(more specifically remove the restrictive

as doing so would make the already
lean mapping way too lean, because the
tamper-proof ECM (Engine Control Mod-
ule) will not automatically (or manually)
compensate for these changes, resulting
There is no mistaking the
RMX's electric-starter motor.
The air box allows easy access
to the air filter.
The restrictive muffler muffles
