The problem with my bike was it had a slight decel pop 06 yzf 450. I'm talking very slight. So I had a quickshot cover to install and figured while I had it down I would try a 45 pilot and also had a fuel srew to put in it. So I get it back up and running with the fuel screw set on 2 1/8(this is where it was) turn out and it pops on decel real bad(very loud). So I turn the fuel screw out about to 3, same thing. I turn it back in to about 2 same thing. On 2 1/8 turn out the bike runs very good. Instant throttle response comes on strong all the way through. The popping doesn't start right away though its as I'm slowing down alot almost to a stop. I did notice that my fuel screw is very loose. It wobbles really bad side to side. I know that I have the o-ring and washer installed also I was sure to stretch the spring some. I didn't touch the main or the needle at all. I know yall have been over this alot but just trying to see what should be my starting point as this was my first time attempting something like this. If worse comes to worse I'll just put everything back stock. Thanks.
