In OHC engines valve seat recession causes clearances to lessen, but much, much less than clearances changed in pushrod engines. In my last bike, a 1250 Bandit, valve adjustments were considered rare up to very high mileages. This is why I think 09 exhausts are set to the tight side of spec at the factory. Yamaha don''t expect them to change much.
current personal DL650 has not needed the valves adjusting again in over 95,000km after the initial adjustment at 25,000km. Preparation. Remove the seat, fuel tank side covers, lift and remove fuel tank. To make access much easier I also remove the entire front end ''cockpit'' in one lump (not necessary on the earlier Generation 1 models).
