I would like to use 2 of these Honda clones. Duromax 440 18 HP. Modded up a bit with compression, cam, roller rockers, billit rod, etc. Looks like they should make 30 ish HP at 5000RPM.
The FWF weight might be 55# each or less. That would give a pretty good power/weight ratio.
Looking for redrives now.
