Hey guys, any help would be appreciated. Going .040 over on the wife's wheeler. It has reeds, going to take.020 off the head, it has the FMF Fatty pipe also. My question is: To you guys that port on these things, how much have you widened the exhaust on these? I can figure the blowdown and the exhaust height, but anyone know about how much to widen them. I was going to go about 2mm on each side along with porting everything else. Thank you,Bubba
