Hi guys, I went thru the jetting datebase and looked at what everyone is running in the 03's. This is were my jetting is at now. main 150, pilot 52, needle stock on 5th clip down, check tps it is within the ranges. Fuel screw 3 turns out mods on bike: yosh trc comp slip on with 96db SA in it grey wire trick air box lid off and snorkel off bike, yz exhaust cam, 55 degrees out when jetting I started out with a 162 main, 50 pilot, 4th clip down on needle. oh yea AP pump is adjusted just like in the manual with no play at the lever. Bike was running way rich. dropped the main jet to 158, still rich, went down to a 150 main, plug looks a little white. still had the nasty bog:banghead: went up on the pilot 52, and dropped the needle to 5th clip. it seems better still bogs a little bit. the whole time I adjusted the fuel screw to see how it effected the bike. it seems like i need the next pilot up . in the jetting data base everyone is running a 48 or 50 pilot. any suggestions ?
