how do you know if you have over jetted as i have put a 98 main in the a50 and it seems to run fine however if i leave her to tick over for a minute then to wide open throttle theres a very slight yet very quick hesitation (doping) then all goes well again am i ok with this or should i size down to 96?.the only mods i have done so far is the high flow filter and the jet,no exhaust mods at all
