Hey guys put on some PC pipes and silencers. Running 280's with snorkle off and 2 1/2 turns on air screws. Runs fine through the whole power band except when i get to full throttle the left cylinder just drops. the right spark plug looks good and the left plug is just a tade darker. If any one has any ideas or suggestions that would be great!
Thanks

 

Its always the left cylinder on a banshee![img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-smile.gif[/img] My left cylinder won't run at idle when its cold. The left cylinder always blows first also.

Try two new spark plugs. Sometimes plugs can do odd things. If it isn't that, then check your float height.
