Install the Carburetors. Note: see Carburetor section for further details. Reservoir Tank Capacity: 0. The coolant is circulated by an impeller type pump mounted on the right-hand crankcase and driven by a gear. The coolant is drawn by the pump from the bottom tank of the radiator, through the pipe 1 , and discharged into the cylinder head and cylinder through the pipe 2.
The coolant passes from the cylinder head through coolant ways and after circulating around combustion chamber jacketing enters the radiator upper tank via inlet pipe 3.
The heated coolant from the engine then passes down through the finned tubes to the bottom tank of the radiator. These finned tubes present a large surface area to the air and dissipate the heat. Drain the coolant.
NOTE: Be sure to drain the coolant before disassembly of the cooling system components. Eliminate deposits from the impeller and water pump housing.
Water Pump Cover: 10 Nm 1. Water Pump Drive Gear: 12Nm 1. Disconnect e lectrical leads 2. Inspect o -ring 1 Replace if worn or damaged. Check t hermostatic valve and replace if out of specification. NOTE: Thermostat is sealed and its setting is specialized work. If its accuracy is in doubt, always replace it. A faulty unit could cause serious overheating or overcooling. NOTE: Install the thermostatic valve so that the breather hole is forward.
Install the t hermostat housing 1. Blow out obstructions with compressed air through rear of radiator. Straighten bent fins with a radiator comb. Replace if cracked or damaged. Valve Opening Pressure: kPa 0. Replace radiator cap if defective. Decrease of pressure indicates leaks in system. Locate and repair as required. Total Amount: 2. You may use boiled water or distilled water if no soft water is available. Install the r eservoir tank cap 3. NOTE: The carburetor bank can be used as a level.
Set petcock to "PRI" or use temporary fuel supply. Check that the fuel level of one carb against both left and right sides of bank is be equal. Fuel Level a : bottom of meniscus to bottom edge of the carburetor body 3. Never raise the hose while taking the measurements.
Raising the hose will make the measurement inaccurate. If the level slowly rises, the float needle valve is leaking and must be polished or replaced. NOTE: It's easy to lose track of the carb s once you flip them upside down to make that float tang adjustment. Marking the 1 carb with a piece of tape will help keep them identified.
Remove carburetor assembly. Refer to engine removal section. NOTE: The following parts can be cleaned and inspected without disassembly.
Number each carburetor before removing it from carburetor brackets. NOTE: When separating the carburetors be sure not to lose the small spring 4 that may fall out.
This spring connects the throttle levers. NOTE: Remove the needle jet toward the vacuum piston. Inspect the starter plunger 1 for damage. Replace if damaged or worn. Replace if torn or damaged. Do not use any caustic carburetor cleaning solutions. If necessary, use a single bristle from a stiff nylon brush.
NOTE: To assemble the carburetors, reverse the disassembly procedures. Pay close attention to the installation of the vacuum piston diaphragm and the location of each jet. NOTE: The float should be just resting on, but not depressing, the spring loaded inlet needle. NOTE: Float height is an approximation of fuel level. For best results, fine tune fuel level. See Fuel Level Adjustments.
A Technique for reinstalling old hardened intake boots. Note: This will probably not work on other models with long boots. This is not a Yamaha procedure. It was developed by Joe D. HAP and dv. Step 1. After soaking the rubber in a bucket of hot water, secure each air box boot to the carburetor with it's clamp.
Step 2. Slide the carbs in from the right hand side above the rubber intake manifolds on the engine and below the frame.
The free end of the boot is usually much more flexible than the end that has been attached to a hot carburetor for 20 years and will flex. Take care not to pull the boots off the carbs, especially when easing 4 around the clutch cable. This is far easier to accomplish with at least two people.
Step 3, Once the carburetors are aligned with their respective intake manifolds, ease the air box boots into their holes. There are two lips that normally sit on either side of the airbox wall. Ignore them for now.
Step 4. Pull back on the carbs enough to gain clearance between the front and the manifolds. Rotate the front of the carbs down into position. Carefully examine all around each one to ensure the rubber has not folded in front of the carb. Use a hooked too: to pull any folds out as required. Step 5, Push the carburetors forward into the manifolds.
They will snap into place as the lip engages the groove on the carburetor. Secure with clamps. Massage the airbox boots into place with a long straight screwdriver. Now is the time to ensure the sealing lips are properly positioned with one lip on either side of the airbox. Throttle Cable Free Play a : 2- 5 mm 0. Place the motorcycle on its centerstand and a garage jack under the engine.
NOTE: Do not depress the brake lever when the wheel is off the motorcycle otherwise the brake pads will be forced shut. NOTE: Lower the wheel until the discs come off the calipers.
Turn the calipers outward so they do not obstruct the wheel. Roll the axle on a flat surface 1. Replace if it is bent.
Radial 2 : 2 mm 0. Wheel is not statically balanced if it comes to rest at the same point after several light rotations. Install appropriate balance weight at lightest point on top.
NOTE: Balance wheel with brake disc installed. Failure to do so may cause an accident resulting in motorcycle damage and possible operator injury. Use soft metal drift punch and hammer. The spacer 1 "floats" between bearings.
Remove both bearings as described. Use a socket or bearing press 2 that matches outside diameter of bearing outer race to drive in bearing. Contact should be made only with the outer race. Install Front wheel. Reverse removal procedure. Use lightweight, lithium base grease.
Move the wheel towards the right side to separate it from final gear case. Measure the thickness of the b rake shoes. Use slide calipers. Inspect brake shoes. Sand glazed pads with coarse sandpaper. Inspect b rake drum inner surface. Wipe any oil off brake drum with rag soaked in lacquer thinner, brake parts cleaner or other solvent. Polish any scratches from brake drum lightly and evenly with emery cloth. Inspect c am face. Replace if worn. Grease camshaft before reassembly. Place alignment marks 1 on the cam lever and camshaft when assembly.
Axle Nut: Nm Adjust r ear brake free play. Turn adjuster 1 as needed. Use only clean brake fluid. It is not necessary to disassemble brake caliper and brake hose to replace brake pads. Remove c aliper piston assembly. Use compressed air and proceed carefully. NOTE: Be sure to reinstall the larger diameter lips of the cylinder cups first.
