I thought I recently saw a thread here about different replacement fans or fan motors for Trials bikes, I didn't pay much attention cause I didn't need one at the time. Now I can't find the thread. The fan on my Scorpa T-Ride locked up and the fan rectifier melted down in the process. I can find the Spal fan on line, but I'd be interested in a more reliable unit. I don't know why the fan needs it's own rectifier (the bike has a 12V battery) but mine is marked Leonelli 1210, I can't find any listing for that. Any suggestions?
