Hi everyone thought i would increase the power of my Scorpa SY250 2002 by fitting carbon reeds was wondering if anyone had done this improvement, built the bike back up but it wont idel and takes a few kicks to start then cuts off was wondering if you have to upgrade the pilot jets in the carb or is it a case of messing about with the air screw, was wondering if anyone knows what the set up with the carb is, i'm not that mechanically minded all help would be appreciated.
