1975 Suzuki T500 Running On One Cylinder?

Well, I just pulled my 1975 Suzuki T500 two-stroker out of the shed for the first time in a little over a year to get polished up and ran a little bit. I scrubbed the bike up, charged the battery, and reconnected the ignition switch, which was disconnected for whatever reason. I cleaned the plugs, put some fuel in it, and here's what happened...

The bike fired up on the 3rd kick with absolutely no assistance from WD-40 or starting fluid. It smoked quite a bit, as with any two stroke that hadn't been ran in quite a while. Until I looked, I hadn't noticed that only the left bank was smoking, so when I put my hand on the right exhaust pipe to see if it was warm - it wasn't, the cylinder was dead. I gave the bike a little bit of throttle, and the right side smoked a very little bit, so it at least tried to run. Well, I pulled the plugs out and swapped them to see if that was the problem, and it wasn't. The cylinder was just as dead as the first time. Before long a very large black spot began appearing behind the bike, so I put my hand behind the right muffler, only to get it absolutely soaked with the fuel/oil mix. :eek7: I put my other hand behind the left muffler, and nothing, it was burning everything that went in the cylinder, just like it should've been.

My question is, what could be causing the second cylinder to not run? Would it be in the ignition system, such as the points being off of adjustment? Any helps appreciated... this is really frustrating. :banghead:

I am not sure, but I think your bike had CDI electronic ignition, so there are no points. I would suggest just trial and error. Change the plug wires and boots. Check the ignition coil for power, and make sure the ground wire (kill switch) is not grounded. These bikes are really simple, and since you have isolated it to the ignition, it will not be that difficult to work out.

I would definately check your coils.
