I just rejetted my 2005 wr450 and it wouldn't start. I ordered the kit from 6sigma on ebay. All that came with the kit was a 170 main and a 55 pilot. I was rather disappointed that the kit had no needle! Anyway, instructions said to install the jets and put the needle on 3rd clip from bottom and air fuel screw 2 turns out.
It wouldn't start until I put the stock pilot back in and 2 1/2 turns fuel screw and I had to pull the hot start in. it still runs rough and needs hot start to start cold or warm. So, since I need to use hot start to start it, would this mean that it's jetted to rich and I need to lean it out or to lean and need to richen? any help would be greatly appreciated.
My mods are: fmf slip on, gray wire cut, air box mod, ais removal.
