Steve J.: The EVO is short for the H.D. Evolution engine (from 1986 -1998/9?) It's a darned side less shaky than the Shovel, and about 200% more reliable to boot
I'm pretty sure all H.D. engines are dry sump engines, forced lubrication supplied by pump from an external tank. (There sure ain't no room in that tiny crankcase for a sump) Cheers. Peter Bancks stranged...@dodo.com.au http://www.homebuiltairplanes.com http://canardaviationforum.dmt.net
