hey guys i got the day off of school today and i just got to wondering about my blaster. it's going to need a new top end and maybe some work in the bottom because we found piston shrapnel down in the crank.... anyway since i've already got some engine work to do i was wondering if i should do a little something extra while she's torn down. i just would like a guide to engine mods like i've heard of big bore kits, honing, boring, porting, sleeving, and more... i'd like to know what all of these mean and how much they would cost as well as the pros and cons for each... thanks!I:I
