    01 ttr 250 jets?were are they??

    ok finally got her uncorked! and road legal, went to a honda dealer for the mikuni jets, 140 main(small round) & 55 pilot. the pilot was too long so i took my dremmel and cut it to size(works perfect). put a pro circuit t-4 pipe on and opened the air box, im at sea level and it runs nice ,no flat spots or bogs,instant throttle response. WOW! what a difference!!! i havnt touched the fuel screw, i was wondering how many turns out it should be? a little loud, thinking of the 3.5" quit tip? now i need to change the gearing, what is the best setup for ridng on the road. now the front is a 13 and rear i think is 47. first 3 gears are really close,need more top end and less take off, any input would be helpful!
