also for you to keep track of your machine's behaviour so a double +
