1) Remove OEM Tensioner: On some models including the 250F motors, it may be necessary to put the engine at TDC before proceeding. Check your manual. This is not the case on the 450 and 530 single cam motors. • Remove the outer cover plug. • Remove the large cover with copper washer. • Using needle nose pliers grab the end of the OEM tensioner and pull it outward. Be careful not to damage the aluminum port or face. • If the O-ring did not come out with the tensioner, carefully reach into the port and remove it without pushing it further into the engine. 2) Install new Tensioner: • To prepare the new tensioner, set the spring aside. Put the new tensioner in the collapsed position. (They are packaged and shipped in the collapsed position.) If you have extended it, rotate the assembly until the “top” on the piston is facing up. Then a light tap from the bottom will release the ratchet. This will now allow the plunger to be retracted to about 1- 13/16″ (46mm). • Install the O-ring over the tensioner body, keeping it outboard of the ridge as shown. • Slide the tensioner assembly with O-ring (without the spring), into the engine port. The end (with the hex-head spring hole) should only protrude from the engine about 1/32″ (.75mm). • Install the cover and tighten. The copper washer should be tight. • Insert the spring through the cover port. As it is slowly inserted, you may hear clicks as it pushes the plunger inward while ratcheting. • Install and tighten the plug against the spring. Note: some 250F engines have a one piece cap. Slide the spring into the tensioner far enough to hold it, then capture it with the cap and tighten. • Start the engine and carefully check for oil leaks. Adjustment will occur internally as it is needed. No further maintenance of the tensioner is required

Cleaning and Relubrication Perhaps the largest contributor to shortened chain life is inadequate lubrica- tion. All working parts of a chain should be lubricated uniformly. The use of the highest viscosity oil that allows for flow between the link plates and coats pin-bushing areas will normally provide the greatest wear resistance. Apply oil to the upper edges of link plates. This allows for the greatest access of oil to pin-bushing joints. For open drives, excess lubrication on outer chain surfaces should be removed, since it will either be thrown off during operation or serve to collect foreign materials. If foreign objects or surplus lubrication accumulates on chain surfaces to the extent of making re-lubrication of the joints impossible, the chain must be cleaned. Standard roller chains may be cleaned by washing in kerosene or any other good petroleum-based solvent. WARNING: These solvents are flammable. Agitate the chain to assure penetration of the solvent and a thorough flushing of the pin-bushing areas. Drain off excess solvent and inspect bushings and pins for wear. Replace the chain if wear is excessive or parts are fractured or missing. O-ring chains may be cleaned externallyby washing in kerosene. Do not use any other cleaning agent or the O-rings may be damaged. When cleaning O- ring chain, clean only the external areas of the chain. Do not attempt to force kerosene into the pin-bush cavity. Do not try to repair a worn-out chain by replacing individual links. The pitch of the new links will be shorter and will most likely result in chain fatigue failure and/or severe sprocket damage. For chains which are still usable, soak them in SAE 40 or 50 automotive engine oil (without additives). Flexing the chain in oil will assure greater penetration of lubricant. Inspect and clean sprockets. If sprockets are worn or damaged, they should be replaced.Installing new chain on worn out sprockets will significantly shorten the chain’s service life. WARNING: always wear eye protection when assembling or disassembling chain

Remove the 4 bolts that hold the exhaust cam cap in place, lift the cam cap off. It may be necessary to pry very lightly on the cap to lift it off its dowel pins. Do not use the cam lobes as the pry point. Be careful not to drop the dowels and also be careful to not lose the half moon shaped retainer for the bearing under the cam cap. Remove the 6 bolts that hold the intake camshaft cap and lift the cam cap off the camshaft, again, be careful to not drop the retainer or dowels. Lift the intake camshaft out of its pocket in the cylinder head casting. Remove the cam chain from the sprocket, set the stock camshaft aside. Lift the exhaust cam out of its pocket in the cylinder head casting and remove the chain from the sprocket. Do not drop the cam chain, dangle it over the side of the engine while keeping slight upward pressure on the chain to maintain its position on the drive sprocket on the crankshaft. Fit the half moon shaped retainers in the grooves of the Hot Cams camshaft bearings to ensure good fit, set retainers aside for the time. Using assembly lube, lube the shim buckets, bearing surfaces for the camshafts in the cylinder head, and pack some in the camshaft bearings. Set the exhaust cam into the cylinder head casting while at the same time fitting the cam chain over the sprocket. Make sure that you keep all the cam chain slack to the back of the engine. The cam chain pulls the camshaft sprockets in a counter clockwise direction and the slack of the chain must be kept on the cam chain tensioner side of the engine. The exhaust cam has two timing marks on it. When correctly installed one mark will be at the 9 o’clock position and the other mark will be at the 12 o’clock position. When correctly timed the mark at 9 o’clock will be aligned with the valve cover gasket surface. Repeat the above process for the intake camshaft. Again, make sure you keep the chain slack to the cam chain tensioner side of the engine. Check to be sure the crankshaft is still at TDC. The intake cam has two timing marks also. One at 12 o’clock and the other at 3 o’clock. When both cams are installed correctly, the valve cover gasket surface will form a straight line through the exhaust timing mark at 9 o’clock and the intake timing mark at 3 o’clock

Remove the plug bolt from the back of the cam chain tensioner assembly. It is under pressure from the spring. Remove the spring and pin. Remove the bolts and tensioner assembly from the cylinder. Release the lock on the tensioner assembly and push the tensioner rod into the assembly so that it is fully retracted. Remove the eight 5mm Allen headed bolts that hold the cam caps in place. Remove the cam caps; be aware of the locating dowels in the caps to keep them from falling into the engine. It may be necessary to pry very lightly on the caps to lift them off their dowel pins. Do not use the cam lobe as the pry point. Lift the intake camshaft out of its pocket in the cylinder head casting. Remove the cam chain from the sprocket, set the stock camshaft aside.

Check the location of the cam lobes. The camshafts are marked, and preset to 108-degree centers. If the lobes are not where they should be, adjust the positioning of the camshaft by rotating the sprocket one tooth on the chain. Do this until it is in the correct position as before you removed the camshafts. Check the positioning of the crankshaft for the TDC mark

Cleanliness is always a good place to start. Make sure the motorcycle is cleaned thoroughly before you start. It would be advisable to use an engine degreaser on the frame and the engine. This will ensure a clean engine during the assembly process and less of a chance of thread damage and/or dirt contamination in the engine during reassembly. And as always, replace any fiber-based gasket that was moved in any way, i.e.: cam chain tensioner. You will need basic hand tools and a torque wrench, machine towels (rags), some cleaning solvent, and a cam chain tensioner gasket. And the Hot Cams’ Degree Wheel Kit if you so desire. We will start by removing the tank and seat, top engine mount, and the cam cover. Remove the crankshaft cap and timing hole cap on the left engine case cover. Remove the spark plug. Rotate the engine in a counter clockwise (CCW) direction. Position the engine on top dead center (TDC) using the mark on the flywheel or better yet a degree wheel using a positive stop. Be sure to notice that the intake valves were the last to move, this will ensure the engine of being on “true” TDC. True top dead center occurs when both the intake and exhaust valve are closed when the piston is at TDC. This is technically the end of the compression stroke and the Page 1
beginning of the power stroke. The “artificial” TDC is during the overlap when both the intake and exhaust valves would be open. Note the positioning of the cam lobes (their included angle will be close to 170 degrees), this will help during the installation of your new Hot Cams camshafts Remove the cap bolt on the end of the cam chain tensioner block, be aware of the copper washer. Release the spring tension on the cam chain tensioner by turning the flat blade screw slot inside the adjuster block in a clockwise (CW) direction; it will lock in the retracted position. Remove the two 8mm headed bolts that hold the cam chain tensioner to the cylinder block. Remove and discard the gasket. Remove the 4 bolts that hold the exhaust cam cap in place, lift the cam cap off. It may be necessary to pry very lightly on the cap to lift it off its dowel pins. Do not use the cam lobes as the pry point. Be careful not to drop the dowels and also be careful to not lose the half moon shaped retainer for the bearing under the cam cap. Remove the 6 bolts that secure the intake cam cap and lift the cam cap off the camshaft, again, be careful to not drop the retainer or dowels. Lift the intake camshaft out of its pocket in the cylinder head casting. Remove the cam chain from the sprocket, set the stock camshaft aside. Lift the exhaust camshaft out of its pocket in the cylinder head casting and remove the chain from the sprocket. Do not drop the cam chain, dangle it over the side of the engine while keeping slight upward pressure on the chain to maintain its position on the drive sprocket on the crankshaft

1. Make sure the ignition timing is correct 2. Adjust the valves as necessary to ensure proper operation 3. Run the engine to warm it up a bit 4. Adjust the float setting. To do this, remove the carburetors (leave the throttle cables attached), remove the bowl and turn the carburetor upside down (fuel will spill). The float should look like this: Adjust as necessary by bending the float support (#37 in Figure 1). Reinstall Installation and idle adjustment 1. First you must adjust the idle. It is acceptable per the manual to adjust the idle by using the idle adjust screws (11). This usually involves screwing them then backing out 1 to 1.5 turns. Or you can adjust looking at the sliders 2. If installing the carburetors: a. Remove the cover (2) b. Reomve the slider (3) c. Place the throttle cable through the guide (18) with the spring (4) on the cable. d. Route the cable through the slide catch (6) e. Insert the slide assembly into the chamber and make sure it easily slides up and down. Direct the needle (8) into the opening of the diffuser (angled side visible). f. Screw assembly together and verify via throttle movement that slide moves freely. Attach fuel delivery lines to (12). 3. Using the idle set screw (11) raise the slider so the lower edge is 1-2 mm. 4. Assemble to engine using the proper gaskets (paper – felt – paper). 5. Using the locknut (26) adjust the free play of the throttle cable (2-3 mm) 6. Adjust the idle mixture screw – turn in completely then out 1 to 1.5 turns. * Starting using the K68′s (cold weather) 1. Verify fuel flow. Apply choke (pull 52 in Fig1). 2. Using the ticklers (13) allow fuel to enter the bowl until fuel drains from (14) 3. With the ignition off, kick 1 or 2 times 4. Turn ignition on, and as soon as engine is warmed up (maybe sooner) push choke mechanisms to open choke Idle Adjustment (engine running and warm) 1. Remove one of the spark plug caps, and with the cap shorted, adjust (11) to decrease RPM’s to a point of being minimally steady. 2. Adjust the mixture (15) out until RPM’s decrease. Turn in until RPM’s increase slightly. Then turn in screws ¼ to 1/3 revoultion. 3. Do the same for the second carburetor with the first spark plug cap shorted. 4. With both cylinders, adjust each idle (11) on each carburetor the same amount each until it’s at a steady, minimal RPM. Use small changes. (at this point you can use your airflow tool to check). 5. Sharply increase, then decrease throttle. Then engine must return to low RPMs smoothly. If the engine goes below limits, readjust (11) from step 4. Synchronization of the K68 Note: Rather than using the opposite cylinder shorted to test the pull of the live cylinder carburetor, you can use something like a Twinmax connected to the test ports (27 Fig 1). Or, if you have a model without these ports, use a Synchrometer (Appendix 2) held against the face of the carburetor. These tools merely show airflow passing through each carburetor (which is dependent on the position and wear on the slide). If using these tools, it’s not necessary to do the following steps. You wil want to use a throttle guide (Appendix 1), to show airflow at various throttle settings. Using the flow meter of your choice make sure each carburetor is the same at the various throttle settings. 1. Place the motorcycle on the center stand ensuring the rear wheel is suspended 2. Make sure you have large area to work with (safety issues here) 3. Shift into the highest gear with the engine running 4. Short one spark plug cap to the cylinder (using a nail or something in the fins) 5. Increase the speed to 40-50 km/hr 6. Fix the throttle using the throttle (maybe using a throttle stop screw under the throttle housing). 7. Reconnect other cylinder and using the opposite carburetor determine the speed which should be the same as the first. 8. Adjust the position of this slide to achieve the referenced speed using the locknut at the top of the carburetor.
