Ive only owned a banshee for about for months but it is a 96 banshee and I've added t5s, 2-1 toomey filter, vforce, coolhead, 21cc domes, +2 timing also the compression is about 125. Running a 1/3 110, 2/3 89 rec at 40:1 with 290 main and 30 pilot on the 3 clip. I got the toomeys little over a week ago and it ran like a raped ape and all of a sudden it started get a bad bog on the bottom end but it's only after about 10 min of riding, mid to wot has no issues. The first 10 minutes or so it runs amazing. I was running stock pilot, 280 main and needle on 4th clip tried switching it up and still issue. Tested stator, plug cap, wire and coil and all come back fine, on my second set of plugs, did notice some type of specs on the plugs that almost look like melted metal, I didnt notice before the toomeys. https://imgur.com/a/n6dGB7W https://imgur.com/a/5KDYZqh These pics are with 280 main, 30 pilot and the needle on the 4th. Please help, I have not been able to find anything else that i have not tried yet.
