certain conditions. Do not smoke around gasoline.
Gasoline fumes are toxic when inhaled. Perform
installation in a well ventilated area away from open
flames or sparks. Any gasoline leak or spill
constitutes a health and fire hazard.
• If motorcycle has been running, wait until engine and
exhaust have cooled to avoid getting burned during
installation.
• Electrical sparks can ignite explosive gasoline fumes.
Failure to disconnect battery while working on
motorcycle
can also result in inadvertent
engagement of starter and personal injury.
NOTE - Removing and tightening hard to reach Allen bolts like
carb-manifold mounting bolts can be greatly simplified by using

available at most automotive and tool supply houses. See Picture
