Currently my carburator has an 118 main/pilot turned out 2.5 turns...runs perfect with FMF(also has spark arrestor in it). Would I be able to place my stock exhaust back on (since the FMF is more noise than performance) and keep the current carburator settings.IFrom what I've read the stock 114 was too lean....seems the next upgrade was a 116(maybe 118) with stock exhaust. Location is in Nevada-altitude is about 2500 feet
