while my last tread sparked a interesting conv. with other members i have been on different forums and have seem posts about putting a switch on the fan relay to have the fans running all the time to keep the bike cool or reversing the fan direction. I aslo read about adding radiator shrouds to help direct air. My question is what is the best way to cool the rc down and keep it in optimal running temps. Now as far as optimal temps are consered i have heard any where from 160 to 170 is optimal.
