HELP GUYS! So im leaving for a trip in two days and I'm trying to rebuild my friends banshee (my old banshee). Long story short the piston on the left side was toast and I rebuilt the top end. It was super easy to do and all I did was change the stock 347 piston to a forged wiseco 347. I didn't change anything so that way I didn't have to retune the bike. HERES THE PROBLEM: when I start the quad it fires more on the right cylinder than the left. The left barely pushes smoke at all. Also the right exhaust pipe gets hot but the left doesn't. And the best part is it back fires loud enough to hurt your ears and shoot about a 6" flame out of the exhaust. Sounds like a firecracker going off. I have a video if any body would like to see but my phone doesn't seem to let me post so let me know and I can text it to you. it has new plugs, the slides aren't in backwards, I didn't change the needle on the carbs or jetting and I'm completely lost. The only thing I can think of is somebody said there's a rubber tube that goes from one carb to the other? I see the crossover tube but it isn't rubber. Where is this located and could it cause this problem? It ran PERFECT prior to the motor losing a piston and needing the rebuild
