i thought about a 416ex or possibly a 426ex bore this winter. my question is if i do this bore whould i run a stage to cam or a race cam like a tc, sparks or web race cam? im going to replace the valves. but where can i get harder rockers than stock. and how much will this cost. im thinking that in the long run it will be cheaper for me to do my yz426 hybrid than bore my motor, port and polish, new valves and rocker and a race cam. i would probably have jrspawn do the motor work.
