So a lot of people know now of the harbor freight 8hp 301cc engine they put out - but there isn't much info out there on them. I Now have one on my doodle/baja bug - and hopefully I can help answer some questions. It uses the same gaskets/head as the honda 270 - and pretty much everything that the 270/390 has will work with it.
My mods: adjustable 390 carb - stock one isn't adjustable
exhaust
Milled the head .052 and got the thinner head gasket
Lighter flywheel
running a 420 chain
Torque Converter
hydraulic Brake
Nitrous Kit
Put a rear tire on it tonight - damn thing is a wheelie machine!
