Bits of FJR1300 farkling
wisdom I want to keep
This page collects little bits of wisdom on FJR1300 accessories and
modifications as I come across them, things I might want to know one day but
won't be able to find later when I do.
Increasing the windshield lean angle
From jestal at fjrforum:
- Remove the windshield.
- Remove the two countersunk screws that attach the
windshield support to the tilt
- Reinstall the two countersunk screws with your selection of washers
between the windshield support and the
- Procure longer countersunk metric screws to make up the thread
engagement lost by the washers/spacers is recommended if you get too
wild with the spacers.
- Reinstall windshield onto the mount
with it's new, revised angle.
- Your results may vary. Do not try this at home. Closed course and
Warning: make sure the windshield can't engage the clutch or brake in
Windshield cutout vents
Look at the CalSci
site and copy the windshield cutout(s) you see there. Much less buffeting,
noise, and back pressure from the windshield.
Heat fixes: tank, left side, right side
Everybody swears by adding 1/8" foam adhesive heat insulation with an
aluminum barrier to the underside of the tank. My tank gets quite hot in the
summer, roasting my thighs and ... other parts of me. Insulating it keeps the
The Cromeit Fix: left side
http://www.fjrowners.ws/forum/messages/6/10176.html right side:
These fixes involve creating a barrier to close off air passages on the left
and right sides of the engine. The left is tricky, you fabricate an aluminum
bracket. On the right you stuff in some foam to block a smaller channel. Despite
the fact that it changes the engineered airflow, people swear by this. The
engine stays at two bars operating, three bars at stoplights.
At fjr1300.info there's a page about cutting holes in the nose piece but not
removing it entirely:

Folks say the altered airflow fixes some of the rider leg-heat problem without
changing overall cooling performance: still two bars while operating, three bars
Eric Villancourt says: "If you are not comfortable with the cromeit mods,
just pull the black plastic panels out of the nose and ride. Simple, cost
effective, and several people swear by it for summer riding." But this seems
like it effectively removes the radiator, because air from the front can flow
past it instead of through it. I don't know why this wouldn't cause overheating.
In the same vein, John Mortensen says, "To stop the Left side heat, seal the
space between the frame and the motor. This includes the space at the top of the
radiator around the radiator hose entry. Also seal the space between the frame
and motor under the tank on the left side. My experimentation proved that the
space between the motor and frame on the left side is where the majority of the
heat comes from. The right side does not have the same problem because of the
radiator reservoir and the cam chain. The space on the right side of the motor
is very small. If you look closely you will find a large space between the motor
and frame on the left side. This allows all the hot air to travel along the
motor and out at your ankle/calve area. I have done this fix to 5 '04 FJR's. I
used that grey dense foam that is often used to protect equipment. The motor
never gets hot enough to cause issues with the foam. Mine has been in there
working for 5 years now. If you have any other questions call me"
