Jetting carb

Hi all, just aquired an old Wildstar that has straight through short shot pipes fitted and a high flow air filter. I don't think it has been jetted properly as it runs very rough above third throttle. Can any one offer some info on jet sizes and needle position please?

Buy a Barons jet kit. Example:http://www.phatperformanceparts.com/Barons_Jet_Kit_Road_Star_1600_1700_p...
The tapered needle is a major plus.
167.5 main jet, 172.5 with unbaffled pipes.
37.5 pilot jet,
Install the clip in the 4th groove on the needle with the plastic spacer and 1 silver washer below the clip.
Turn the pms screw 2.5 turns out.
Set the idle to 900-950 rpm.
If you have never been into the carb leave the float alone.
