member evil8x8 has the same machine, and i had one for a while. drain and replace the trany fluid before you run it... that kohler 17 will run great, but eats spark plugs like no 4 stroke i've ever met. if the chain tensioners are maxed out you will need to replace chain. the chains from the trany to the jackshaft are double 40, and the rest are double 50. the sprockets are pinned to the axles with roll pins. you will want to carry extras, along with a hammer and punch to drive them out and new ones in.
good luck and keep us posted
