Not change, but check.

 

Found a service manual online (not the russian one) for the '07 XL North American.

6. INTAKE AND EXHAUST VALVE CLEARANCE
<INTAKE SIDE ONLY> (INSPECT AND ADJUST)

1.Before checks, check that the engine oil, starter and battery
are normal. Also, set the vehicle in the following condition:
｠Engine coolant temperature: 80 - 95°C (176 - 203°F)
｠Lights and all accessories: OFF
｠Transaxle: P range
NOTE: On vehicles for Canada, the headlight, taillight, etc. remain lit even when the lighting switch is in "OFF" position but this is no problem for checks and adjustment.

2.Remove all of the ignition coils.

3.Remove the rocker cover.

4.Turn the crankshaft clockwise until the notch on the pulley is lined up with the "T" mark on the timing indicator.

5.Move the rocker arms on the No.1 and No.4 cylinders up and down by hand to determine which cylinder has its piston at the top dead center on the compression stroke. If both intake and exhaust valve rocker arms have a valve lash, the piston in the cylinder corresponding to these rocker arms
is at the top dead center on the compression stroke.

6.Valve clearance inspection and adjustment can be performed on rocker arms indicated by white arrow mark when the No.1 cylinder piston is at the top dead center on the compression stroke, and on rocker arms indicated by black arrow mark when the No.4 cylinder piston is at the top dead center on the compression stroke.

7.Measure the valve clearance for intake side. If the valve clearance is not as specified, loosen the rocker arm lock nut and adjust the clearance using a thickness gauge while turning the adjusting screw.
Standard value (hot engine): 0.20 mm (0.008 inch)
NOTE: Valve clearance check and adjustment is unnecessary for exhaust side due to auto lash adjuster installed.

8.While holding the adjusting screw with a screwdriver to prevent it from turning, tighten the lock nut to the specified torque.
Tightening torque: 9 ± 1 N·m (80 ± 9 in-lb)

9.Turn the crankshaft 360 degrees to line up the notch on the crankshaft pulley with the "T" mark on the timing indicator.

10.Repeat steps (7) and (8) on other valves for clearance adjustment.

11.Install the rocker cover.

12.Install the ignition coils.

 

i believe it's 8 thousandths, but you need to put cylinder 1 or 4 at top dead center before adjusting (4 = adjust 1, 3 and 6) then (1 = 2, 4 and 5) i could have the order wrong but you get the idea, you need an inch pound torque wrench too or do what i did - have the dealer do it, you don't want to **** up the mivec that changes clearance at 3500 rpm
