I prefer to check clearances prior to the maintenance recommendations. While checking, gives you some time to check out the CCT. (cam chain tensioner).

Measure the valve clearances with a feeler gauge. Turn the motor so that the bottom of the cam, not the lobe, is over the bucket or tappet and measure gap. Check the correct value with the manual.

Contrary to what's been posted, valves with a screw and locknut adjuster tend to slacken overtime and get noisy because of wear in the rocker arm and in the adjuster. The constant hammering tends to ease the adjuster over time. This tends to be greater than the wear at the valve seat.

Valves with a bucket and shim adjustment are only affected by valve seat wear, and tend to get tighter and quieter.

If you have bucket and shim tappets, use a micrometer to check the actual thickness of any shim that you need to change before calculating the required replacement. Numbers stamped on the shims aren't always to be trusted.

And to add to Rob's statment, make sure you log the shim size that you have taken out and put in. This will help on the next valve adjustment and save time.

 

yuppers as mentioned. Keep a good record
