Tom Barber (aka Barbarian) and Dwayne Verhey (aka Torch) from the
FJROwners online forum figured out how to enable a North American spec'd
FJR1300 to have it's EFI's CO setting adjusted, like the European and OZ/NZ
models allow. On 03/05/03 Torch provided the following text and photos:
Note: there is a companion Web page documenting how to adjust the CO
setting.
The FJR has the capability to adjust the overall fuel injector map for each
individual cylinder right from the dashboard. The procedure is well-
documented in the European and Oceanic service manuals, and requires the
use of CO measuring instruments.
But the Yamaha decided to lock out this capability in the bikes they shipped
to North America. It was a conscious decision: they will tell a dealer how to
override the lock-out if the dealer can prove the need, but it's a big secret
from everyone else.
Not any more. This will explain how you can Europeanize (is that a word?)
your FJR so you can have it properly serviced at any shop. Or even at home if
you have the proper equipment. All you have to do is move one little wire:
the Barbarian Jumper (named after the nickname of the fellow who
discovered it.)
