General Competition Maintenance (Off-Road Use Only)
Servicing Your Honda 41
Handgrips
Always use Honda Bond A, Pro Honda Handgrip Cement
(U.S.A. only) when replacing handgrips.
Refer to an official Honda Service Manual (page 194) for
installation instructions.
Throttle Grip/Handlebar Grip
Right throttle grip: Align the index mark on the throttle grip
with the index mark of the throttle pipe.
Left handlebar grip: Align the index mark on the left
handlebar grip with the paint mark on the handlebar.
Gaskets
Always use new gaskets when reassembling components.
Fuel Line
Refer to Fuel Line Inspection on page 61.
Check the fuel line for deterioration, damage, or leakage.
Replace the fuel line every year.
For added security, you may choose to bind the handgrips to
the handlebar and throttle pipe with safety wires to prevent the
possibility of them loosening. Position the twisted wire ends
away from your palms and be sure to bend the wire ends well
into the handgrip rubber so they will not snag your glove.
Engine Mounting Bolts and Nuts
Make sure the engine mounting bolts and nuts are tightened
to the proper torque specification.
Frame
Because your motorcycle is a high-performance machine, the frame
should not be overlooked as part of your overall off-road use
maintenance program. Periodically inspect the frame closely for
possible cracking or other damage. It makes good racing sense.
Cylinder head/Cylinder
Put a little grease on the dowel pins of the cylinder head and cylinder to
prevent corrosion from dissimilar metals. The tolerances are quite tight, so
it’s important to keep these dowels absolutely clean (pages 96, 98).
Electrical Connectors
Clean electrical connectors and wrap them with electrical
tape to reduce the possibility of unwanted disconnections,
water shorts or corrosion.
Fuse
Check the fuse before looking elsewhere for the cause of an
electrical problem.
Battery
The start button uses current from the battery.
Limited operation also allows the battery to discharge. If
you do not ride frequently, we recommend that you charge
the battery frequently (see Battery Charging on page 139).
If you do not expect to ride your motorcycle for at least 2
weeks, we recommend you remove the battery – or at least
disconnect the battery cables (negative cable first).
Fork Oil/Performance
Disassemble, clean and inspect the fork and replace the oil
regularly. Contamination due to the tiny metal particles produced
from the normal action of the fork, as well as normal oil
breakdown, will deteriorate the performance of the suspension.
Refer to an official Honda Service Manual (page 194). Use only
Pro Honda HP Fork Oil, SS-19 or an equivalent which contains
special additives to assure maximum performance of your
motorcycle's front suspension.
