DT 50 Moped Races

Hello guys, we want to take part again this year with our DT 50 in a 4h moped race. The rules say unfortunately from that we have to drive with 50 ccm. Has from you good tips like we the Zyl. best beabeiten can increase control times, channels etc. and which carburetor and exhaust combination best fits to it. We have a Gianelli and an empty org. DT50M exhaust. As a throttle we have a 19er Dellorto and a 20er Mikuni. Zyl. we have a n older and a newer Dt Zyl. It would be great of you to get some tips on the matter. I’ve already looked through a few topics in the forum but unfortunately they are partly a bit older and the links don’t work meh
