I'm looking to compare and/or get some tips on my jetting.i have stock porting,fatties,v-3 and k&N with flange.Modded air box lid....it's a fresh motor so i started at 48 polits,N68A needle in middle position,with 148 mains.also at sea level.I'm just starting to get color on the plug and did not do a plug chop yet.the only thing I noticed is when I come off the main and come to a stop.It pops a little bit once the rpm's come down to idle.I'm think it's rich on the main right?Any one running mods like i am to compare jetting?
All other mods are in the sig......
