I have noticed that the last couple of times I rode my vtx 1300 it has cut out on me if I give it excessive throttle at low rpm's. As I was getting on the off ramp at the end of my last ride it acted like I hit the reserve on my gas tank (which i thought was weird since I only had about 60 miles on a full tank). I switched it to reserve and it was idling fine. The second I gave it throttle it started bucking really bad as if it was misfiring. I putted it home at really low rpm's...then started trying to diagnose the problem. The plugs were sooty which would indicate running rich, so I replaced all 4 plugs (the plugs on the left were kind of wet with gas, but that is the side it leans to while it is idling on the kickstand)...it still idles fine and misfires as i give it throttle. I have had my hypercharger on it for 3 years, and I re-jetted the carb with the provided main and needle jets. I checked and I am getting spark from the coils to each plug wire. I pulled the bottom bowl off of the carburetor and inspected it for varnishing...none. Aside from a very small amount of residue on the bottom of the bowl it is squeaky clean. I removed both jets and they are clean and un-obstructed. Im at a loss as to what could be wrong with it. It sounds to me like it is a dead miss, but only if i give it any throttle. Like I said it idles like it is brand new. Any suggestions?
