you are for sure more patient than i am. i would bet you won't run into problems with that screw unless you stripped the allen part or phillips(which ever it has) and you need to get it out later on for service. i have a trx 2.5 with all the cooling head bolts stripped and i cant get them out. it was done by the first owner of my truck. there is no way i can think of to get inthere with something else to get them out.
