I bolted a fan directly on my air-cooled AC motor, and that helped, but
in this case, it will need a directed airflow to help cool the motor.
If that doesn't help enough, insert a misting nozzle into the airflow.
However, before doing anything drastic, attach a digital thermometer to
the motor and find out exactly how hot it is getting, and then compare
that to the max value from the manual.
Cheers, Peter

A very thin coat of flat black paint might help to keep it cooler, if
it isn't already black.

at 40 mph on the flat . on my 3 kw wheel, it starts heating up to the

inch near the axle and fill the inside maybe 25% . but don't know what
kind of oil that'd not hurt wrirng etc. or would a high wattage motor
help ?
