[RH]
[LH]
NOTE:
To remove the exhaust manifold and heat protector on LH side, remove the cylinder head cover on LH side first. Be careful not to put any harmful materials in the cylinder head during work.
8. Remove the exhaust manifold (A).
[RH]
NOTE:
Use an universal joint wrench (B) to loosen the upper and lower nuts on the RH exhaust manifold.
[LH]
NOTE:
Use an universal joint wrench (B) to loosen the upper nuts on the LH exhaust manifold. To loosen the lower nuts on the LH exhaust manifold, use an extension bar (C) and an universal joint (D) after removing the front wheel and side cover on LH side.
