i have the 1410 in my crt.5 and it runs great. temps stay low, even though i am geared for about 55mph on 3s. its almost as if that motor was made for it.
They say a good mechanic only needs 2 tools - WD40 & Duct tape. If it moves, and its not supposed to, duct tape. If it doesn't move, and its supposed to, WD40.
