Fcr 41 Pumper On 650l

hey fellas, i just got my fcr 41 for my 650l. desmogged, stock head pipe, e2 series slip on, uni pod filter(battery now in airbox). also live at 4400 ft. i posted in the jetting thread but no help yet. it came with 170 main and 50 pilot. seems like 170 main is too rich and 50 pilot is too lean. needle is OC8(or possibly B or E)M R. should i rejet? should i s***can the battery mod and go back to using the airbox? i found out that the airbox acts as a plenum and it is necessary for intake velocity. any ideas to jet this pig so i can keep my mods in place?:applause:
