ENGINE REMOVAL - INSTALLATION 5 - 1
Remove the engine to frame top mounting bolts; remove the support
(figs. 4 - 5).
Remove the lower engine bolt (fig. 6).
Remove the other engine bolts.
Loosen (but don't remove) the two fork bolts, to allow easier engine
removal.
Have another technician hold the motorcycle upon engine removal; the
geometry of the frame is such that it will offset the balance (loosely
translated to "the bike will fall over when engine is removed!").
If working on cylinder head-cylinder-piston-connecting rod group, the
engine doesn't need to be removed; in such a case, the following are the
instructions:
Remove seat and tank.
Drain cooling liquid and remove the radiator clamps; it's not necessary to
remove the radiator.
Disconnect tachometer cable.
Disconnect clutch cable.
Remove the carburettor without disconnecting the throttle cable.
Disconnect the oil pressure and neutral indicator wires.
Remove ignition cover.
Disconnect starter motor wires.
Disconnect oil breather hose.
Remove rear brake fluid reservoir.
Remove brake hose to frame clamp.
Do not disconnect brake hose from reservoir.
Remove engine to frame top support.
Remove the 2 lower engine mounting bolts only.
Loosen rear damper plate to frame mounting nut / bolt (fig. 7).
Remove the bolt carefully and insert a pin in its place; this will keep the
damper in its original position and will avoid problems during installation
of the engine.
Lift the rear of the frame and with the help of another technician, separate
top frame-fork-front wheel group from engine-swing fork-rear wheel
group.
The cylinder head-cylinder-piston-connecting rod group may now be
worked on. After removing the head, the connecting rod may be checked
and replaced if necessary.
Engine installation
In either of the two cases described, assemble the components in
reverse order of disassembly.
