OK So my cousin just got a shee for 250 that wouldnt start and after checking it out the carbs were dirty. It has fmf gold series pipes, boisen reeds, stock air box, and I think .60 over. Good deal!!! We cleaned carbs and she started righted up but while cleaning the carbs I noticed it had stock 200 jets and the 25 pilots.... I was thinking it should be 320-330 mains and 27.5 pilots. Of course its gonna be lean w the 200 mains but what would be a good starting point? 330 then chop or higher? oh and wee in mich so 800ft alt and 70 degrees (Yeah were like 30 above normal temp here). I would rather start fatt then lean.....Thanks oh and it has yhe K n N filter not pods and no outerwear.

try 290 mains with 27.5 pilot and needle in the middle position and airscrew out 1.5 turns should be perfect :cheers:
