Flywheel Installation Instructions   --   #1


1.  Place bike on swing-arm stand, and remove fairings.

2.  Remove the following:
     a) counter sprocket cover
     b) clutch slave cylinder
     c) oil lines that feed into the left side of the engine
     d) trace the alternator wires and disconnect the two plugs
     e) remove the two bolts which hold the kick-stand to the engine case
     f) mark and remove the gear lever

3.  Remove the 13 cover-bolts with a 5mm Allen-wrench. Mark and remove them in order, as they are different lengths.

4.  Remove the side cover (some persuasion may be required, BE VERY CAREFUL, the cover is easy to break, and you may need a LIGHTLY rap on the edges in several spots with a plastic hammer).

5.  Catch any oil that is draining out, (this is the perfect time to change you oil).

6.  Remove the 3mm allens that hold the inductive pickups to the bracket located below the flywheel.

7.  Remove the nut and washer from the end of the crankshaft. You will need to use an impact wrench, and hold the rotor with your hand to prevent the crank from turning.

8.  Remove the rotor and the key from the key-way on the crank. Note both the orientation of the key and which side of the rotor faces the flywheel. You must replace these in the same way.

9.  Before removing the flywheel and starter-gear, please note the orientation of the crankshaft key-way and the dimple on the flywheel center piece. Remove the flywheel.

10.  Remover the starter-gear, bearing, sleeve, and shim from the back of the flywheel. The shim sometimes remains on the crankshaft.

11.  Remove the bolts from the back of the flywheel. These bolts hold the splined center piece to the steel piece, which you are replacing. They are secured with Loktite and must be removed carefully so as to not damage the heads. Use the hex-bit that is in good condition so that you do not round out the heads. Remove the dowel pin that orients the two pieces.

12.  Clean the mating face of the center piece and the threads of the bolts. Then you can install the dowel-pin into the center piece and mount the flywheel to it. Make sure to insert the dowel in the proper hole in each part and make sure the retaining clip remains secure on the dowel. If this clip comes off the dowel, the dowel may come loose from the assembly. You do not want this to happen. Secure the threads using RED Loctite #272. Torque to 70 inch pounds (8 to 10 KgM).

13.  Reinstall the starter gear, bearing, sleeve and shim into the flywheel, and mount on the crankshaft. The shim MUST NOT SLIP OFF during the re-assembly. A small dab of grease will help to hold the shim in place. Align the dimple on the splined center piece with the key-way in the crankshaft. THIS ORIENTATION IS CRITICAL. You may find it necessary to rotate the starter gear while installing the assembly onto the crankshaft.

14.  Reinstall the key, the rotor, washer, and nut. Make sure to remove all residue of old Loktite from both the nut and the crankshaft. Use RED Loctite #272 on the nut. Torque to 100-130 ft pounds.

15.  Reinstall the pickups and set the gap between them and the trigger on the flywheel at .027 (+/- .004) inches to 0.7mm, (+/- 0.1mm).

16.  Locate the two screws securing the alternator-coil in the left side engine cover. Replace these screws with the supplied button head screws. This provides additional clearance between the flywheel and the screw heads.

17.  The remainder of the re-assembly is the reverse of the above instructions. Torque the cover screws to 70 inch pounds or 0.8 to 1.0 KgM.
