rd125 lc set-up, big bore kit

[2strokecrayze...]

hi, i swapped my tzr for the lc which i was told has a 175 big bore kit and may need adjustment to the carb.
it runs fine with a few flat spots but doesnt seem as fast as the tzr and doesnt accelerate in 5th or 6th gear?
the needle is currently on 2nd down, i've tried 3rd down, it was even worse.
any idea what jet i should use? needle adjustment?
its got an allspeed exhaust.
i am happy with it , its a load of fun, just want to get that extra power out of it so i can cruise at say 75 without having to wring its neck in a lower gear?
i have browsed the site looking at carb settings etc but thought i'd post incase there are any lc people out there

cheers guys
