(3) when operating the motorcycle in un- usually dusly conditions, it Is recom- mended that oil changes he pertormed at more lrequeni intervals than that which is specified in the maintenance schedule; this will have a very bene- r al errect on the engine. (4) If the motorcycle is going to be stored for an extended period, the oil should be changed prior to storage. The Oll change interval lor your HONDA englne ls based on the use of oils that meet the requirements indicated in the section OIL RECOMMENDATION on page 23. on change intervals longer than those listed in the MAINTENANCE SCHEDULE 34 Wlll result in serious reductions in engine life and may affect HONDA obligation under the provisions of the new motor- cycle guarantee. 2. Oil Pressure Check To detect the condition of oil pump, it is recommended that an oil pressure check be periormed during the 12 months or 6,000 miles (10.000km) service. As this check requires a special oil pressure gauge it should be done at your HONDA dealer. An inspection of the oil tank and oil lines should also be performed at this time to insure that there is no leakage. 3. Cleaning Oil Pump Strainer The Oil pump strainer is located under the oil pump inside the crankcase oil pan. Remove the crankcase oil pan by remov- ing ten retaining bolts to dismantle the Oil pump strainer, Clean the pump strainer and sump pan thoroughly and reinstall. This operation must be performed by a qualified mechanic and should be done during 24 months or 12,000 miles (20,000 km) service, 0 Spark Plugs The NGK D’flESul or DENSO X724 ES spark plug is used as standard equipment on [he C5750. For most riding conditions this spark plug heat range number is satis- factory However if the motorcycle is going Io be operated for extended periods at extremely high speeds and near maxi- mum power in hot climates, the Spark plugs should be changed to a colder heat range number. Servicing of the spark plug is as follows. a. Detach the high tension cord cap and remove the spark plug with the specxal wrench provided in the tool kit b. Inspect the electrodes and center pore celain of the spark plug for deposits, erroded electrodes, or carbon foulingt It the spark plug deposits are heavy, or the electrodes appear to be erroded (D Spark plug gap ® Nzgative electrode excessively, replace the spark plug with a new one. If the spark plug ls carbon or wet fouled the plug can sometimes he cleaned with a spark plug cleaner when the spark plug cleaner Is not available use a stiff wire such as a pin to remove carbon, wash with fuel and dried. . Adjust the spark plug gap 6) to 0.0247 0.028inch (D.6*fl.7mm). The gap can be measured with a thickness gauge The adjustment is made by bending the negative (grounded) electrode Q). 35 d, When installingthe spark plug, it should be first screwed in finger tight and then torqued with the wrench 1/2 to 3/4 turrlt NOTE: (1) Use the spark plug wrench provided in the Honda tool kil to remove and install these spark plugs, otherwise it is possible for the plugs to become lodged in the cylinder head cavities All spark plugs must be tight. An improperly tightened plug can be be- come very hot and possibly cause damage to the engine. Never use an improper heat range spark plug. Do not attempt to dry or remove sool trom the spark plug by burning, nlgnition Timing Adjustmenl Adjustment of both the contact breaker pointgaps and ignition timing is required to establish correct ignition llming. 1.

I Clutch Adjustment The clutch should be adjusted so that the application of the clutch lever will com— pletely disengage the transmission of power. it the clutch does not completely disengage, the engine will stall when shift- ing into gear or else the motorcycle Will have the tendency to creep even with the clutch lever disengaged. However, in the other case, it the Clutch does not fully engage, the clutch will slip and the motorcycle will not accelerate in response to the acceleration of the engine In order for the full engine output to be delivered to the rear wheel, it is necessary to have the clutch properly adjusted. 46 NOTE: The normal dutch lever tree play is measured 0.4~1.0in. t1D~25mm) at lever end before the clutch starts to disengage.

Proper maintenance will help to,extend service life and ensure smooth power transmission to the rear wheel. Poor maintenance can cause premature wear or damage to the drive chain and sprockets. The drive chain must be checked and serviced as necessary, after the first 500 miles (wokm) of operation, and at least every 500 miles (800km) thereafter. if your CB 750 is operated at sustained high speeds, or under conditions of trequent rapid accelerallon, the drive chain must be serviced more often. Inspection Place the motorcycle on its center stand, with transmission in neutral, Turn the rear wheel slowly, and inspect the drive chain and sprockets for any of 48 the following conditions: DRIVE CHAIN ~Damaged Rollers - Loose Pins -Dry or Rusted Links rKinked or Binding Links ~ Excessive Wear - Improper Adiustment SPROCKETS . Excessively Worn Teeth tBroken or Damaged Teeth Drive chain with damaged rollers or loose pins must be replaced. Chain which ap- pears dry, or shows signs or rust, requires supplemental lubrication. Klnked or bind- ing links should be thoroughly lubricated and worked free. if links cannot be freed the chain must be replaced. Measuring Drive Chain Wear Measure a section oi drive chain to deter- mine whether the chain is worn beyond its service limit. Put the transmission in gear, then turn the rear wheel forward until the lower section of the chain is pulled taut. With the chain held taut, and any stiff joints straightened measure the distance between a span of 20 pins, from pin center to pin center. In a new CB 750 drive chain, this distance will measure 117/li". (each pitch:5/8in.). ll the distance exceeds 12l/ain. the chain is worn out and must be replaced After the chain is MLasmu a mi or 20 ins H9 pilthzsl axe-aim mrwxmxwrmrmremo Service lell ‘ l2}§iit. >l measured, shift the transmission into neutral again beiore proceeding with in— spection and service. Measuring Drive Chain Slack Check drive chain slack at a point midway between the drive sprocket and the i ar wheel sprocket, Move the chain up and down with your fingers, and measure the amount of slack. Drive chain slack is ad- iusted to approximately 3/4in.. Slack be comes greater as the chain wears. if chain slack is found to exceed a maximum of 1‘/zin., the drive chain must be readjusted. Drive chain slack should remain fairly constant as the wheel is turned If slack 49 increases ur decreases markedly in certain sections of the chain, this indicates that some of the links are either kinked or have worn pins Inspecting Ihe Sprocket Inspect the drive sprocket and rear wheel sprocket for damage or wear. The left rear crankcase cover must be removed for a access to the drive sprocket. Excessively worn sprocket teeth have a hooked and asymmetric appearance.

Bout chain and sprockels musl be in good Coud n, or Ihe new replacement chain or sprocket will wear rapidly. Lubrication Every HONDA ca 750 motorcycle is equip- ped with an automatic drive chain oiler which lubricales the drive chain with engine oil as ihe motorcycle is operated. The chain oiler is designed to deliver a maximum volume of oil at speeds between 50 and 70 M.P.H. (ao~110km/H) Supple- mental lubrication is required if your CB 750 motorcycle is operated at sustained speeds beyond this range, or whenever the drlve chain links appear dry. The chain oiler is located at the center of the drive sprocket. For access to the drive sprocket and chain oiler, it is neces- sary to remove the left rear crankcase cover. ® Adjusting screw ® on reserve clement (Z) Finnl drive shnl‘lplug (E) stopper plate (g) sz luck washer ® Nylon insert @ on passage @ Fin-I drive an.“ 4; Orifice rubber 5.

Supplemental Lubrication The drive chain must be properly lubrica- ted at all times or rapid wear will occur. Sustained high speed operation, or reduced oilcr output, may result In inadequate lubrication. lf drive chain rollers 0r SIdC plates appear dry or show evidence of rust, apply a good quality (haln lubricant according to the manufacturer’s instrucr 52 tions. Commercially prepared drive chain lubricant may be purchased at most motorcycle shops Slowly rotate the rear wheel, and saturate each link so that lubricant will thoroughly pcriclrale the area between link plates, rollers, and pins. it the chain is excessit;eiy dirty, clean with a brush and solvent, then wrpe dry with a clean rag, prior to lubrication Adjustmenl Driye chain slack should be checked. and adiusted as necessary. After the first 500 miles (HOOkm) of operation and at least every 500 miles (800km) thereafter. CB 750 motorcycles operated at sustained high speeds, or under conditions at frequent rapid acceleralion, may require more fre- quent adiustment The procedure tor drive chain adjustment is as follows. 1 Place the motorcycle on its center stand, with transmission in neutral. 2. Remove cotter pin (D from the rear axle nut C2), and loosen the nut. 3. Loosen lock nuts © on both adjusting bolts (9. 4. Turn both adjusting bolts an equal number of turns until the correct drive chain tension is obtained. Turn adius— tlng bolts clockwise to tighten the chain, or counterclockwise to provide more slack. Adjust to provlde approximately 3/4 inch (20mm) of chain slack at a point midway between the drive sprocket and the rear wheel sprocket. Rotate the rear wheel and recheck slack at other sections of the chain. slack must not be less than 3/4 “16"! (20min) at a point midway between the sprockets, regardless of the chain section at which measurement is taken. 5, Check rear axle alignment with the index marks on the rear swinging arm. Both left and right marks should corre- spond. If the axle appears misaligned, turn the left or right adjusting bolt until marks correspond on both sides of the rear swinging arm 6‘ Tighten both adjusting bolt lock nuts. 7. Tighten the axle nut and install the cotter pin. Replace the cotter pin if it IS broken or appears damaged. 8. check rear brake pedal free travel. When the rear wheel is repositioned to adiust drive chaln slack, brake pedal free travel is also affected Refer to page 59 for lirakc adlustmcnt instruc- tions 9. Remove the motorcycle from its center 53 stand While sitting on the machine, roll it forward or back to be certain there are no tight spots in the chain With the motorcycle on its wheels and laden with the rider's weight, the rear Swmging arm moves toward a horizon- tal position, and drive chain slack decreases. Drive chain slack should not be less than ‘l/2inch (13mm) with the motorcycle on its wheels and laden. Master Link, Drive Chain, and Sprocket Replacement HONDA C3750 motorcycles of current manufacture are equipped with continuous riveted drive chain, The master link is permanently staked in place; there is no removable retaining clip Master link strength and security is an extremely important factor governing the durability of the drive chain. Riveted (staked) master links are stronger and more securely installed than clip type master 54 links. Riveted master links are therelore recommended as replacement equipment for all HONDA CB 750 motorcycles. Continuous riveted drive chain can be removed from the motorcycle only by breaking the master link. installation of a new master link requires the use of a special tool. Continuous riveted drive chain, therefore, should never be removed, unless it requires replacement due to dam- age or wear. Replacement should be per- formed by an authorized HONDA motor— cycle dealer. 0 Brake Inspection and Adjustment Brakes are items of personal saiety and should always be maintained In proper adjustment. 1. Front Brake The C8 750 front brake is a hydraulic ope- rated caliper/disc type. This type brake will provide reliable operation and excels lent braking qualities at much higher operating temperatures than the drum type brake. When the brake lever is applied, brake fluid iransmits the pressure to the brake piston in the caliper, pressing the friction pads against the disc. Brake fluid is a medium for transmitting pressure and plays a vital roll in the brake system Therefore when scheduled brake mainten- ance is performed, it is imperative that the front brake system is inspected to In— sure that there is no fluid leakage. As the friction pads wear, additional fluid is taken into the system from the fluid reservoir to compensate for the friction pad wear. Because of this feature, the disc brake is self adiusting and the brake control lever free travel will remain con- stant once the free travel has been estab- lished and providing the hydraulic system is free of air. If the control lever free travel becomes excessive and the friction pads are not worn beyond the recommended limit (page 57), there is probably air in the brake system and it must be bled 2. Replenishing Brake Fluid The brake fluid level in the reservoir must be checked at regular intervals as in the MAINTENANCE SCHEDULE (page 29) and replenished whenever the level is lower than the level mark (D engraved inside the reservoir. Remove the reservoir cap Q), and diaphragm ® and fill the reservoir to the lever mark. Use only brake fluid which is designated "DOT 3” on the container. “DOT 3” brake fluid meets 55 the SAE 11703 specification. Outside the U.S.A., Use SAE [1703 brake fluid, Remr stall the dlapharagm and tlghtcn the re- servoir can securely. 3. Bleeding The Brake System The brakes must be bled with great care subsequent to work performed on the brake system, when the lever becomes soft or spongy or when lever travel ls excessive Thls procedure IS best perfor» mcd by two mechanics, . e (t) Bleeder hose 56 9' n a. Remove the dust cap from the bleeder valve and attach bleeder hose 6). Place the free end of the bleeder hose into a glass container which has some hydraulic brake fluid in it so that the end of the hose (an be submerged. Fill the reservoir wlth only the recom- mended brake fluid. Screw the cap partially on the reservoir to prevent entry of dust. Rapidly pump the brake lever several ® Reservoir cap ® Diaphragm (D Level line times untll pressure can be felt, holding the lever tight, open the bleeder valve by about one half turn and squeeze the lever all the way down. Do not release the lever until the bleeder valve has been closed again, Repeat this procedure until bubbles cease to appear in the fluid at the end of the hose, . Remove the bleeder hose, tighten the bleeder valve and install the bleeder valve dust cap. 00 not allow the fluid reservoir to become empty during the bleeding operation as this will allow air to enter the system again Replenish the fluid as olten as necessary Whlle bleeding. . Check for proper ettect of bleeding and absence of leaks in the front brake lines while holding pressure against the brake lever. 9' Replenish fluid In the reservoir when bleeding is completed. Reinstall the diar phragm and reservoir Cap and tighten. When the hydraulic brake system has been drained. it Should be first filled as outlined below. Fill the fluid reservoir , Open the bleeder valve by one half turn, squeeze the brake lever. close the valve and release the brake lever. This procedure must be repeated in this sequence until hydraulic fluid begins to flow through the blecder hose. Havlng filled the hydraulic system with fluid, proceed with the actual bleeding operation, NOTE: 1. Brake fluid which has been pumped out of the system musl not be used again. 2‘ Brake fluid will damage the paint finish and instrument gauge lenses. 57 4. Brake Caliper Adiuslmenl Whenever the brake pads are replaced the brake caliper (I? must be aditlsted This adiustment is made in the following manner, so there IS a small clearance between the fixed friction pad ;2» and the brake disc. a. Raise the front wheel oil the ground using a suitable prop. b Loosen the caliper stopper bolt lock nut @. c. Using a suitable screw drlver turn the stopper ® bolt in direction ® until the trietion pad contact the brake disc. When the wheel is rotated, some resis- tance should be noticed. d. While rotating the front wheel, turn the stopper bolt in direction (3: until the front wheel rotates treely. e. Turn the stopper bolt in direction (E 1/2 turn further and tighten the lock nut. 58 {D Brlke cllipzr (a) Stepper bolt lock nnl @ Brlke pens @ Stoyper bolt 5. Brake Pads Brake pad wear WI” depend upon the severity of usage, type of driving and condition oi the reads. it may be expected that the pads will wear faster on dirty and wet roads. Visually inspect the pads during all regular service intervals to determine the pad wear. The remaining thickness at pad linings can be determined by measuring the clearance between the face of the caliper inner housing and the brake disc by pressing the inner housing toward the disc, If clearance is less than 0.1Zin. (311mm) replace with new pads as a 56!. NOTE: Use only HONDA genuine re- placemenl iriciion pails offered by authorized HONDA dealers: when service is necessary on the brakes, consult your HONDA dealer. 6. Rear Brake Adjustment The rear brake is of an Internally expande mg type To check the rear brake pedal (D for free travel, raise the rear wheel off the ground by supporting the motorcycle with the main stand Then hand~rotate the wheel measuring the distance the pedal can move before the brake is applied Normal tree travel is approx.1in.(25mm) as measured at the tip of the pedals If readjustment IS necessary, turn the adjust- mg nut C2), in either direction Turning the nut clockwrse will increase the free travel, and vice versa. The stop bolt (3) IS provided to make a adlustrnent of the pedal height before the ad|usrmenl by the nuts To turn this bolt, loosen the lock nut. Upon adjusting, tighten the lock nut.

Espea cially inspect the Condition of wheel rim and spoke tension at regular intervals as in the MAINTENANCE SCHEDULE (page 37). It is recommended that retightening oI spokes be done by a qualified mechanic. 0 Tires If any one item would have to be singled out as the most important to motorcycle safety, it would probably be the tires. Yet, this is frequently the most neglected item on the motorcycle. Because the tires can be inspected easily, we recommended that you make it a matter of habit to check the condition of the tires during the PRE- RIDING INSPECTION. 1. Tire lnilalion Pressure Correct inflation pressure will provide maximum stability, riding comfort and tire life. To insure the proper tire inflation pressure for your particular requirements, follow the recommendations in the fol- lowing table. l
