Just installed a recon cv carb on my bike , this bike has andrews cams in it can you suggest a jet set , i can start with to get it running properly ,
lots of backfiring at the moment - recon carb is a stock unit i would say.
what motor?
well sounds lean did you also use new manifold seals & new seal where carb push's in?
first check what size pilot you have now let us know & what mj. there is a few different needles too but if its stock needle that bike came with? you can put a small electric washer under the needles head to lift it up & bring the richer curve of needle in earlier. but first need to know what is in it now,
drill 46 or buy a 48 idle jet , 200 main , mixture screw 3 turns out
ive got cv with stage 1 dynojet kit with 180 jet with the clip on slot 4 but no cams so if i was you i would go the 190 160 is standerd
