I have the same set up as Matt400ex_17. I am running a 50 pilot, 195 main, the clip on the needle in the 4th slot from the top and about 2.5 turn out.

I have a 185 i tried it with like 2.5 turns out and 3 turns out then 3.5 and kept going still couldnt get it to run right with or with out my air box lid on.
I tried a 190 same thing with the turns out and with and with out my air box lid on and it still was like braking up and back fireing.
Does that mean i like need to down in my jet size or what,also i dont have to change my neddle or clip do i.My friend has a spraks pipe and has the 190 main with 2.5 turns out and it runs fine for him but it dont work out for me.
Let me know what you guys think i should do as in like goign down in the jet size or something.

Thanks.
