Hi, I have a 1999 ZR700, it had a bad engine and i found a good deal on a fresh rebuilt one that i'm planning on buying to replace it, but when i put it in i'll also be putting on a new set of D&D twin pipes with trail can, gutted airbox, and boyesen power reeds. I was wondering if anyone had any suggestions as to what jetting to run for temps between 0 and 20 degrees at 0-500 sea level? also im putting on a 2000 cdi box and i was wondering if i should still change the needle clip position in the carb like i've heard about? Any input is appreciated. Thanks
