8. Start the engine and check its

power delivery and throttle re-
sponse throughout all gear rang-
es. Stop the engine and check the
spark plug condition. It should be-
gin to lighten in color.

9. Restart the motorcycle and ride it

for about 10 to 15 more minutes.
Stop the engine and check the
spark plug condition. (See page
7-6.)

10. Lastly, thoroughly check the mo-

torcycle for loose parts, oil leak-
age and any other problems.
Check all fittings and fasteners
and tighten as necessary.

TIP

Be sure to inspect and make adjust-
ments thoroughly. In particular, check
control cable slack, drive chain slack
and for loose spokes.
