Installation with Stock Pushrods Refer to the service manual for your motorcycle model. Installation with Adjustable Pushrods Lifter-Cover Removal Installing or removing the pushrods with the valve train loaded can result in engine damage. On the cylinder being serviced, always set the lifters to the base circle on the cam before servicing pushrods, lifters, rocker arms, and valves. 1. Set the lifters of the rear cylinder to their lowest point, or base circle, on the cam. Refer to Setting the Lifters to the Base Circle in this instruction sheet. 2. See Figure 1. Insert a screwdriver into the slot on the side of the spring-cap retainer on the pushrod cover. 3. Press the spring-cap and retainer down while pulling outward to remove the spring-cap retainer. 4. See Figure 2. Lift the lower pushrod cover to reveal the lower third of the pushrod. 5. If the engine has stock pushrods installed and you are installing adjustable pushrods with this lifter-cover installation, go to step 6. If the engine already has adjustable pushrods installed and you are installing adjustable pushrods with this lifter-cover installation, go to step 7 6. Use a bolt cutter or similar tool to cut the stock pushrod. Avoid cutting the pushrods with a saw, grinder, or other method that may allow metal debris into the engine. Go to step 8. 7. Loosen the jam nut on each adjustable pushrod and resize each rod to its shortest length. 8. Remove the pushrod covers and pushrods from the engine. 9. Remove the O-rings from the seats in the engine at the top and bottom of the pushrod cover. 10. Remove the four screws fastening the lifter cover to the engine to remove the cover and gasket. 11. Remove old lifter-cover gasket material from the engine, taking care not to allow material to fall into the engine. Continue to Lifter-Cover Installation in this I-Sheet. Lifter-Cover Installation 1. See Figure 3. Verify that the lifter anti-rotation pin is in position. Installing or removing the pushrods with the valve train loaded can result in engine damage. On the cylinder being serviced, always set the lifters to the base circle on the cam before servicing pushrods, lifters, rocker arms, and valves. 2. Verify that the cylinder lifters are set to their lowest point, or base circle, on the cam. Refer to Setting the Lifters to the Base Circle in this instruction sheet. 3. Fasten the new lifter-cover gasket and chrome billet lifter cover to the engine using the chrome screws from this kit. In a cross pattern, torque the lifter-cover screws to 90 – 120 in-lbs (10.2 – 13.6 Nm). 4. See Figure 4. Loosen the jam nut on all of the pushrods and adjust the pushrods to their shortest length. NOTE See Figures 4 and 5. Install the narrow-band pushrods in the cylinder-intake location. Install the wide-band pushrods in the cylinder-exhaust location. 5. Assemble the O-rings (purchased separately) and pushrod covers. 6. Install the pushrods with the pushrod covers. The adjustment-end of the pushrod must be on the lifter

Clean the air filter Pull off the right-hand side panel and remove the two nuts which secure the air filter cover. Withdraw the cover, checking that the sealing gasket is in good condition, pull out the retaining spring and withdraw the element assembly. Peel off the inner and outer foam sleeves. Wash all components in white spirit (Stoddard solvent) or in warm water and detergent and dry them thoroughly. Soak the foam sleeves in the specified oil, then squeeze them gently (do not wring them out or they will be damaged) to expel all surplus oil. Refit the sleeves to the element frame. On reassembly ensure that all components are correctly fitted so that unfiltered air cannot bypass the element. 2 Check the spark plug Remove the spark plug cap, unscrew the plug and check its condition, comparing it with the photographs on page 65. If it is badly worn or fouled it must be renewed. If it is fit for further service check the gap and reset it if necessary, as described in Chapter 3.8. 3 Check the valve clearances It is important that the correct valve clearance is maintained. A small amount of free play is designed into the valve train to allow for expansion of the various components. If the setting deviates greatly from that specified, a marked drop in performance will be evident. In the case of the clearance becoming too great, it will be found that valve operation will be noisy, and performance will drop off as a result of the valves not opening fully. If on the other hand, the clearance is too small the valves may not close completely. This will not only cause loss of compression, but will also cause the valves to burn out very quickly. In extreme cases, a valve head may strike the piston crown, causing extensive damage to the engine. The clearances should be checked and adjusted with a cold engine. Place the machine on its centre stand and remove the rocker cover, taking care not to damage the 0 ring. Remove the gearchange pedal and the left-hand outer cover to expose the generator rotor. Remove plug and allow old oil to drain Remove the spark plug, then slowly rotate the engine anticlockwise by way of the generator rotor, watching the inlet valve. When it has opened and closed again (sunk down and risen up to its original position), rotate the engine further until the T mark on the rotor periphery aligns exactly with the raised index mark which is positioned between 12 and 1 o’clock (from the crankshaft) on the generator stator. The engine will then be in the correct position for checking the valve clearances, namely at Top Dead Centre (TDC) on the compression stroke; check that there is free play at both rockers. Using a 0.08 mm (0.003 in) feeler gauge, check the clearance between the top of each valve stem and its corresponding rocker. The feeler gauge must be a light sliding fit, with the rocker and valve stem just nipping it. If necessary, slacken the locknut, and turn the small square-headed adjuster to obtain the correct setting. Tighten the locknut, holding the adjuster at the same time to prevent it from moving. Finally, recheck the setting and then repeat the procedure on the other rocker. 4 Check the contact breaker points and ignition timing Note: since the generator stator plate is located by its countersunk retaining screws, the ignition timing can only be altered by opening or closing the contact breaker gap; therefore both operations are described as one. The full procedure is given here for ease of reference, but if the points are found to be in good condition and if the gap has not altered or is within the tolerance, then the ignition timing will be sufficiently accurate and there will be no need to carry out the full check. First remove the gearchange pedal, the left-hand outer cover, the spark plug and the left-hand side panel
