300 project

ok so I’m new here and by no means a atv mechanic, but I guess there is no time like the present, that being said iv worked on them before going to start with a big bore kit and possibly big red cams if I can locate some cheap, this being said I think I’m gunna go ahead and do the bottom end as well how over my head am I going to be here? Iv rebuilt Honda car motors before and tore my bayou but sold before I bought the new parts.
