i have a 1987 trx250x that i just had rebuilt and bored .40 over. I have put a new DG pipe on it and a uni airfilter. the problem is i cant get it to idle and at a little throttle it miss fires i geuss like its only fireing every other stroke. i tryd adjusting the idle screw and then it will ilde but if i rev it up for a sec and then let return to idle it idles very fast? havent done anything else. i think it might need to be jeted? any ideas?
