NOTE: Fig 5-24 shows one of the methods mea-
suring the crankshaft side clearance between the
machined face of the crankcase and shims. As a
paper packing is used on the machined face of
the crankcase, adjust the clearance by taking this
thickness of 0.22mm into account.
5-4-6 INTAKE AND EXHAUST VALVES
Remove carbon and gum deposite from the valves, valve seats, intake and exhaust ports and valve
guides.
NOTE: If the valve face is dinted or warped, replace the valve with new one.
NOTE: If there is an excessive clearance between the valve guide and valve stem, replace the valve
guide with a spare. For replacing, pull out the valve guide, using the valve guide puller as shown in Fig.
5-26, and press fit a new valve guide into place.
