NOTE: If the cylinder head does not come off, lightly tap on the finless portion of it with a plastic hammer.

Do not attempt to disassemble the oil pump assembly. Organize the parts in their respective groups i. Measure the inside diameter of the rocker arm and check the wear of the camshaft contacting surface.

Standard IN. Check the gasket surface of the cylinder head for distortion using a straightedge and thickness gauge. If it measures more than the service limit, replace the valve.

Rotate the cutter one or two turns. The finished valve seat should have a velvety smooth finish but not a highly polished or shiny fin- ish. This will provide a soft surface for the final seat- ing of the valve which will occur during the first few seconds of engine operation. Page 64 Be sure to install all of the parts in their original posi- tions. The camshaft runout should be checked.

Also, check the cams and journals for wear or damage. Page Cylinder ENGINE If the camshaft journal oil clearance exceeds the limit, measure the inside diameter of the camshaft journal holder and outside diameter of the camshaft journal.

Replace the camshaft or the cylinder head depending upon which one exceeds the specifica- tion. If any one of the measurements exceed the limit, overhaul the cylinder and replace the piston with an oversize piston, or replace the cylinder.

It bears the following 0. Piston ring 1st and 2nd 0. It bears the following identification mark. Measure the conrod small end inside diameter using the dial cal- ipers. If the conrod small end inside diameter exceeds the ser- vice limit, replace the conrod. NOTE: When removing the 2nd drive gear, use a gear puller and a proper attachment. Fit the snap ring to the side where the thrust Thrust is as shown in the illustration.

The rounded side should be against the gear surface. The clearance for each of the two gearshift forks plays an impor- tant role in the smoothness and positiveness of the shifting action. If a clutch drive plate is not within the ser- vice limit, replace the clutch plates as a set. NOTE: Before installing the new oil filter and oil filter cap, make sure that the spring 3 and new O-rings 4, 5 are installed cor- rectly.

Pay attention to the following points. If it does not turn quietly and smoothly, or if there are signs of any abnormalities, the bearing is defective and must be replaced as follows. The following steps require special attention or precautionary measures should be taken.

NOTE: Apply engine oil to each running and sliding part before reassembling. Page 83 Position the gearshift cam as shown so that the gearshift fork shafts can be installed easily.

When installing the engine sprocket spacer onto the driveshaft, face the grooves A toward inside. NOTE: This nut 1 has left hand threads. NOTE: Apply engine oil to the inside and outside surfaces of the spacer.

Install the new gasket washer to the bolt A. The spacer and side rails do not have a specific top or bottom when they are new. When reassem- bling used parts, install them in their original place and direc- tion. Use a new gasket to prevent gas leakage. If the crankshaft is turned without drawing the cam chain upward, the cam chain will catch between crank- case and cam chain drive sprocket. Be sure to check the valve clearance. Extreme care must be taken.

NOTE: Remove the float assembly together with the needle valve. Do not attempt to remove the four screws of the car- buretor body. Rotate the inner race by hand to inspect it for abnormal noise and smooth rotation. Replace the wheel bear- ings if there is anything unusual.

Page Reassembly Replace the brake shoes as a set, otherwise braking performance will be adversely affected. If any abnormal wear is found, replace the brake disc with a new one. Loosen the brake hose union bolt and disconnect the brake hose. Immediately wipe off any brake fluid contacting any part of the motorcycle. If any damages are found, replace the master cylinder with a new one. Never use different types of fluid or cleaning solvents such as gasoline, kerosine, etc.

Replace the removed boot clamp with a new one. Under this condition inverted condition , hold the fork for a few minutes. If any damages are found, replace the respective part with a new one. Inspect the spacers for any flaws or other damage. If any damages are found, replace the swingarm with a new one. If there is excessive play, replace the bearing with new ones.

Page Press the bearing at 4. High gas pressure caused by heat can cause an explosion. Improper use can cause damage to the vehicle and tester. NOTE: Make sure that the spark plug cap and spark plug are connected properly. Measure the pick-up coil peak voltage in the following proce- dure. Measure the resistance between the two lead wires using the multi circuit tester. If the resistance is not within the specified value, replace the stator coil with a new one.

Worn cylinder. Worn piston ring. Worn valve guide or improper valve seating. Repair or replace. Excessive valve chatter 1. Excessive valve clearance. Weak or broken valve spring. Worn camshaft. Worn or burnt camshaft journal. Noise seems to come from the piston 1. Worn gear. Worn or distorted gearshift fork. Weakened gearshift stopper spring. Worn gearshift pawl. Engine idles poorly.
