ok i finally deciced to keep my motor its too nice to just give up. i wondered what are the best mods for my motor i just sent my head to get ported and a three angle valve job this week. it is being done by a reputable motor builder. i wondered who make the best cam for mx. i was thinking the TC stage 2 cam. i want to be untouchable! i have a friend who has a 300EX built by the same guy and it kills all the 400s it has raced so far this year but they wont tell me what they did to it. also my friend is doin the same as i am to mine he has a white bros all around cam and his motor is almost identical to mine and he wants to know what carb to run he cant afford the lectron like i have. he was thinking a LT 250R or honda 250R carb or 400Ex what is the best? and lastly will a 350X kickstarter sidecover fit on a 250X motor (my reverse is blocked off and i dont use the comp release)

thanks
