I'm going through the head ache of tunning the 450r carb on my quad aswell. I thought I had it with the 50 pilot and 200 main. Then I made two laps and it started cutting out bad. I then pulles it apart to find the choke somehow got bumped and on. I am now going for a 52 pilot and I'm at a 180 main. I'm just jetting up till it stops popping on decel. As for the pilot jumps I've made I had the 50 in at 3 1/2 turns on mix to run ok. Still coughing through carb if I just bump the throttle slightly. So 52 and 2 1/2 turns is what I'm trying next. Hope this helps and your not alone brother its a headache doing this mod. But the power is sooooo worth it. This 450r carb eats!
